The economics of low-ticket payments
Fixed fees become a larger part of a small transaction.
Calculate the fixed portion
For an illustrative 3% + $0.30 fee, a $5 payment costs $0.45, or 9%, before any other charges. At $100 the same rule costs $3.30, or 3.3%. These are arithmetic examples, not a provider quote.
Include your selling tools
A monthly platform plan spread over 10 sales is very different from the same plan spread over 1,000. Minimum payout fees can also dominate small transfers.
Evaluate product changes carefully
Bundles, annual billing or different payment methods may change the economics, but also change customer obligations and refunds. Compare a clearly specified scenario before changing your pricing.
The fixed fee at $5, $10 and $29
These are two hypothetical checkout quotes in the same currency, with no monthly charge. The arithmetic isolates ticket size; it does not compare the full service supplied by a processor and an MoR.
| Ticket | 2.9% + $0.30 | Effective rate | 5% + $0.50 | Effective rate |
|---|---|---|---|---|
| $5.00 | $0.45 | 9.00% | $0.75 | 15.00% |
| $10.00 | $0.59 | 5.90% | $1.00 | 10.00% |
| $29.00 | $1.14 | 3.93% | $1.95 | 6.72% |
For a $5 sale, the $0.30 fixed component alone is 6% of revenue. For a $29 sale it is about 1.03%. Compare a quiet month and a busy month before paying for a lower percentage rate. Bundling changes the customer offer as well as the fee math.
