Calculators that use the real rules.
Every formula here is the one the Fullport engine enforces or the one a venue publishes — the rulebook with inputs. No login, nothing stored.

pump.fun bonding curve calculator
Enter how much SOL you are buying with, how much SOL the curve already holds and the SOL price. The calculator runs pump.fun's constant-product curve to give the tokens you receive, your price impact, the market cap before and after, and how far along the curve the coin is — with the 1.25% venue fee taken off the SOL first.
Prop firm challenge cost calculator
Choose an account, the list price or the public discount code, how many evaluations you are budgeting for, and your own estimate of your pass rate. The calculator returns the total fees, your chance of getting funded across those evaluations, the expected cost of one funded account and how that compares with the most one funded account can pay you.
Consistency rule calculator for prop firm evaluations
Enter your realized profit or loss for each UTC day of the evaluation. The calculator applies the 55% rule exactly as the engine does — losses included in the total, exactly 55.0% passing — and tells you whether the evaluation passes, how much more profit you need, and the range of results one more day would have to fall in to finish it.
Trailing drawdown calculator
Type the balance each UTC day closed at, and optionally the highest balance it touched during the day. The calculator ratchets the floor the way Fullport's engine does — on the close, capped at breakeven — and runs the same numbers through an intraday-trailing rule beside it, so you can see how far apart the two floors sit on the same days.
Prop firm payout and profit split calculator
Pick the account and enter the funded balance at the moment you request. The calculator finds the profit above the withdrawal buffer, applies the request cap, splits the request 80/20, and shows the balance you continue trading from — so you can time each request to get the full amount.
Crypto position size calculator for funded accounts
Enter your balance, your drawdown floor, how much of the room above the floor you will risk on one trade, where you would exit, and the liquidity of the pool. It returns the position size, how many such trades fit in your budget, and whether the order would clear a 15% price-impact cap on that pool.
