To receive your exact contract amount after Stripe or PayPal fees, use the reverse gross-up formula: Invoice = (Net Desired + Fixed Fee) / (1 - Rate). Standard addition leaves you short because transaction fees apply to the new higher invoice total.

1. Can You Pass Stripe and PayPal Fees to Clients?
Yes, you can legally pass processing fees to clients either by itemizing a credit card convenience surcharge (where permitted by state and national laws) or by grossing up your base service fee. Because direct payment surcharging is heavily regulated or capped in certain jurisdictions, the safest industry standard is including merchant costs within your gross quote or offering an early-settlement discount for ACH and bank wire transfers.
2. The Common “Simple Addition” Math Trap
Most business owners make a critical mathematical error when trying to offset transaction costs:
A contractor wants $1,000 net. Stripe charges 2.9% + $0.30.
The contractor calculates 2.9% of $1,000 = $29.00 + $0.30 = $29.30.
They invoice for $1,029.30.
Why This Fails:
When the client pays $1,029.30, Stripe calculates its 2.9% fee on the new, higher gross total:
- $1,029.30 × 0.029 = $29.85
- Plus fixed fee: $0.30
- Total processor deduction: $30.15
- Actual Net Payout Received: $1,029.30 – $30.15 = $999.15 (You are short $0.85).
3. The Reverse “Gross-Up” Formula That Solves It
To receive your exact target payout, use the correct algebraic reverse gross-up equation:
Invoice Amount = (Desired Net + Fixed Fee) / (1 - Percentage Fee)
Practical Solved Example ($1,000 Target Net):
- Desired Net = $1,000.00 | Fixed Fee = $0.30 | Percentage Fee = 0.029 (2.9%)
- Calculation: (1,000 + 0.30) ÷ (1 – 0.029) = 1,000.30 ÷ 0.971 = $1,030.18
- Fee Deducted: (2.9% × $1,030.18) + $0.30 = $29.88 + $0.30 = $30.18
- Final Net Deposited in Your Bank: Exactly $1,000.00.
4. Legal & Compliance Framework: Know Your Local Surcharging Laws
Before adding a line item titled “Payment Processing Fee” to an invoice, verify the legal statutes governing your client’s billing jurisdiction:
| Region / Jurisdiction | Surcharge Legality | Key Compliance Requirement |
|---|---|---|
| United States | Legal in most states | Capped at actual processing cost (max 3% or 4%). Restricted in CT, MA, and PR. Debit card surcharges are federally prohibited. |
| United Kingdom & EU | Prohibited on B2C Cards | Under PSD2, surcharging consumer cards is illegal. Commercial B2B corporate cards can be surcharged up to direct processing costs. |
| Canada | Permitted (2.4% Cap) | Merchants can surcharge credit cards up to a 2.4% cap with advance notice. Quebec consumer protection laws restrict B2C surcharging. |
| Australia | Cost-Reflective Only | RBA regulations require that surcharges do not exceed the actual cost of acceptance. Excessive surcharges trigger ACCC penalties. |
5. The 3 Best Strategic Ways to Pass Fees to Clients
Build the 3% processing buffer into your standard service rate, and offer a discount for low-cost rails: e.g., “Standard project fee is $5,150. Settle via ACH, EFT, or Direct Bank Wire and receive an instant 3% early-settlement discount ($5,000 net).”
In jurisdictions where B2B fee recovery is standard, state: “Invoices settled via credit card or digital wallet (PayPal/Stripe) are subject to a merchant processing fee of 2.9% + $0.30 per transaction.”
Top creative and engineering agencies simply round their billable quotes to accommodate typical overhead costs (merchant fees, software licenses), keeping client goodwill intact.
6. Frequently Asked Questions
Can I charge clients for PayPal Goods & Services fees?
PayPal’s User Agreement discourages charging a direct fee explicitly labeled as a “PayPal surcharge”. However, you are fully entitled to set your gross invoice price at a level that accounts for business overhead and transaction costs using the gross-up formula.
What is the fee difference between ACH transfers and credit cards on Stripe?
Stripe charges a low fee for standard ACH direct debit payments: typically 0.8% capped at $5.00. For a $10,000 invoice, credit card processing fees total roughly $290.30, while an ACH transfer costs a maximum of just $5.00.
Does a gross-up increase my taxable gross revenue?
Yes. When you gross up an invoice from $1,000 to $1,030.18, your gross taxable income is $1,030.18. However, the $30.18 deducted by Stripe or PayPal is categorized as a deductible business expense (Merchant Processing Fees), resulting in the same net taxable income.
Is credit card surcharging legal in the UK and EU?
Under EU PSD2 rules, surcharging B2C consumer credit and debit cards is prohibited. However, commercial B2B corporate cards can be surcharged up to direct processing costs.
