Payout Math

The general expected-value framework JJ Simon discloses in words — eval R:R, cost-to-funded, risk of ruin, and state-dependent sizing — turned into live calculators for your own numbers.

What this is, and isn't: JJ is explicit that the actual optimal stop-loss / profit-target / contract-size for every firm × plan × account size × account state is his paid product, fitted from his own backtested data — not something these videos hand over. What's below is the reusable math he describes openly (the same thing he tells his free audience to go build for themselves). Plug in your own backtested pass rates, payout rates, and account rules — not his.

01 Eval risk-to-reward

"Most likely be trading a 1.5 risk-to-reward just because a 1.5 is a $2,000 to $3,000 limit." Rule: R:R on eval should just equal the account's own profit-target ÷ max-loss ratio — nothing fancier.

ContractsStop (points)Target (points)Same $ risk/reward?

This mirrors JJ's own tiering — 25pt/38pt, 50pt/76pt, 12.5pt/19pt on his evals — where the dollar stop and target never change, only how many points and contracts deliver them, so a tighter setup can still use the same static dollar risk. Point value defaults to $20/point (NQ) since 25pt/38pt at $20 lines up almost exactly with a $500/$750 stop and target.

Symbol$/pointTo match 1 miniTo match 2 minis
NQ (E-mini Nasdaq)$201 NQ2 NQ
MNQ (Micro Nasdaq)$210 MNQ20 MNQ
ES (E-mini S&P)$501 ES2 ES
MES (Micro S&P)$510 MES20 MES
GC (Gold, 100oz)$1001 GC2 GC
MGC (Micro Gold, 10oz)$1010 MGC20 MGC

Every mini:micro pair here is a clean 10x ratio, so the same "10/20 to match" rule holds across all three: if you're sizing in MNQ, trade 10 contracts to match 1 NQ's dollar-per-point exposure, or 20 to match 2 NQ — same logic for MES vs. ES and MGC vs. GC. Swap the point-value field above to match whichever symbol you're actually trading.

02 Cost to funded & breakeven pass rate

"That means it cost you 400 bucks to get the funded account... you can just do 100 times four."

03 Funded expected value & return multiple

"Funded, you need to maximize your expected value... the probability of getting a payout multiplied by how large that payout is."

JJ's own stated target band is roughly 3–4×. Auto-fills from Section 02's cost-to-funded output until you edit it directly.

04 Full funnel — net EV across N attempts

Worked example check: 100 attempts, 30% pass, 40% payout-given-pass, $4,000 payout, $250/eval → $23,000 net. This calculator reproduces that math for your own numbers.

05 Risk of ruin

"Ideally this number is less than 0.005 — half a percent." Risk of ruin = (1 − pass rate × payout rate) ^ number of accounts your bankroll affords.

06 Value-at-risk by account state

"The same $1,000 loss reduces expected cash by different amounts... there is no universal multiplier. Rerun the numbers when the state changes." Value lost = (risk ÷ remaining drawdown room) × current account value.

State A — e.g. fresh funded

State B — e.g. $2K in profit

State A — value lost if stopped
—
State B — value lost if stopped

07 Which funded target has higher EV?

"0.33 of 2,000... 0.5 of 1,000... this trade seems more plus EV." Compare two candidate targets on a funded account by EV, not by which feels more likely to land.
