Your school's numbers, not our claims.
Slide your student count and tuition in — see your processing savings with the no-cost surcharge option and the yield your balances could earn. Estimates in real time.
Your estimated annual impact
*Estimates for illustration only; actual results vary by card mix, state rules, and configuration. Surcharging offered where permitted by applicable law and card-network rules, with required disclosures; applies to credit cards only (never debit) and never exceeds the cost of acceptance. Yield estimates assume a variable 4.0% APY through FDIC-insured partner banks; rates change. 613OS is a financial technology company, not a bank. Not counted here: the subscriptions you stop paying for and the office hours you get back.
Two lines, both yours
The calculator counts only what we can show on a statement. It leaves out the subscriptions you stop paying for and the hours your office gets back — those are real, but they're not a line on a statement.
We specialize in lowering card rates for 501(c)(3) organizations: schools and shuls typically save 30–40% on card fees after we take over the account.
No-cost option: compliant surcharging or a pass-through line on your own tuition contract or dues statement — the institution pays nothing to accept cards, and ACH is never surcharged.
