Core formulas
The formulas to keep straight
card fee per sale = sale price x fee rate + fixed feeprofit after card fee = sale price - product cost - card feedaily card fees = card fee per sale x card salesbreak-even units = fixed event cost / profit after card feeShould you accept card payments at craft fairs?
Most craft sellers should accept cards if the product margin can absorb the fee. Buyers often expect card, tap, or wallet payments, and refusing cards can lose higher-value orders.
The fee still belongs in the booth math. On a $35 sale, Square's US card-present rate of 2.6% + $0.15 produces a $1.06 fee.
Square's fee was checked from its US fee page on July 3, 2026. Stripe pricing is country-routed, so sellers should verify Stripe in their own account country before using a rate.

| Sale amount | Fee | Net before product cost |
|---|---|---|
| $10 | $0.41 | $9.59 |

Should you offer cash discounts at craft fairs?
Cash discounts can work, but they are often less clean than pricing the fee into the product. A small discount can slow checkout and train buyers to ask for lower prices.
If a $35 card sale costs $1.06 in processing, a $1 cash discount roughly matches the processing fee. A $5 cash discount gives away more than the fee.
Keep the booth simple. Clear pricing and fast payment usually beat complicated discount rules.
Cash discount check, checked July 3, 2026
| Choice | Seller gives up | Comment |
|---|---|---|
| No cash discount | $0 | Fee is priced into margin |
| $1 cash discount | $1 | Close to the $1.06 card fee on $35 |
| $5 cash discount | $5 | Far larger than the card fee |
| Bundle discount | Depends on cost | Can raise average order value |
How should card fees be priced into craft fair products?
Card fees should be included in expected unit profit before the event. The cleaner method is to price for an average payment mix instead of changing the price at checkout.
If most buyers pay by card, use card fees in the break-even calculator. If only some buyers pay by card, use a blended card cost based on expected card share.
Do not rely on card surcharges unless you have checked the rules that apply to your location and payment provider.
- Use card fees in the default booth plan.
- Use cash as upside, not as the only profitable path.
- Train staff to keep checkout fast.
- Bring a backup payment method for weak signal or reader failure.

Worked examples
Examples you can compare against your own numbers
Example: card fee on a $35 sale
A seller uses a card-present rate of 2.6% + $0.15 on a $35 craft fair sale.
| Sale price | $35.00 | Buyer pays |
|---|---|---|
| Percentage fee | $0.91 | 2.6% of $35 |
| Fixed fee | $0.15 | Per transaction |
| Total card fee | $1.06 | Processing estimate |
| Net before product cost | $33.94 | Before materials, labor, and booth cost |
Takeaway: A single card fee is small. A full day of card fees should be part of the booth plan.

FAQs
Questions people ask before making the decision
Should I accept cards at a craft fair?
Yes, if your margin covers the fee. Cards can help buyers spend more, but the processing cost should be in your booth math.
What are Square fees at a craft fair?
As of July 3, 2026, Square's US fee page lists tap, dip, or swipe payments at 2.6% + $0.15. A $35 sale costs $1.06 at that rate.
What are Stripe reader fees at a craft fair?
Stripe pricing is country-routed, so use the rate shown for your own Stripe account country. Do not copy a rate from another seller without checking it.
Should I charge customers extra for cards?
The cleaner method is to build expected fees into prices. If you want a surcharge, check local rules and your payment provider terms first.
Is cash better than cards at craft fairs?
Cash avoids processing fees, but cards can increase checkout convenience. Price so the booth works even when most buyers pay by card.
How do I track craft fair card fees?
Export or record gross card sales, processing fees, refunds, and net deposits after the event. Compare that with your booth plan.
