Your break-even price is always higher than your buy price due to trading fees.
What this calculator does
On a 0.5% fee exchange, buying
0K of BTC requires a 1% gain just to break even.
When to use this calculator
Use this calculator before executing any trade — not just after. Knowing the exact net proceeds after fees and estimated taxes gives you the true profit figure, not the gross amount that the exchange displays.
Common mistakes
A common mistake is confusing gross return with annualised return. A 60% gain sounds impressive until you factor in it took 4 years — which is an annualised CAGR of about 12.9%, useful context for comparing against other investments.
Real-world scenarios
An investor compares a 6-month crypto return of 45% against the annual return on a stock portfolio of 22%. Using the annualised CAGR mode reveals the crypto position generated approximately 105% annualised — context that makes the comparison meaningful.
