About CardFeeCheck
CardFeeCheck helps small business owners estimate card processing costs and compare payment options with clearer assumptions.
CardFeeCheck is an independent educational site for small business owners who want a clearer view of card processing costs. We do not process payments, sell merchant accounts, or provide custom payment quotes.
The site is built around a simple idea: business owners should be able to estimate total fees before they talk to a processor. Our calculators use public pricing inputs, stated assumptions, and business-type presets to show how percentage fees, per-transaction fees, and monthly charges can affect annual cost.
CardFeeCheck is especially focused on US small businesses comparing processors, POS systems, and fee models such as flat-rate pricing, interchange-plus pricing, and subscription pricing.
What we publish
- Free calculators for estimating card processing fees.
- Plain-English guides to payment fee models and statements.
- Provider and POS comparisons based on pricing, fit, and tradeoffs.
- Methodology notes that explain the assumptions behind estimates.
How to use the site
Start with the credit card fee calculator, compare the estimated effective rate with your statement, then read the relevant provider or POS guide before requesting quotes.
