Compare equipment costs with paid usage and the extra income it can generate. Start with rental contracts, asset records and maintenance logs. Each example below uses hypothetical values you can replace.
Which calculator should you use?
| Tool | What it answers | What to check |
|---|---|---|
| Rental Day Price Floor | Recover asset ownership costs across realistic paid rental days. | Use paid days rather than calendar days. Enter financing, maintenance and depreciation consistently. |
| Equipment Investment Payback | Estimate the simple payback of an equipment purchase. | It only estimates recovery time under constant net benefit. It does not compare all cash flows or investment risk. |
These tools answer different questions and may use different units. Choose the tool that measures what you need; a larger result does not necessarily mean a better outcome.

Show example inputs and result
| Equipment and setup cost | 15,000 |
|---|---|
| Extra monthly contribution | 2,000 |
| Extra monthly running costs | 500 |
Result: 10 months.
