Buy Calculator
What will this actually cost to own?
Estimate purchase, setup, running and repair costs for a period you choose. Cash, resale assumptions and your own time stay separate; a blank remains unknown, not zero.
Compare A and B
Check the periods and missing costs before comparing. An incomplete subtotal is not a cheaper total.
Calculation method & worked example
How this is calculated
Correction, October 17, 2026: this method now describes the inputs available in this form. Financing costs and downtime impact are not separate inputs here.
Enter the values you have. Money is calculated in decimal at full precision and rounded only when shown. A missing required input means there is no total; an unknown optional category produces an incomplete subtotal that names what is missing. A zero denominator returns "not calculable" with the reason.
Calculate lost business separately in Downtime impact. This form has no separate financing-cost or downtime-impact input. If you combine results in your own records, keep business impact on its own line and check for expenses or recoveries counted in both tools.
initial_costs = purchase + delivery + installation
annual_net_cash = electricity + water + consumables
+ paid_maintenance + repairs − recoveries
cash_cost = initial_costs + years × annual_net_cash
cash_after_assumed_resale = cash_cost − assumed_resale
time_value = years × annual_unpaid_hours × hourly_rate
economic_view = cash_after_assumed_resale + time_value
cash_per_use = cash_cost ÷ uses_in_same_periodFictional worked example: $12,000 initial cost + 3 × $2,600 annual net cash = $19,800. Subtracting $2,000 assumed resale gives $17,800. Adding 90 unpaid hours × $25 gives a $20,050 economic view. Cash per use at 900 uses is $22. These inputs are illustrative, not product predictions.
What's kept apart
The resale field is an assumption, shown separately from cash outlay. Unpaid owner time has its own line before it enters the economic view. This form does not collect loan principal or depreciation.
What's not in here
No industry average, failure rate, useful-life assumption or energy figure. Every number comes from you. The three-year example is fictional and unrelated to any real owner, business or manufacturer.
