CSV upload, not OAuth<br>Many fee tools ask for permanent read access to your Stripe account — transactions, customers, payouts. We never connect to Stripe: you export a Balance CSV, upload it, get the report. Raw CSV is processed in memory and not stored as a file.

The report turns a raw Balance CSV into a plain-English answer to: is this rate normal, what is driving it up, and what should I look at first?

Calculator vs reality<br>Fee calculators estimate. Your Stripe CSV tells the truth.<br>A calculator is useful before you sell. Once payments are live, your Balance export shows the real mix: international cards, refunds, small charges, payout fees, and monthly drift.

2.9% + $0.30<br>✓Uses product price and rough assumptions<br>✓Good before you launch or change pricing<br>✓Misses refunds, card mix, add-ons, and real monthly drift

What the report tells you<br>Not just a number — a full breakdown<br>RATEProcessing rate vs all-in cost<br>Separate the card/charge processing rate from the all-in Stripe cost rate across refunds, payouts, disputes, and other fee lines.

BENCHIs your rate normal?<br>A rough benchmark range for your transaction mix, so you can see whether your rate is expected or unusually high.

WHYWhy your rate is higher<br>International cards, small transactions, Amex, currency conversion — pinpointed by transaction.

REFUNDRefund fee leakage<br>Estimate how much retained processing fees on refunds are quietly eating into margin.

SAVESavings opportunities<br>Directional annual estimates for ACH, local payments, or bundling — prioritization, not guaranteed savings.

In real Stripe exports<br>What we often find<br>Not always a problem — often mix, refunds, or small-ticket math worth a second look.<br>International cards quietly adding cross-border fees

Small $5-$20 charges where the fixed $0.30 fee dominates

Months where your fee rate jumped without an obvious reason

Large B2B invoices that could be cheaper via ACH

A 4.5% blended rate that may be normal — or a sign something is leaking margin

Is it worth it?<br>When a fee audit is useful — and when to skip it<br>Start with a free preview — headline rate, top drivers, and a teaser. The $12 unlock is for founders who want line-level drivers, refund leakage, monthly detail, exports, and specific savings ideas.<br>Worth checking<br>✓You process more than a few thousand dollars per month<br>✓Your customers are international or pay in multiple currencies<br>✓You have many $5-$20 monthly charges<br>✓You refund customers often and want to see retained fee impact

Probably okay to skip<br>•You only have a handful of Stripe transactions<br>•All customers are domestic and high-ticket<br>•You only need a rough blended rate you can calculate in Excel<br>•You need accounting or tax advice instead of a fee audit
