The5ers runs some of the tightest loss limits in the prop-firm industry — a 3% daily loss and 6% maximum loss on Hyper Growth — which is exactly why traders who pass tend to be the ones who size every position from the rules backwards rather than from the chart forwards. This calculator is preloaded with The5ers defaults so you can do that in one step: enter your balance, your risk per trade and your stop loss in pips, and it returns the lot size that keeps that trade inside the rules.
How this calculator is set up for The5ers
The defaults reflect a $100,000 Hyper Growth account risking 0.5% per trade with a 20-pip stop. Change any of the three inputs and the lot size updates instantly. Pip value is set to $10 per standard lot, which is correct for EUR/USD, GBP/USD and other USD-quoted majors; for gold, indices or JPY pairs, use the symbol-specific calculators linked at the bottom of this page, which carry the right pip value for each instrument.
The5ers rules that decide your lot size
Figures below are the published rules as of 2026. The5ers revises programs from time to time, so confirm on their site before you buy an account.
| Program | Profit target | Daily loss | Maximum loss | Notes |
|---|---|---|---|---|
| Hyper Growth | 10% (single phase) | 3% | 6% | Account doubles at each 10% milestone |
| High Stakes — Phase 1 | 8% | 5% | 10% | Two-phase evaluation |
| High Stakes — Phase 2 | 5% | 5% | 10% | Same loss limits as Phase 1 |
Two things stand out. First, the daily limit on Hyper Growth is 3%, not the 5% most firms use — a single trade risking 1% and two more like it ends your day. Second, the maximum loss is measured on balance, so profits you have already banked do not widen the buffer the way they do at a firm with a fixed dollar floor. Sizing has to assume the worst run of losses you can realistically hit.
The lot size formula with The5ers numbers
Lot size = (Account balance × Risk %) ÷ (Stop loss in pips × Pip value per lot)Example 1 — the default: $100,000 balance, 0.5% risk, 20-pip stop on EUR/USD.
- Risk amount: $100,000 × 0.005 = $500
- Loss per lot at 20 pips: 20 × $10 = $200
- Lot size: $500 ÷ $200 = 2.50 lots
Example 2 — wider stop, same risk: $100,000, 0.5% risk, 45-pip stop on GBP/USD.
- Risk amount: $500
- Loss per lot: 45 × $10 = $450
- Lot size: $500 ÷ $450 = 1.11 lots
Notice that the dollar risk stayed at $500 in both cases. The lot size changed because the stop changed. That is the whole point of position sizing: the stop is decided by the chart, the lot size is decided by the rules.
Sizing to the 3% daily loss limit
The question that actually matters on a The5ers account is not "how much can I risk on this trade" but "how many losing trades can I absorb today". Divide the daily limit by your per-trade risk:
| Risk per trade | Losses before a 3% daily breach | Losses before a 6% max breach |
|---|---|---|
| 1.0% | 3 | 6 |
| 0.5% | 6 | 12 |
| 0.25% | 12 | 24 |
At 1% per trade, three consecutive losers — normal variance for any strategy — end your trading day. At 0.5% you get six. Most traders who pass Hyper Growth run 0.25–0.5% for exactly this reason, and drop to the low end after two losses in a session. Remember that the daily figure includes open floating losses, so a position that is 2% underwater already counts against the day even if it later recovers.
Common sizing mistakes on The5ers accounts
- Sizing from leverage instead of risk. The5ers offers enough leverage to open positions that would breach the daily limit in a single stop-out. Leverage tells you what you can open; the formula above tells you what you should.
- Using the same lot size on every pair. Gold moves several times further in dollar terms than EUR/USD. A 2.5-lot position that risks $500 on EUR/USD can risk well over $1,000 on XAU/USD with the same pip stop.
- Ignoring spread and slippage in the stop distance. If your technical stop is 20 pips away, your real stop is closer to 22–23 pips once spread and a little slippage are included. Size on the real number.
- Adding to a loser. Averaging down doubles the position that is already going wrong. On a 3% daily limit it is the fastest route to a breach.
- Scaling up after a win streak. The maximum loss does not move up with your balance, so bigger positions after a good week put the account at more risk, not less.
Track your The5ers challenge in Fips
The calculator solves one trade. Fips's free trading journal solves the challenge. Log each trade with its risk in R, watch your running daily P&L against the 3% line, and review which setups produced the losses that ate your buffer. Connect an MT5 account and trades import automatically. The backtesting tools let you check a strategy's worst losing streak before you pay for an evaluation — if the strategy historically strings five losses together, a 1% risk model cannot survive The5ers rules and you know that before the challenge starts, not after.
Frequently asked questions
What lot size should I use on a $100K The5ers account?
It depends entirely on your stop loss. At 0.5% risk and a 20-pip stop the answer is 2.5 lots on a USD-quoted major; at a 50-pip stop it is 1 lot. There is no fixed "right" lot size — only the size that keeps one loss at or under the risk you chose.
Is 1% risk per trade too much for The5ers?
On Hyper Growth, 1% means three losses breach the 3% daily limit. That is survivable only if your strategy rarely loses three in a row, and most do. 0.5% or lower is the more common choice among traders who pass.
Does the daily loss limit include floating losses?
Yes. The5ers measures the daily limit on equity, so open positions count. Size so that even the full stop-out of every open trade stays under 3%.
Which instruments can I use with this calculator?
Any USD-quoted pair at $10 per pip per lot. For gold, oil, indices, crypto or JPY crosses use the dedicated calculators below — they carry the correct pip or point value for that instrument.
