Summary: Card processing costs for SaaS businesses, starting from a $49 average transaction and a realistic card mix. See your effective rate, not a headline rate.

Recurring revenue means the same fee is paid every month for the life of every customer, which is why a fraction of a percent matters more here than in almost any other business.

## Summary

A typical SaaS transaction is around $49. Subscriptions and invoices carry no additional Paydude percentage. At that ticket size, a 2.9% + 30¢ rate really costs 3.51%. Compare on effective rate at your own ticket size, not on headline percentages.

## What a SaaS transaction really costs

SaaS pricing tends to cluster between $19 and $99 a month, which sits in exactly the range where the fixed per-transaction fee is still a meaningful share of the charge.

**One $49 transaction, on published domestic rates**

|  | Fee | Effective rate |
| --- | --- | --- |
| Stripe 2.9% + 30¢ | $1.72 | 3.51% |
| Paydude 2.6% + 25¢ | $1.52 | 3.11% |

Those figures exclude card-mix surcharges, which the calculator above does model. Set your own volume, ticket size and card mix and the link updates, so you can share the result.

> **The fee recurs forever:** Payment fees are cost of goods sold, so they reduce gross margin and therefore lifetime value directly. On a $49 plan that is roughly 3.1% of every payment, for every month a customer stays.

## What to check on your own statement

1. **Your real average transaction.** Total volume divided by transaction count, not your list price.
2. **Your Amex and corporate card share.** Paydude surcharges these at +0.3%; most flat-rate providers fold them into a higher base rate everyone pays.
3. **Your international share.** Most providers add 1–1.5% for cards issued abroad, plus around 1% for currency conversion. Paydude does not.
4. **Monthly and gateway fees**, divided by your volume — a fixed fee only looks small at scale.

## Frequently asked questions

### What does payment processing cost for SaaS businesses?

At a typical $49 average transaction, a standard 2.9% + 30¢ rate works out at 3.51% once the fixed fee is included. Paydude publishes 2.6% + 25¢, which at the same ticket is 3.11%. Your real figure depends on card mix, which the calculator above models.

### What is the best payment processor for SaaS businesses?

For online subscription billing, any API-first processor works. Compare on effective rate at your ticket size and on whether recurring billing is priced separately — several providers charge for it as a distinct product on top of processing.

### Why is my effective rate higher than the rate I was quoted?

The fixed per-transaction fee. A quoted percentage describes only one component; the flat fee on top is a larger share of a small sale than a large one. Divide total fees by total volume on a real statement to see the true figure.

### Does card mix really change the answer?

More than the headline rate does. Amex, corporate and premium cards cost more to accept everywhere; some providers surcharge them explicitly and others fold the cost into a higher base rate. International cards add 1–1.5% at most providers. Enter your own shares above rather than accepting the defaults.
