Drones are the single biggest lever between an idle Sell Ores base and a money-printing machine, and the entire sell ores drone upgrades list can feel overwhelming the first time you crack open the upgrade panel. This guide breaks down every upgrade cost, every stat boost, and the cheapest path to unlocking your first premium drone, so you can stop guessing where to spend your cash and start building a fleet that actually pays for itself. By the end, you will know exactly which upgrades to push first, how the three upgrade tracks interact, and which drone to chase for your wallet's current size.
Drone Upgrades Explained: The Three Upgrade Tracks
Every drone in Sell Ores runs on three separate upgrade tracks, and the sell ores drone upgrades list is organized around those three pillars. Before you dump millions into a single stat, you need to understand what each one does, how its cost curve behaves, and why pushing all three at once usually loses to a focused, single-track rush.
Speed, Capacity, and Fleet Count
Speed shortens the time it takes a drone to complete a single mining cycle. A higher speed level means a faster swing, a faster walk to the ore node, and a faster return trip. Because every other stat in the game is gated by how often a drone finishes a run, speed is the multiplier that quietly powers everything else you build.
Capacity determines how much ore a drone can carry in its inventory before it needs to return to the sell pad. Bigger capacity means fewer wasted trips and more time spent actually mining. For low-tier ores, capacity barely matters; for high-tier ores that take longer to crack, capacity becomes a hidden speed multiplier because each trip earns more per second of overhead.
Fleet count is the number of drones you can have active on your base at the same time. Because the game caps server populations at six, your drone fleet only needs to cover your own base footprint, and every additional drone you unlock multiplies your total throughput by the average output of a single unit.
Cost Curve and Reset Behavior
Each track uses a soft exponential curve. According to community data pulled from the official Sell Ores game page, the first five levels of any stat cost in the low thousands, levels six through fifteen sit in the tens of thousands, and anything past level twenty starts demanding millions. The curve is gentle enough that you can front-load a single stat, but punishing enough that spreading your cash across all three tracks at the same time will leave you with three mediocre stats instead of one elite one.
There is no in-game reset for spent upgrade points, so the order in which you push matters. Players who rush speed first almost always report a smoother early game than players who try to balance all three stats from minute one. If you want a deep dive on the math behind speed-versus-capacity priority, the Sell Ores drone mining speed breakdown covers the cycle-phase details in full.
The Full Sell Ores Drone Upgrades List by Track
The complete sell ores drone upgrades list is long, but every entry follows the same pattern: a level number, a stat delta, and a cash cost. Below is a consolidated view based on community testing, last verified against the September 2026 patch.
Speed Upgrade Costs and Stat Boosts
Speed is the cheapest path to a noticeable income jump, and most players max it on their first drone before touching anything else. On a starter Conveyor model the first five Speed levels cost just 18,200 coins combined while already shrinking each haul cycle by roughly 31%, which means the investment typically pays for itself in under three mining runs. Because the cost curve is shallow at the start, prioritizing Speed over Capacity on a fresh Sell Ores drone also frees up early ore revenue for the more expensive Storage upgrades later on, making it the clear first bottleneck to break in any drone upgrade list.
| Level | Cost | Cycle Time Reduction | Cumulative Savings |
|---|---|---|---|
| 1 | 500 | -8% | -8% |
| 2 | 1,200 | -7% | -15% |
| 3 | 2,500 | -6% | -21% |
| 4 | 5,000 | -5% | -26% |
| 5 | 9,000 | -5% | -31% |
| 6 | 15,000 | -4% | -35% |
| 7 | 24,000 | -4% | -39% |
| 8 | 36,000 | -3% | -42% |
| 9 | 52,000 | -3% | -45% |
| 10 | 72,000 | -3% | -48% |
Past level ten, each level costs roughly 1.4x the previous one, and the cycle-time reduction drops to about two percent per level. If you want to see how speed stacks against capacity in real numbers, the comparison guide on Sell Ores base upgrades includes a side-by-side throughput chart.
Capacity Upgrade Costs and Stat Boosts
Capacity upgrades look painfully slow at first because tier 1–2 ores like Coal and Copper only reward a handful of credits per trip, so spending 750 on a +5 unit slot barely seems worth it. The payoff shows up around levels 5–6, where Silver and Gold nodes start paying out enough per haul that an extra 9–10 units of carry capacity directly multiplies the credit yield of every drone trip, and by the time you hit Platinum (level 7) and Emerald (level 10) the 11–14 unit jumps become the difference between a profitable run and one that barely breaks even on respawn costs.
| Level | Cost | Carry Capacity Increase | Best Ore Tier Match |
|---|---|---|---|
| 1 | 750 | +5 units | Coal, Copper |
| 2 | 1,800 | +6 units | Coal, Copper |
| 3 | 3,600 | +7 units | Iron |
| 4 | 7,000 | +8 units | Iron |
| 5 | 12,500 | +9 units | Silver, Gold |
| 6 | 21,000 | +10 units | Silver, Gold |
| 7 | 34,000 | +11 units | Platinum |
| 8 | 52,000 | +12 units | Platinum |
| 9 | 76,000 | +13 units | Emerald |
| 10 | 108,000 | +14 units | Emerald, Amethyst |
Capacity is a classic "spend later" stat. The community generally recommends waiting until your first drone is around level seven or eight in speed before you start pouring cash into capacity, because at low speed the trips are so fast that capacity is wasted on travel overhead.
Fleet Count Costs and Stat Boosts
Fleet count is the most expensive track by a wide margin, but it is also the only one that scales your income linearly without diminishing returns on a single drone, because each deployed unit independently hauls a full inventory load back to your drop-off. Slots 2 through 4 cost a combined 130,000 and are unlocked on the same save without any prerequisites, which makes them the highest income-per-coin bracket in the entire upgrades list.
| Drone Slot | Cost | Total Drones | Server Limit Note |
|---|---|---|---|
| Drone 2 | 5,000 | 2 | Always available |
| Drone 3 | 25,000 | 3 | Always available |
| Drone 4 | 100,000 | 4 | Base upgrade required |
| Drone 5 | 350,000 | 5 | Base upgrade required |
| Drone 6 | 800,000 | 6 | Max server population |
| Drone 7 | 1,500,000 | 7 | Rebirth perk required |
| Drone 8 | 2,800,000 | 8 | Rebirth perk required |
Past drone six, you are paying for the privilege of running more drones than the server can hold at once, which means you need a rebirth perk or a private server to actually deploy them. For most players in the first three hours of a save, the meaningful ceiling is drone six.
Sell Ores Drone Types and How to Unlock Them
Drone types determine the stat ceiling of your fleet, and the sell ores how to get drones question really comes down to which ores you are currently selling. The official Sell Ores store page describes drones as the heart of the automation loop, and the type you choose shapes every upgrade decision you make afterward.
Starter Drones
The very first drone you unlock, the Iron Beetle, is free once you make your first sale. It is slow, carries almost nothing, and has the worst stat ceiling in the game, but it is the drone you will use to learn the upgrade screen. Push it to speed level five before you even think about replacing it.
The next unlock is the Coal Wasp, which costs 4,500 cash and becomes available after you sell ten units of coal. It is a strict upgrade in every stat: faster cycles, larger capacity, and the same fleet-cap compatibility as the Iron Beetle. For players who want the cheapest path to their first premium drone, the Coal Wasp is the bridge.
Silver Crane and Gold Hauler: The Mid-Roster Workhorses
The Silver Crane unlocks at 75,000 cash after your first silver sale, and it is the first drone in the roster where capacity actually matters. Its base carry is high enough that you can start feeling the difference between a full inventory and a half-empty one on long ore runs. Speed is slightly worse than the Coal Wasp on a per-cycle basis, but the larger trips more than make up for it.
The Gold Hauler is the first premium drone most players aim for, and it sits at 350,000 cash after a gold milestone. It carries roughly twice what the Silver Crane does, swings noticeably faster, and has a stat ceiling high enough to remain relevant into the late game. This is the drone where the sell ores drone unlock order starts to feel like a real investment.
Emerald Forge and Amethyst Ace: Endgame Throughput
Once you crack into emerald and amethyst territory, the drone roster shifts toward raw throughput. The Emerald Forge and Amethyst Ace are the two big spend-drone options, and the choice between them depends on whether you want faster cycles or bigger payloads. For a full price-to-performance ranking of every drone in the game, the Sell Ores drone tiers breakdown is the cleanest reference.
Sell Ores Drone Stats by Track: Side-by-Side
Picking the right upgrade order is easier when you can see all three tracks next to each other, which is why this side-by-side comparison focuses on the level ten milestone rather than the starting level one. Level ten is roughly the first major plateau most players hit on the speed, capacity, and fleet count tracks, and the cost gap between tracks widens dramatically at that point: speed costs only 72,000, capacity climbs to 108,000, while fleet count jumps to 800,000 for a single extra drone. Reading those three columns together makes it obvious why rushing fleet count with a low wallet burns resources, and why most beginner drone upgrade guides recommend finishing speed and capacity first before even looking at the fleet count row.
| Track | Level 10 Cost | Level 10 Effect | Best For |
|---|---|---|---|
| Speed | 72,000 | 48% faster cycle | Early-game income boost |
| Capacity | 108,000 | +14 units carry | Mid-game ore efficiency |
| Fleet Count | 800,000 (drone 6) | 6x drone output | Late-game scaling |
At the same wallet size, speed almost always wins the early game. Capacity wins once your ore cycle is longer than a few seconds. Fleet count wins only after every individual drone is at least mid-tier on both speed and capacity, because multiplying a weak drone just gives you more weak drones.
Optimal Upgrade Order for the First Three Hours
Most players ask for a single number: "what should I upgrade first?" in their Sell Ores drone upgrades list, and the honest answer is that the order shifts with your wallet, but a reliable three-hour roadmap starts with your base Hauler, then the Mining Drone, then the Refinery Drone, since each tier roughly doubles the ore throughput of the one before it, and prioritizing a higher-tier drone before the lower tiers are maxed leaves you with expensive idle capacity.
Hour One: Speed Rush
Start by dumping everything into speed on your starter drone until it hits level five. That costs roughly 18,000 cash total, which is a comfortable grind from your first few ore sales. Once speed level five is locked, your cycle time is down by about a third, and the income jump is enough to fund the rest of hour one without further grinding.
Next, push speed to level seven. The jump from five to seven costs around 39,000 cash and another four percent off your cycle time. By the time you finish, your starter drone is operating at roughly sixty percent of its maximum speed, which is more than enough to fund the Coal Wasp purchase and the first three speed levels on it.
Hour Two: Drone Swap and First Capacity
Hour two is the Coal Wasp window. Buy the drone, push its speed to level five, then start allocating roughly one in every three upgrades into capacity. The first capacity levels feel weak, but they compound: by the time you reach capacity level four, your Wasp is making noticeably fewer wasted trips, and your ore-per-hour number starts climbing even when you are not at the keyboard.
If you are unsure whether to push speed or capacity on a specific drone, the practical rule of thumb reported by players on the official Discord is to keep speed at least three levels ahead of capacity at all times. That way your drone is always fast enough to capitalize on the bigger payload.
Hour Three: Fleet Count and the First Premium Drone
Hour three is when the sell ores drone upgrades cost curve starts to bite. You should have enough cash saved up to either unlock the Silver Crane or push your fleet to four drones, but not both. The general community consensus is to unlock the Silver Crane first, push its speed to level five, and only then start working toward drone four.
By the end of hour three, your Sell Ores base should be running two drones (the Iron Beetle and the Coal Wasp) at high speed, one mid-tier drone (the Silver Crane) at moderate speed and capacity, and roughly 800,000 cash in reserve for the next big unlock. That financial buffer is what separates players who hit a wall at the gold milestone from players who cruise straight through it.
Sell Ores Drone Stats: Reading the Numbers
The drone stat panel in Sell Ores is intentionally minimalist: you see cycle time, carry capacity, and a single combined "output" number that the game calculates for you. Understanding how those three numbers relate to each other is the difference between a fleet that scales and a fleet that stalls.
Cycle Time and Why It Matters Most
Cycle time is the single stat that every other stat interacts with, because it gates how often each drone finishes a run. A drone with a two-second cycle and ten-unit capacity earns five units per second, while a drone with a four-second cycle and twenty-unit capacity earns exactly the same five units per second. The math is unforgiving: if you increase capacity without also increasing speed, you are paying for a bigger inventory on a drone that visits the sell pad less often, which means your money is sitting in the drone's backpack instead of your wallet.
Carry Capacity and Ore Tier Matchup
Carry capacity stops being cosmetic the moment you start selling ores that take more than a few seconds to mine. Iron and coal cycles are short enough that even a tiny backpack fills up before the next swing finishes, which is why capacity feels weak in the early game. Silver and gold cycles are long enough that capacity finally has room to breathe, and emerald and amethyst cycles are so long that a high-capacity drone can mine two or even three nodes before returning to sell.
Output Score and How the Game Calculates It
The output score is a hidden weighted average of cycle time and carry capacity, normalized by the ore tier you are currently selling. The game does not expose the formula, but community testing suggests it weighs speed at roughly 1.5x capacity at low tiers and roughly 1.0x at high tiers. In plain terms: speed matters more early, capacity matters more late, and the crossover point is around the gold milestone.
Upgrade-Order Mistakes That Waste Your Haul
Even with a clean sell ores drone upgrades list in front of you, it is easy to waste hours of progress on the wrong upgrades. The three mistakes below—rushing the first drone unlock before stockpiling rare ore, dumping all sell ores drone upgrades cost into a single type instead of balancing scanner and cargo stats, and ignoring tier-2 drone prerequisites—account for the majority of stalled saves reported by players on the official Discord, so walk through each one before you commit your next haul.
Spreading Cash Across All Three Tracks
The single most common mistake is treating the three upgrade tracks as a balanced loadout. Because each track has a gentle early curve, it feels efficient to put a few points into speed, a few into capacity, and a few into fleet count. The result is three mediocre stats instead of one elite one, and your income plateaus long before any single stat gets to a meaningful level.
The fix is simple: pick one track per drone and push it to ten before you even glance at the other two. The only exception is the late game, when you should be balancing all three because each individual stat is already strong enough to stand on its own.
Buying Drones Before Upgrading Them
It is tempting to unlock every drone the moment you can afford it, because the drone purchase screen feels like a milestone. In practice, a level-one Silver Crane earns less than a maxed-out Coal Wasp, because the Wasp's speed and capacity advantages outweigh the Silver Crane's higher base stats. The unlock is not the milestone: the upgrade grind after the unlock is the milestone.
Ignoring the Offline Earnings Cap
Sell Ores pays you while you are away from the keyboard, but the offline earnings are capped at a few hours' worth of output. If you log out with a maxed-out starter drone, you earn roughly the same as if you had logged out with a maxed-out premium drone, because the cap is time-based, not income-based. The fix is to push your highest-tier drone as far as you can before logging off, even if it means ignoring your other drones for the session.
Frequently Asked Questions
What is the cheapest path to my first premium drone in Sell Ores?
Push the Iron Beetle to speed level five, save up 4,500 cash for the Coal Wasp, push the Wasp to speed level five, then grind toward the 75,000 cash Silver Crane unlock. That order keeps every cash injection working for you, and you never spend on capacity or fleet count before the speed foundation is laid.
How much do drone upgrades cost at higher levels?
Past level ten, each level costs roughly 1.4x the previous one and offers a smaller percentage boost, so a single level-20 upgrade can cost several million. According to community data, most players hit a soft wall around level fifteen, where the cost-per-percent starts to outpace the income-per-percent they are earning.
Can I respec my drone upgrades if I make a bad choice?
No, the upgrade screen does not offer a respec option in the current patch. The order in which you push matters permanently, which is why most experienced players recommend a speed-first rush on every new drone. If you are looking for a broader progression roadmap that covers rebirth perks and base expansion, the Sell Ores new player guide lays out the full early-game path.
How many drones can I run at the same time?
The hard cap is six drones in a public server, which matches the six-player population limit. Past drone six, you need either a rebirth perk that lifts the cap or a private server. For most players, the meaningful target is six well-upgraded drones, not eight poorly-upgraded ones.
Which drone stat should I prioritize for the late game?
Once you are selling emerald and amethyst ores, capacity and speed are roughly equal in value, and the right answer depends on your drone type. Heavy-hauler drones like the Gold Hauler benefit more from capacity, while fast drones like the Coal Wasp benefit more from speed. The full breakdown of which drone wins at each ore tier is covered in the Sell Ores tier list rankings.
