Net amount after Stripe percentage and fixed fees

Stripe's Fee Structure in Plain Terms

Stripe charges a percentage plus a fixed fee on every successful transaction. The standard rate for online card payments is 2.9% plus 0.30 per transaction in most markets. International cards, currency conversions, and premium card types add incremental fees on top. The calculator takes percentage and fixed fee as direct inputs, which means any Stripe rate structure can be modelled — standard, international, enterprise-negotiated, or specific payment method combinations. A realistic fee projection uses the actual rate from the seller's account rather than a brochure rate.

Why Small Transactions Hurt Margins

The fixed fee is the real culprit on small transactions. At 2.9% plus 0.30 a 10 transaction pays 0.59 in fees — 5.9% effective. A 100 transaction pays 3.20 — 3.2% effective. A 1,000 transaction pays 29.30 — 2.93% effective. The percentage rate converges toward the headline as transaction size grows. Businesses with average order values under 25 often see effective fee rates of 4-6% rather than the headline 2.9%. Budgeting at the headline rate underestimates actual fee drag by a meaningful amount on small-ticket businesses.

The Gross-Up Math Explained

Sellers often want to net a specific target amount after fees. Simply adding the fee to the target does not work because the percentage applies to the higher gross figure. The correct formula is (target + fixed fee) divided by (1 minus percentage as decimal). To net 100 with 2.9% and 0.30 fixed: (100 + 0.30) / 0.971 = 103.30. Charging 103.30 incurs 3.30 in fees, leaving 100 net. The calculator returns this gross-up figure automatically so sellers can price correctly.

Comparing Standard vs International Transactions

Standard domestic card: 2.9% plus 0.30. International card: 2.9% plus 1% cross-border plus 0.30. Currency conversion: additional 1% on top of the above. A 100 transaction from a domestic card nets 96.80. The same transaction from an international card nets 95.80. With currency conversion, net drops to 94.80. International customer bases pay roughly one percentage point more in fees than domestic equivalents — material across high volume.

Worked Example for a Small SaaS Business

Monthly recurring revenue 5,000 across 50 customers at 100 each. Domestic rate 2.9% plus 0.30. Per-transaction fee: 3.20. Monthly fees: 160. Annual fees: 1,920 — about 3.2% of revenue. Add 20% international customer mix paying the extra cross-border fee: annual fees rise to about 2,160. Stripe's effective rate on this business is around 3.6% of gross revenue, not 2.9% as the brochure suggests. Build pricing to cover the actual blended rate rather than the headline rate.

When Stripe Costs More Than Alternatives

For marketplaces with many small transactions, alternatives like Mollie, Adyen (at volume), or local payment rails often cost less. For subscriptions with predictable volumes, Stripe offers discounted tiers above certain monthly revenue thresholds — negotiating is possible. For businesses processing above a few hundred thousand per month, negotiating a custom rate typically saves 0.3-0.5 percentage points. Volume matters to the economics of processor selection; small businesses rarely qualify for negotiated rates and pay list price.

Fee Categories Most Sellers Miss

Dispute fee: a flat 15 per dispute on most accounts, charged regardless of outcome. Instant payout fee: 1% to transfer funds faster than the standard schedule. Currency conversion: 1% on cross-currency settlement. Tax: Stripe Tax adds a per-transaction fee on top of the base rate. Connect platform fee: the separate fee on marketplace transactions. The calculator covers the standard transaction fee; specific product fees stack on top based on the account configuration.

Practical Tips to Reduce Effective Fee Rate

Batch small transactions where possible (annual billing beats monthly for low-ticket subscriptions). Use ACH debit or bank-debit alternatives for larger recurring charges where users tolerate it (typically 0.8% plus 5 cap, much cheaper than card). Negotiate rates above 100k monthly volume. Check whether Stripe Link (saved card option) reduces card-present declines that cost failed-transaction fees. Review the monthly fees report for fees charged that were not the standard 2.9% plus 0.30 — often there are meaningful amounts in extra categories.

What the Calculator Does Not Include

Dispute fees, currency conversion fees, instant payout fees, Stripe Tax fees, Connect platform fees. These stack on top of the base transaction fee. Monthly base fees for premium accounts. Minimum monthly fees for small accounts. Chargeback-related adjustments that sometimes claw back the fixed fee on refunds. The calculator focuses on the standard transaction fee structure; complete fee projections require adding any of the above that apply to the specific account setup.
