Know your true break-even before you trade again. Include fees, spreads, and coin network losses. Set smarter sell targets with clear, real numbers always.
Enter your purchase lots, then add sell-side costs. The calculator outputs a break-even sell price per coin and an optional after-tax target.
Use this sample to test the calculator quickly.
| Lot | Qty (BTC) | Buy Price (USD) | Buy Fee % | Buy Fee Fixed |
|---|---|---|---|---|
| 1 | 0.05000000 | 42000 | 0.10% | 0 |
| 2 | 0.03000000 | 46000 | 0.10% | 0 |
Try sell fee 0.10%, spread 0.20%, network fee 0.0002 BTC, and a 5% target.
1) Total invested
TotalInvested = Σ(qᵢ × pᵢ) + Σ(BuyFeesᵢ) + OtherCosts
where BuyFeesᵢ = (qᵢ × pᵢ × BuyFee%ᵢ) + BuyFeeFixedᵢ.
2) Effective sell quantity
EffectiveQty = TotalQty − CoinNetworkFee
3) Net proceeds on selling at price P
First apply spread/slippage to the price: Pnet = P × (1 − Spread)
Then apply percentage sell fees to proceeds: FeePct = (Pnet × Qty) × SellFee%
Net before tax: Net = (Pnet × Qty) − FeePct − SellFeeFixed − WithdrawalFee
4) Break-even price
Solve Net = TotalInvested for P, giving:
BreakEven = (TotalInvested + SellFeeFixed + WithdrawalFee) / ((1−Spread)×Qty×(1−SellFee%))
Break-even is the sell price where net proceeds equal total capital at risk. This calculator treats capital as purchases plus buy fees and additional costs. It also reduces sell quantity by coin-network deductions, so break-even reflects what you can actually exit in one transaction.
Dollar-cost averaging creates multiple fills with different prices and fee schedules. Maker-taker fees commonly range from 0.02% to 0.60%, and they apply every time you buy or sell. A 0.10% fee on each side is 0.20% round-trip, before any spread. Example: two lots totaling $3,400 add $3.40 in buy fees, then selling adds another $3.40 if fees match.
Quoted prices are not always executable prices. A 0.20% spread means a $50,000 quote behaves like $49,900 for your trade, and illiquid pairs can show 0.50% or more during volatility. Slippage is the extra move caused by order size and speed. The calculator models execution friction as a percentage haircut on the sell price before percentage sell fees apply.
Many exits include coin-denominated network fees and currency-denominated withdrawal fees. Losing 0.0002 BTC from a 0.0800 BTC position removes 0.25% of sellable units. Because fixed costs do not scale down, smaller positions often need a higher break-even than larger positions. If a $10 withdrawal fee hits a $500 exit, it is a 2% drag.
Break-even assumes zero taxable gain, but profit targets may trigger tax. The target mode estimates a sell price that reaches your chosen net profit after fees and taxes on gains only. If tax is 15% and you want 5% net profit, required price can rise materially. Using targets also helps align exits with planned cash needs, not just charts.
Use the net-proceeds curve to see how cash-out value changes with price. The break-even marker shows where the curve crosses your invested line, while the target marker shows your after-tax objective. The sensitivity table shifts fees and spread slightly to illustrate execution risk, helping you set conservative targets and avoid fragile plans under real market conditions.
1) Which buy price should I enter for each lot?
Use the executed fill price from your trade history. If you placed several fills close together, enter them as separate lots or use a weighted average for that period to keep the cost basis accurate.
2) How do I estimate spread or slippage?
Start with the average bid-ask spread you see during normal hours. Add extra for market orders or low-liquidity pairs. A practical range is 0.05% to 0.30% for liquid pairs, higher in fast moves.
3) When should I use the coin network fee field?
Use it when transfers reduce your coin balance, such as withdrawing to a wallet or bridging. The fee is subtracted from sellable quantity, which increases break-even for the remaining units.
4) Can it model selling in multiple transactions?
It assumes one effective exit price and one set of sell costs. For staged exits, run separate scenarios using different sell fees, spreads, and quantities, then compare the results for a blended plan.
5) Why does the target price change when I add tax?
Tax is applied only to gains above your invested amount. To reach the same net profit after tax, the gross proceeds must be higher, so the required sell price rises.
6) What are the best levers to lower break-even?
Reduce spread and fees by using limit orders, higher-liquidity venues, or fee tiers. Avoid unnecessary transfers, and watch fixed withdrawal costs. Even small savings compound across buys and the final sale.
