Singapore Stripe & PayPal Fee Calculator

In Singapore, Stripe assesses a standard domestic processing fee of 3.40% plus S$0.50 SGD per successful card transaction. Digital wallets such as Apple Pay, Google Pay, and Link process at the same domestic schedule with zero added gateway surcharges. In comparison, PayPal's standard commercial merchant rate in Singapore is 3.90% plus S$0.50 SGD. When accepting international cards or foreign currency settlements, both processors levy cross-border assessment fees and foreign exchange (FX) spread markups. Neither provider charges monthly account maintenance fees or setup costs for standard commercial tier accounts.

To guarantee you receive your exact net revenue target in SGD, you must calculate the gross invoice using the Mathematical Inversion Formula: Gross Amount = (Target Net Payout + Fixed Gateway Fee) / (1 - Variable Percentage Fee). For example, to receive exactly S$1,000.00 net in Singapore via Stripe (3.40% + S$0.50), the calculation is (S$1,000 + S$0.50) / (1 - 0.034) = S$1035.71 SGD. Invoicing your client for S$1035.71 ensures that after Stripe deducts S$35.71 in processing fees, exactly S$1,000.00 is settled into your account. Adding a simple 3.40% to the invoice produces a shortfall because gateway fees are deducted from the inflated gross total.

When a customer purchases using a payment method issued outside Singapore, international processing fees apply. Stripe assesses a +1.5% international card surcharge. If the transaction requires currency conversion into your payout currency (SGD), Stripe applies an additional currency conversion spread of +2.0%. Similarly, PayPal assesses a cross-border fee of +1.5% and a currency exchange spread ranging from +4.0% to +4.0% above the wholesale interbank exchange rate. For cross-border ecommerce and international freelance invoicing, these cumulative cross-border fees average between 4.4% and 7.0% per transaction.

For standard domestic transactions in Singapore, Stripe is consistently more cost-effective than PayPal. On a standard S$1,000.00 commercial charge, Stripe (3.40% + S$0.50) deducts S$34.50 SGD, whereas PayPal (3.90% + S$0.50) deducts S$39.50 SGD. Processing via Stripe saves approximately S$5.00 SGD per S$1,000 processed. While Stripe offers lower interchange rates, integrated subscription billing, and native checkout customizability, PayPal provides established consumer brand recognition and buyer checkout trust that can lift conversion rates for direct-to-consumer (D2C) retail storefronts.

The fixed per-transaction fee (S$0.50 for Stripe and S$0.50 for PayPal) heavily distorts effective fee percentages on low-value transactions. On a small S$5.00 purchase in Singapore, Stripe's total fee represents an effective deduction of 13.4%, while PayPal's deduction reaches 13.9%. Conversely, on a large S$10,000.00 B2B invoice, the fixed fee becomes negligible, and the effective fee stabilizes near the base percentage (3.40%). For microtransactions under S$10.00, merchants should explore specialized micro-payment pricing tiers, automated batch billing, or direct bank transfer rails.

Yes. In Singapore and across major global tax jurisdictions, merchant processing fees, gateway deductions, interchange surcharges, and chargeback fees are recognized as ordinary and necessary business operating expenses (Cost of Goods Sold / Financial Expenses). When filing commercial tax returns, merchants report total gross sales revenue on the top line and deduct merchant gateway fees on the expense line to calculate net taxable business income. Depending on local tax regulations, statutory Value-Added Tax (VAT) or Goods and Services Tax (GST) applied to gateway administrative fees may be eligible for input tax credits under standard reverse-charge accounting rules.

When a merchant in Singapore issues a customer refund, global card network rules (Visa, Mastercard, American Express) dictate that neither Stripe nor PayPal refund the original transaction processing fees. The customer receives 100% of their original payment, but the merchant absorbs the processing fee. If a buyer initiates a formal payment dispute or chargeback, the gateway levies a dispute fee (typically S$15.00 for Stripe and S$20.00 for PayPal). This fee is refunded only if the merchant submits valid delivery/contract documentation and the card issuer rules fully in the merchant's favor.

In Singapore, Stripe operates on an automated rolling payout schedule, depositing cleared funds into your connected local bank account within 2 to 3 business days of transaction capture. New merchant accounts undergo initial risk evaluation, during which the first payout may take up to 7 business days. PayPal deposits funds immediately into your PayPal merchant balance, with standard transfers to a linked Singapore bank account completing in 1 to 3 business days. High-risk businesses or accounts with elevated dispute ratios may be subject to rolling reserve holds (5% to 10% held for 90–180 days) to mitigate potential chargeback exposure.

Beyond standard credit and debit cards, merchants in Singapore should activate supported domestic payment methods including Domestic Singapore Cards (3.4% + 50¢), PayNow Direct (1.3% Flat). Enabling local payment rails increases checkout conversion by allowing consumers and B2B buyers to pay via their preferred national banking apps, instant bank transfers, and digital wallets. Furthermore, local payment rails frequently incur lower processing rates than international credit cards and eliminate chargeback fraud risks associated with card-not-present transactions.
