Membership Platform Net Income Calculator (Patreon-style)

Understanding the membership platform net income calculator — concept and principle

Creators who sell monthly memberships on platforms such as Patreon-style services receive less than the headline pledge total, because the platform takes a fee and payment processors charge for each transaction. This calculator estimates your monthly gross, the fees and the net amount you keep before taxes and your own costs. It works with any currency; the default example uses US dollars.

How it is calculated

Let M be the number of paying members, p the average pledge per month, f the platform fee in percent and q the payment processing fee in percent.

• Gross per month = M × p
• Fees = M × p × (f + q)/100
• Net per month = M × p × (1 − f/100 − q/100)

Both fees are applied as percentages of the gross. Some processors also charge a small fixed amount per payment; that is not included here, so enter a slightly higher processing percentage if your members pay small amounts.

The principle

Percentage fees scale with revenue, so the share you keep is constant no matter how many members you have: with 8% + 5% in fees you always keep 87% of gross. That makes the net easy to project: every new member at the average pledge adds p × 0.87 to your monthly net. Fixed per-payment fees behave differently: they take a larger share of small pledges, which is why low-price tiers can be less profitable than they look.

Worked example

1. Inputs: 300 members, average pledge $6 per month, platform fee 8%, processing 5%.
2. Gross = 300 × 6 = $1,800.00.
3. Fees = 1,800 × (8 + 5)/100 = 1,800 × 0.13 = $234.00.
4. Net = 1,800 − 234 = $1,566.00 per month, or 87% of gross.

How to read the result

Net per month is the amount paid out before income tax, the cost of rewards you deliver, software and your time. Multiply by 12 for a rough yearly figure, but remember that members join and leave every month, so real income moves around. To grow net income you can add members, raise the average pledge with better tiers, or reduce churn; changing platform plan only helps if the fee difference outweighs any loss of features.

Common mistakes

• Using list prices instead of the average pledge actually paid, including discounts and declined payments.
• Ignoring currency conversion fees for international members.
• Forgetting sales tax or VAT that some platforms collect on top of or inside the pledge.
• Treating net per month as profit before tax and delivery costs.

Frequently asked questions

Why is my real payout lower than the estimate?

Declined cards, refunds, fixed per-payment fees, currency conversion and payout fees all reduce the amount that reaches you.

Is it better to have more members at a low price or fewer at a high price?

With only percentage fees the share kept is the same either way; with fixed per-payment fees, higher pledges keep a larger share.

How many members do I need for a target income?

Members needed = target net ÷ (average pledge × (1 − total fee rate)). For $3,000 at $6 and 13% fees: 3,000 ÷ 5.22 ≈ 575 members.
