Our crypto prop firm calculators cover the four sums every funded crypto trader ends up doing by hand: where today's loss floor sits, how big the next trade may be, whether one big day breaks a consistency cap, and how much of a profit actually reaches your wallet. Each tool loads presets from the rules the firms publish, so you type your own numbers and leave the rule values to us.
When to open each of the crypto prop firm calculators
A challenge runs into these questions in a fixed sequence. Use the tools in that sequence and you will rarely be surprised by a rule.
| Stage | Calculator | Question it answers | Main output |
|---|---|---|---|
| Before the first trade | Drawdown | How far can equity fall today and overall? | Daily floor, maximum floor, dollars of room |
| Before every entry | Position size | How large can this trade be? | Notional, units, margin, binding limit |
| After a strong day | Consistency | Is one day too large a share of the profit? | Best-day share, pass or fail, profit still needed |
| At withdrawal | Payout | What do I keep after split, fees and resets? | Amount received, net, net as % of gross |
The drawdown tool holds 68 plan presets from 27 firms and handles static, trailing, end-of-day trailing and trail-then-lock maximums. The position size tool carries per-trade caps for the handful of firms that set one, plus the BTC leverage at each firm. The consistency tool covers 29 rules at 16 firms, and the payout tool covers several dozen plans with their refund milestones and payout fees.
How the four tools fit together
The outputs feed each other. The room left under your binding floor is the "today's room" input on the position size tool. The daily results you log after each session go straight into the consistency tool. The challenge fee and any resets you paid along the way go into the payout tool, which is the only place the real cost of getting funded shows up.
A calculator does the arithmetic of a rule. Whether you pass is another matter, since that depends on how your strategy performs over the days the challenge takes.
Tools sold as "pass rate" calculators assume a fixed win rate and reward-to-risk ratio, then project them forward. Markets do not cooperate with that assumption, so we left it out and kept to the parts that are pure arithmetic.
Common mistakes the tools are built to catch
- Reading the wrong reference. Some firms take the daily limit from the start-of-day balance, others from equity at the reset. Open positions at the reset can move your floor.
- Sizing from leverage. Leverage sets margin, not risk. The stop distance and your daily room decide size.
- Ignoring the basis of a consistency cap. A cap measured against total net profit gets stricter after a losing day; one measured against the profit target does not.
- Comparing splits instead of nets. An 80% split with a refunded fee can beat a 90% split with resets and no refund.
Where the rules behind the presets live
Each preset comes from a firm's own pages, re-checked on our published methodology.

Frequently asked questions
Are the CryptoPropFirms calculators free?
Yes. All four calculators are free to use, need no account and run in your browser.
Where do the firm presets come from?
Every preset is read from the firm's own rules, FAQ or terms and re-checked on the schedule described in our methodology. If a firm changes a rule, the preset changes with it.
Can a calculator predict whether I pass a challenge?
No. Passing depends on your trading over the length of the challenge. The calculators handle the fixed arithmetic of floors, size, best-day share and payouts.
Which calculator should I use first?
Start with the drawdown calculator before your first trade, then use the room it gives you as the daily room input on the position size calculator.
