MyFundedFutures trailing drawdown calculator
Work out exactly where your MyFundedFutures drawdown floor sits.
Uses the official per-account-size Max Loss Limits rather than a flat percentage, applies the +$100 lock point most write-ups get wrong, and handles Rapid switching from end-of-day to intraday trailing once you are sim funded. Free, no sign-up. Rules verified 2026-07-25.

The three things people get wrong
1. The Max Loss Limit is not a flat percentage. It is published as a dollar figure per account size, and the implied percentage changes as the accounts get bigger. On Rapid, $25K and $50K carry $1,000 and $2,000 — 4% — but $100K and $150K carry $3,000 and $4,500, which is 3%. Applying 4% to a $100K account overstates your allowance by a third.
2. The floor locks $100 above your starting balance, not at it. MyFundedFutures publishes this as MLL Locks At +$100. On a $50K account the floor stops at $50,100 — so you must always keep at least $100 of profit in the account. Treating the starting balance as the resting floor tells you that you have $100 more room than you do, in the one direction that costs you the account.
3. Rapid changes basis when you get funded. During the evaluation the Rapid Max Loss Limit is measured end-of-day. Once the account is sim funded it trails your intraday equity high-water mark, so unrealized profit lifts the floor the moment it appears. The same account, the same trade, a different rule.
| Plan | Account size | Max Loss Limit | Profit target | Trails on |
|---|---|---|---|---|
| Rapid | $25,000 | $1,000 | $1,500 | End-of-day in evaluation; intraday equity once sim funded |
| $50,000 | $2,000 | $3,000 | ||
| $100,000 | $3,000 | $6,000 | ||
| $150,000 | $4,500 | $9,000 | ||
| Pro | $50,000 | $2,000 | $3,000 | End-of-day |
| $100,000 | $3,000 | $6,000 | ||
| $150,000 | $4,500 | $9,000 | ||
| Builder | $50,000 | $2,000 (or $1,500 with the reduced-MLL add-on) | $3,000 | End-of-day |
Every figure in this table comes from the plan pages listed under Sources. All of them lock at $100 above the starting balance; on Pro that lock takes effect after your first approved payout.
Worked examples
Example 1 — Rapid $50,000, still in evaluation. The Max Loss Limit is $2,000, so you open with a floor of $48,000. You finish a day at $51,200, a new end-of-day high, and the floor moves to $51,200 − $2,000 = $49,200. Give back $1,300 from there and you are out, despite being up $1,200 on the account since you started.
Example 2 — the lock point. Same account. The floor climbs until it reaches $50,100, which is your $50,000 start plus $100. That happens once your highest balance touches $52,100. From then on the floor never moves again, so everything above $52,100 is genuine cushion. Note the floor rests at $50,100 and not $50,000 — that last $100 has to stay in the account permanently.
Example 3 — Rapid $50,000, now sim funded. The basis has switched to intraday. A runner puts you at $53,000 in unrealized profit; because the peak counts immediately, the floor jumps straight to its $50,100 lock. The trade reverses and you close the day at $50,000 — below the floor. The account breaches on a day when your realized balance never moved. In the evaluation stage the same trade would have been harmless, because only the close would have counted.
See the same drawdown on a chart
A calculator tells you where the floor is right now. It cannot tell you which trades walked you toward it. If you export your futures fills, KLinePic renders them onto a candlestick chart with buy and sell markers, holding period, return, and max drawdown, so you can see whether the damage came from one oversized loser or a slow bleed of small ones. The futures trade review chart guide covers the CSV mapping, and there are per-platform walkthroughs for Tradovate and NinjaTrader exports.

FAQ
How is the MyFundedFutures trailing drawdown calculated?
Your floor is your highest balance minus the Max Loss Limit for your account size, and it only ever moves up. The Max Loss Limit is a published dollar amount per size, not a percentage.
Where does the floor stop trailing?
At $100 above your starting balance — published as MLL Locks At +$100. On a $50K account that is $50,100, reached once your highest balance hits $52,100. Assuming it rests at the starting balance overstates your cushion by $100.
Does Rapid use end-of-day or intraday trailing?
Both, at different stages: end-of-day during the evaluation, intraday equity high-water mark once sim funded. Pro trails end-of-day.
Is the Max Loss Limit a fixed percentage?
No. Rapid is $1,000 on 25K and $2,000 on 50K (4%), but $3,000 on 100K and $4,500 on 150K (3%). Use the published dollar figure for your size.
What about Flex, or a size not listed?
Pick Custom / other plan and enter the Max Loss Limit shown in your own dashboard. We would rather leave a plan out than publish a parameter we have not verified — the floor maths is identical either way.
Is this affiliated with MyFundedFutures?
No. It is an independent free calculator built by KLinePic, not affiliated with or endorsed by MyFundedFutures. Rules were verified on 2026-07-25 against the firm's public plan pages and help centre; always confirm against your own dashboard, since prop firms change parameters.
