Cash Discount Program Calculator: How to Run the Numbers Yourself
To calculate a cash discount program, raise your posted card price using this formula: (base price + per-transaction fee) ÷ (1 − your percentage rate), then give cash payers a discount back to the base price. For example, with a 3% effective rate and no per-item fee, a $100 item becomes $103.09, you keep $100 after fees on card sales, and the cash discount works out to 3% off the posted price.
Key takeaways
- Gross up, don't just add your rate. A 3% processing cost needs a 3.09% price increase, because the processor's fee also applies to the amount you added.
- The markup percentage and the cash discount percentage are not the same number. Raise prices 4% and then take 4% off, and a $100 item ends at $99.84, below your old price.
- On small tickets, include the per-transaction fee in the formula. A flat percentage markup leaves money on the table on every small sale.
- Card brand rules generally keep surcharges off debit and prepaid cards and cap them. Cash discount programs are structured differently. Rules vary by state, so confirm with the card brands and your state before changing prices.
- Calculator savings assume you keep every customer and your card mix stays the same. Tips, refunds, chargeback fees, and program or equipment fees still cost money.
How a cash discount program works
In a cash discount program, the price on your shelf, menu, or invoice is the card price. Customers who pay cash get a discount at the register. Your processing fees don't disappear. Card-paying customers cover them through the higher posted price, and cash customers get that amount back.
A surcharge flips how the price is presented. The posted price is the cash price, and a fee is added at checkout when the customer pays by credit card. Card brands treat a surcharge as a fee for accepting cards. That means caps, disclosure requirements, and generally no surcharging on debit or prepaid cards.
A cash discount is framed as a discount for paying cash, which is why it can typically apply across all card types. The discount still has to be real and clearly disclosed. Rules vary by state, so confirm with the card brands and your state before you change your pricing.
Either way, you are solving for the same number. How much do you raise the card price so that, after the processor takes its cut, you keep what you would have kept on a cash sale?
The formula, and the mistake most articles make
Your processor charges its fee on the full card ticket, including the amount you added to cover that fee. So a 3% increase does not fully cover a 3% cost. You have to gross it up: card price = (base price + per-transaction fee) ÷ (1 − percentage rate). Example: a $100 base price at an assumed 3% effective rate becomes $100 ÷ 0.97 = $103.09. The processor takes $3.09 and you keep $100.00. A plain 3% increase would leave you $99.91. That's small on one sale, but it repeats on every card transaction.
Here is what most articles get wrong: they treat the markup and the cash discount as the same percentage. They aren't, because each is calculated on a different base. Raise a $100 item 4% to $104, then give cash customers '4% off,' and they pay $99.84. That is less than your old price. The discount that brings cash customers back to exactly $100 is 3.85% off the posted price ($4 ÷ $104). In the grossed-up example above, the cash discount equals your effective rate: $3.09 off $103.09 is 3.0%. Set the markup and the discount separately, both anchored to the same base price.
Per-item fees matter on small tickets. Example: an $8.00 coffee at an assumed 2.7% + $0.10. The math is ($8.00 + $0.10) ÷ 0.973 = $8.32, which is a 4.06% increase. A flat 2.7% markup would price it at $8.22 and leave you about 10 cents short on every sale. The smaller your average ticket, the more a flat percentage under-recovers.

A worked monthly example
Example restaurant: $60,000 a month in sales at base prices, with 85% paid by card ($51,000) and 15% in cash ($9,000). We'll assume a 2.75% effective rate, the restaurant industry estimate our tools use, not a quote. Today that restaurant pays about $1,402.50 a month in processing and nets $58,597.50.
With an exact-recovery cash discount, card prices rise 2.83% (0.0275 ÷ 0.9725). Card customers pay about $52,442, fees come to about $1,442, and the restaurant keeps $51,000. Cash customers get the discount and pay $9,000. Net revenue is $60,000, about $1,402.50 a month better than today, assuming the same transaction count and card mix.
With a rounded 4% program, posted prices rise 4%. Card customers pay $53,040, fees are $1,458.60, and the restaurant keeps $51,581.40. If cash customers get '4% off posted,' they pay $8,985.60. Net revenue is $60,567, about $1,969.50 better than today. The extra comes from card customers paying more than the actual processing cost. That affects how customers perceive your prices, and it may affect how your program has to be structured and disclosed. Confirm that with the card brands and your state.

Open the free Cash Discount vs Surcharge ComparisonCash discount vs surcharge: where the numbers split
Under a surcharge, debit is generally excluded by card brand rules, so you keep paying fees on that volume. Take the same example restaurant and assume 60% of card volume is credit ($30,600) and 40% is debit ($20,400). If debit costs an assumed 1.75%, the restaurant still absorbs about $357 a month after surcharging credit. Brand caps can also sit below your actual cost of acceptance. If that happens, the surcharge won't cover all of your credit fees either.
The customer experience differs too. A cash discount means every customer sees higher prices on the menu at first glance. A surcharge keeps your posted prices lower but adds a line at checkout that some customers notice and dislike. Which one costs you more goodwill depends on your customers and on how price-sensitive your category is.

Costs a calculator won't show you
Tips and refunds: if customers tip on top of the card price, you pay the percentage fee on the tip as well, and the markup doesn't cover it. Refunds go back at the price the customer paid, and your processor may not return its original fee. Chargeback fees are flat per dispute, so no price increase offsets them.
Lost customers: every savings estimate assumes nobody leaves. Run a break-even check by dividing your monthly savings by the gross profit from one regular customer per month. That tells you how many customers you can lose before the program stops paying off.
Program terms: some cash discount programs are bundled with leased terminals, monthly fees, or a processing rate higher than interchange-plus pricing would be. Interchange is the card-issuing bank's cut, assessments go to the card brands, and the markup and per-item fees go to your processor. You still pay all of them; your customers just fund more of it. Compare total monthly cost, not the 'zero processing fees' headline.
Underwriting and channel: switching processors or programs usually means a new application. Depending on your risk profile, that can bring holds on early deposits or a reserve. Online and phone orders have no cash option, so a cash discount doesn't translate well there. For B2B invoicing, ACH is often the lower-cost alternative to steer customers toward. Whether sales tax applies to the posted or the discounted price is a question for your tax advisor.
Run your own numbers in 15 minutes
Pull your last three processing statements. Divide total fees by total card volume to get your effective rate. Note your credit versus debit split, your average ticket, and the share of sales you take in cash. Use the three-month average so one unusual month doesn't skew the result.
Plug those figures into the formula above, or into the comparison tool, and test both an exact-recovery markup and a rounded one. Then check the result against your margins and how price-sensitive your customers are.

Frequently asked questions
What percentage should I use for a cash discount program?
Start from your own effective rate, not a number other businesses use, and gross it up: rate ÷ (1 − rate). Add the per-transaction fee if your tickets are small. Then confirm the card brand rules and your state's rules before settling on a figure.
Does a cash discount program eliminate my processing fees?
No. You still pay interchange, assessments, and your processor's markup on every card sale. The program shifts that cost to card-paying customers through a higher posted price. Fees on tips, refunds, and chargebacks can still land on you.
Is a cash discount program the same as dual pricing?
They are closely related. Dual pricing displays both a cash price and a card price, while a cash discount program posts the card price and discounts cash at the register. Display and disclosure requirements vary, so confirm them with the card brands and your state.
Is a cash discount program allowed in my state?
We can't tell you that. Rules vary by state and by card brand and change over time. Confirm with the card brands, your state, and ideally an attorney before you change your pricing.
Can I run a cash discount program on online sales?
Generally it isn't a natural fit, because online customers can't pay cash. Businesses that invoice often encourage ACH or eCheck payments instead, since those typically cost less to process than cards.
How we put this together
The formulas here are standard pricing arithmetic: grossing up a price so a percentage fee charged on the full ticket nets the original amount. All dollar figures are made-up examples. The 2.75% restaurant effective rate, the 2.7% + $0.10 coffee example, the 1.75% debit cost, and the 60/40 credit/debit split are assumptions drawn from published industry ranges and the stated assumptions in our comparison tool, not TouchSuite quotes. Your actual interchange depends on card type, how the card is accepted, and the card brands' published interchange tables, which change periodically. Verify these on your own statement: total fees divided by card volume (your effective rate), your credit versus debit split, any per-transaction and monthly fees, and how refunds and tips are handled. Card brand rules on surcharging, caps, and disclosure have changed several times in recent years, and state rules vary. Check the current rules with the card brands and your state as of the date you read this. Estimates are based on published industry averages and are not a quote.
