Three choices. Same holding.
Each choice starts from your full holding. These are alternatives, not consecutive sales.
What if Bitcoin moves afterwards?
Cash from the sale + the later value of remaining BTC. Compared with keeping everything. Cash is assumed unchanged, with no interest or reinvestment.
Combined cash and BTC value, before tax and future selling costs
Recovering your original cash does not make the rest risk-free. Remaining Bitcoin can still lose value. A cash withdrawal is not the same thing as profit, and neither is an estimate of your tax bill.

The maths, without the guesswork.
How much BTC must I sell?
For a cash target T, sale price P, percentage fee f as a decimal, and fixed charge F:
BTC to sell = (T + F) ÷ [P × (1 − f)]
The calculator rounds the sale up to the next whole satoshi to reach the target. It rejects a plan that would leave less than your minimum BTC. A percentage sale rounds down to a whole satoshi. No sale means no sale fee.
There is no universally optimal amount to sell. This tool makes the trade-offs visible; it does not choose a strategy, predict a peak, or place orders.
A worked cash-out example
Suppose you hold 0.1 BTC, paid $5,000 in total, and assume a sale price of $100,000/BTC. With a 0.5% sale fee and $20 fixed charge, withdrawing $2,000 requires selling approximately 0.02030151 BTC.
You keep 0.07969849 BTC. The sale costs approximately $30.15 in fees. About $1,015.08 of the original purchase cost is allocated to the sold BTC, leaving approximately $984.92 illustrative profit on that portion, before tax.
Recovering the whole $5,000 instead requires a larger sale. Compare both choices above without confusing cash received with profit earned.
Does this calculate tax or money arriving in my bank?
No. It calculates proceeds after only the costs you enter. Tax, exchange limits, settlement, banking charges you omit, slippage and execution differences can change the actual amount available. The pro-rata allocation of purchase cost illustrates the arithmetic; it does not implement any country's tax-lot rules.
Can I use pounds or euros?
Yes, by entering every money amount in the same selected currency. Switching the label does not convert existing numbers. The optional market snapshot is USD-only. The default numbers are hypothetical.
Why does selling help in one scenario and hurt in another?
Selling reduces exposure to future price changes and incurs fees. After a fall, the cash you kept may make the combined value higher than holding everything. After a rise, the Bitcoin sold no longer participates in that gain. The comparison assumes one sale at the entered price followed by the later scenario price.
What if my cash target is impossible?
The plan is marked unavailable. Where possible, it shows the minimum sale price needed while keeping your chosen BTC floor. That is an arithmetic threshold, not a price target or an assurance the market will reach it.
