Payout Optimisation
Maximise what you actually take home — splits, tax, frequency, and the buffer rule.
00 — Why This Matters
The Money You Earn Is Not the Money You Keep
Two traders earn the same 3% monthly return on the same £100K funded account. Same strategy. Same edge. Trader A: 90/10 split, monthly payouts, does not track expenses, pays tax on gross. Takes home £1,890/month. Trader B: 80/20 split, bi-weekly payouts, deducts £300/month in challenge fees and expenses, sets aside 30% for tax. Takes home £1,820/month — but survives 3× longer because the wider DD rules at the 80/20 firm protect the account. After 12 months: Trader A earned £9,450 (terminated Month 5). Trader B earned £21,840. Same skill. Different payout strategy.
⚡ REAL SCENARIO
The difference between £9,450 and £21,840 is not trading skill. It is payout optimisation: understanding splits, timing withdrawals, tracking expenses, and choosing firms where you survive long enough to collect.

The Buffer Rule & When to Compound
Always leave at least 2% of your starting balance as a buffer in the funded account before withdrawing. If your starting balance is £100K, keep £2,000 minimum. This protects against a bad start to the next payout cycle.
If you are building toward a larger account (or the firm offers scaling based on total profit), compound for 2–3 months to hit the next tier. The increased balance generates more income than the payouts you delayed.
Once you have 3+ funded accounts and consistent monthly income, withdraw regularly. The income is the point. Hoarding profit in funded accounts does not earn interest and adds drawdown risk if the account is lost.
Leaving money in a funded account does not change your tax liability. HMRC (UK) taxes you on realised profits regardless of whether you withdraw. Compounding to "avoid tax" is a myth that leads to poor financial planning.

07 — The 30% Rule
Set Aside Tax Before You Spend
THE RULE = After every payout, immediately transfer 30% to a separate savings account labelled “Tax Reserve.” Do not touch this money until Self Assessment is due.
WHY 30% = Basic rate Income Tax (20%) + Class 4 NI (~6%) + Class 2 NI (~£3.45/week) ≈ 27%. The extra 3% provides a buffer for underpayment estimates, late payment interest, and the peace of mind of knowing tax is covered.
SEPARATE ACCOUNT = If tax money sits in your current account, you will spend it. A separate savings account with no debit card creates a psychological and practical barrier. When HMRC asks for payment, the money is already waiting.
THE FORMULA = Payout → 30% to Tax Reserve → 2% stays as account buffer → remainder = your actual take-home. Plan your lifestyle around this number, not the gross payout.

Payout Quick Reference
LONGEVITY BEATS SPLIT = 12 months at 80/20 beats 5 months at 90/10. Total income = months survived × monthly payout.
2% BUFFER = Always leave 2% of starting balance in the account after withdrawal. Never strip it bare.
30% TAX RESERVE = Immediately after every payout, 30% goes to a separate tax savings account. No exceptions.
TRACK EVERYTHING = Every payout, every challenge fee (including failures), every expense. Failed fees are deductible. Missing them costs you real tax money.
THE RULE = Your actual income = payout − firm split − tax − expenses. Optimise the whole equation, not just the split percentage.
