No scenarios yet. Save the current inputs to compare them side by side.

Formulas: investment = number of devices × device price. Sold hours = devices × hrs/day × days × sellable rate. Revenue = accepted hours × price. Collection cost = recorded hours × cost/hr. A month is 4 weeks, so 6 days a week = 24 days a month. Net profit = revenue − collection cost − all device purchases in the horizon (devices are bought again when they wear out). ROI = net profit ÷ investment. Payback = when cumulative profit first covers the device spend. The starting figures are examples; replace them with your own.
