What Square costs per year, worked out
Square is the simplest pricing in UK card payments: a £19 + VAT reader, 1.75% flat on every in-person card, no contract, no monthly fee. Simple is not the same as cheap at every volume, and the table shows where the flat rate starts costing real money.
| Monthly card sales | Transaction fees/yr | Fixed costs/yr | Total/yr |
|---|---|---|---|
| £1,000 | £210 | £0 | £210 |
| £2,000 | £420 | £0 | £420 |
| £5,000 | £1,050 | £0 | £1,050 |
| £10,000 | £2,100 | £0 | £2,100 |
How the sums work
Yearly transaction cost is monthly card sales × 12 × 1.75%. The flat rate is Square's strength and its ceiling: at £5,000 a month it costs £1,050 a year against £720 at Dojo's published 1.2% (under £100,000 annual card turnover), and the gap widens with volume. Below roughly £2,500 a month the simplicity usually wins; above it, compare against a lower published or negotiated rate before defaulting to flat. Keyed and online payments cost more than the in-person rate.
