Free crypto calculators
Nine of them. The arithmetic you end up doing in a notes app at two in the morning. No account, no sign-up, nothing sent to a server — every one of these runs entirely in your browser.
Cost basis and profit
What a position cost, what it is worth, and what gets you back to level.
Crypto profit calculator
Profit, loss and ROI on a closed trade, with the fee counted on both sides the way your exchange bills it.
Entry, exit, quantity, fee
Average down calculator
Your blended entry after buying more on the way down — weighted by size, which is the part people get wrong in their head.
Up to five buys
DCA calculator
What buying on a schedule actually averaged — and why that lands below the average price rather than on it.
Amount, frequency, price range
Break-even calculator
The exit that gets you level after fees, plus the gain a position needs to climb back from where it is.
Entry, fee, drawdown
Position and risk
Size, stop, ratio and the price at which a leveraged position stops being yours.
Position size calculator
How much to buy so a stop-out costs a fixed percentage of the account, and nothing more.
Balance, risk %, entry, stop
Stop loss calculator
Where the stop sits for a distance you choose, what it costs, and whether the target justifies it.
Long and short
Risk/reward calculator
The ratio — and the win rate that ratio needs before the setup makes any money.
Entry, stop, target
Leverage calculator
Effective leverage from margin and position value, plus what a single percent against you costs.
Margin, exposure, liquidation gap
Liquidation price calculator
Where the exchange closes a leveraged position and keeps the margin. Long or short.
