Inputs
Calculations stay in this browser unless you explicitly save or share.
Estimate straight-line depreciation, book value, hourly depreciation, and replacement reserve for compact equipment ownership planning. Results update automatically as inputs change.
Annual depreciation = (purchase price - expected resale value) / useful life. Hourly depreciation = annual depreciation / annual billable hours.
Use this calculator to account for the value a machine gives up while it works, even when there is no monthly payment left.
This tool is best for including machine value loss in cost per hour. Its primary decision is how much value loss belongs in each year and each billable hour of machine work. Review pricing paid-off equipment too cheaply, ignoring replacement cost, overestimating resale value, and failing to reserve for the next machine before relying on the result.
A $65,000 machine with $25,000 expected resale over 6 years loses about $6,667 per year, or $9.52/hour at 700 billable hours.
Use conservative resale value and realistic annual billable hours so paid-off equipment is not priced like it is free.
Keep the final scope, assumptions, exclusions, allowances, change triggers, and post-job results with the estimate so future defaults are supported by evidence.
No. It is a planning checkpoint. Walk the site, confirm scope and access, verify current costs, and apply contract, permit, tax, utility, safety, and professional requirements.
Only an explicit Save stores inputs in this browser's localStorage. Share places inputs in the URL hash. The calculator does not send them to Equipment Rate Calc.
Use market prices as a reasonableness check after calculating your own cost, scope, utilization, risk, and margin.
