Square vs Stripe Fee Comparison

How to Use the Square vs Stripe Calculator

The Square vs Stripe calculator compares monthly transaction fee costs. Just enter two numbers: the average transaction amount and the number of transactions per month. The tool immediately shows how much you would pay with Square per month, how much with Stripe, and which platform is cheaper.

The default rates are estimates: Square 2.6% + $0.10, Stripe 2.9% + $0.30. You can replace them with your own rates — for example, the ones from current pricing or the terms on your account.

1. Enter the average transaction amount.
2. Enter how many transactions you process in a month.
3. Check or change the percentage rates and fixed fees.
4. Read the results: the Square cost, the Stripe cost, and how much less one platform costs per month.

The calculator shows amounts in US dollars because the default rates are quoted in that currency. If you enter your own rates, you can calculate in any currency — just make sure the transaction amount and fees are in the same currency.

How Monthly Transaction Fees Are Calculated

The calculator figures monthly transaction fees in a simple way. First it checks how much commission one transaction uses, then it multiplies that cost by the number of transactions per month.

Fee per transaction = transaction amount × percentage rate + fixed fee. Monthly fee = fee per transaction × number of transactions per month.

Example: average transaction amount $100, 200 transactions per month, and the rates shown in the calculator.

Result: Square is cheaper — by $100.00 per month. The difference comes from two parts: Stripe's higher percentage (0.3 percentage points, or $0.30 per transaction) and its higher fixed fee ($0.20 per transaction). With 200 transactions, that adds up to $100.00.

Differences Between Square and Stripe Rates

In the calculator, Square has both rates lower: a lower percentage (2.6% vs. 2.9%) and a lower fixed fee ($0.10 vs. $0.30). These are estimates — before deciding, check the current pricing for both platforms, because rates depend on factors such as country, payment type, and the terms on your account.

Here is what that means for your costs:

• Percentage rate grows with the order value. The higher the average transaction amount, the bigger the difference on each individual transaction.
• Fixed fee works the other way — it weighs more heavily on your total when you have more transactions, especially when individual orders are low.
• Business scale amplifies both effects, because the monthly cost is the sum of fees from hundreds of individual transactions.

That is why you should compare platforms using your own numbers, not a general impression. A seller with many low-value orders will feel the fixed fee much more than someone processing a few dozen higher-value transactions.

When Square Is Cheaper and When Stripe Is Cheaper

With the rates entered in the calculator — Square 2.6% + $0.10 and Stripe 2.9% + $0.30 — Square is cheaper. In this setup, it has both a lower percentage and a lower fixed fee, so it wins at every transaction count and every average transaction amount.

In the example above, the difference is $100.00 per month. The situation changes when you enter your own rates — then the fee structure decides the result, not the platform name.

• Many low-value transactions — the fixed fee matters more, so the platform with the lower per-transaction charge wins.
• Fewer, higher-value transactions — the percentage matters more, so the platform with the lower commission wins.
• Balanced sales profile — check both fields at once, because the difference can be small and changes with order volume.

Do not assume one platform is always cheaper. Check current pricing and enter the rates that actually apply to you.

Limitations and What the Calculator Does Not Include

The calculator compares only monthly transaction fee costs. That is a narrow slice of the full bill, so treat the result as an estimate.

• It does not include other platform fees, such as refunds, chargebacks, payouts, currency conversion, subscriptions, or additional services.
• It does not calculate taxes or accounting and legal costs.
• It does not convert currencies — amounts are in the platform currency ($), and exchange rates change daily.
• It does not know your individual terms: negotiated rates, discounts, pricing plans, or rates that depend on payment type.
• It does not check whether the rates entered in the fields match current pricing — that is up to you.

The result is a good starting point for a conversation about costs, but it does not replace pricing. Before deciding, check the current rates for both platforms and compare them with the full list of fees that apply to your business. Also remember that when you enter your own rates, you can calculate in any currency.
