ACH vs Card break-even calculator

Updated: January 2 (Europe/Madrid)
This ACH vs card break-even calculator tells you the invoice amount where ACH becomes cheaper than card payments. Use it to decide when to offer “Pay by ACH” (lower fees) versus “Pay by card” (faster approval), without guessing.
ACH vs card break-even calculator
Inputs
Tip: If your ACH plan has a max fee, add the cap. Break-even shifts a lot when caps apply.
Results
Use it in invoices, proposals, or your “How to pay” email.
How break-even is calculated
Fee models
Card fee = (amount × card %) + card fixed fee
ACH fee = min( (amount × ACH %) + ACH fixed fee, ACH cap ) if cap is set
Decision rule
If the invoice amount is above break-even, ACH is cheaper (lower fees). If it’s below break-even, card may be similar or cheaper depending on the fixed fee.
Official pricing references
Fees vary by provider and plan. Always confirm current rates: Stripe pricing and Square payments.
Examples (quick)
Typical freelance invoice
If your card fees are 2.9% + $0.30 and ACH is 0.8% capped at $5, ACH tends to win more as invoices grow. Use break-even to set a simple rule like “Offer ACH for invoices over $X.”
If there’s no ACH cap
Without a cap, the break-even amount may be higher (because both are mostly percentage fees). In that case, speed and customer preference may matter more than fees.
A simple policy
Put your break-even into your invoice note: “For invoices above $X, ACH is preferred to reduce fees. Card is available for convenience.”

FAQ
What is break-even for ACH vs card?
It’s the invoice amount where ACH fees and card fees are equal. Above that amount, ACH is usually cheaper (especially if ACH has a fee cap).
Why does the ACH cap matter so much?
A cap limits how high ACH fees can go as invoice size increases. When capped, ACH becomes dramatically cheaper for larger invoices.
Can I use this for any provider?
Yes. Enter your provider’s card and ACH fee terms. If your ACH plan has extra conditions (tiered pricing, additional network fees), treat this as a quick estimate.
Does ACH take longer than card?
Often yes, settlement can be slower than cards. Use break-even to decide when fee savings justify offering ACH as the preferred method.
