A $100K account with 8% monthly return - how much do you actually earn after the prop firm split and success fee? Concrete calculations for different scenarios and account sizes.

A prop firm boasts "80% profit split." Sounds great. But between the catchy slogan and an actual transfer to the trader's account, there are several steps worth understanding before buying a challenge.
Let's take a concrete example:
Calculations:
For every $8,000 gross profit, the trader receives $4,480 - which is 56% of the result.
Is that a lot? Let's compare with the alternative - own capital trading:
Own capital $10,000:
$100,000 prop account with management:
A managed prop account delivers 6.4x higher monthly income with own capital exposure limited to a one-time challenge fee.
Assuming 8% monthly return, 80/20 profit split, and 30% success fee:
| Account Size | Gross Profit | After Prop Split | After Success Fee | To Trader |
|---|---|---|---|---|
| $50,000 | $4,000 | $3,200 | $2,240 | $2,240 |
| $100,000 | $8,000 | $6,400 | $4,480 | $4,480 |
| $200,000 | $16,000 | $12,800 | $8,960 | $8,960 |
| $300,000 | $24,000 | $19,200 | $13,440 | $13,440 |
These are numbers at a constant 8%/month rate. In practice, results fluctuate - good months compensate for weaker ones. But the scaling effect is clear: a $300K account generates 6x more for the trader than a $50K account.
Someone might ask: if I have to give 30% to the manager, why bother?
The answer lies in risk distribution:
Without management: Trader passes the challenge themselves (cost + time + failure risk), manages the funded account themselves (full psychological responsibility), bears consequences of mistakes themselves (account loss).
With management: Trader pays the one-time challenge fee, manager takes responsibility for results and rule compliance, trader keeps 70% of their profit share without active involvement.
If the alternative is "I earn 100% from weaker self-managed results or nothing (after losing the account)" vs. with management "I earn 70% from professionally managed results" - the math often favors managed accounts.
PropGate charges a success fee only on realized profits. If a given month is a loss or break-even - we don't charge a fee. Traders don't pay for underperformance.
This is a structural guarantee of aligned interests: we only earn when you earn.
Before choosing any account manager, make sure:
Fee transparency is the minimum you should demand from a partner managing your capital.
