ROI calculator
Payback period, arithmetic shown
Gross revenue against capital cost. Consumables, staff time, room cost, servicing and finance interest are not included, so read the result as a ceiling.
Payback period
5.1months
12 × £95 = £1,140 / week
£1,140 × 52 ÷ 12 = £4,940 / month
£24,950 ÷ £4,940 = 5.1 months
Gross revenue only. This excludes consumables, staff time, room costs, servicing and finance interest, so treat it as an upper bound rather than a forecast.
