How the sum works
For each option the calculator adds what you pay up front, the monthly cost for every month, and the yearly cost for every year. It takes off what the thing is worth at the end, if you could sell it. If you add your own hours, they count at the hourly value you give. The option with the lowest total costs least over the years you choose. The Math tab shows every addition.
A worked example
A van on a lease costs $1,500 up front, $420 a month and $900 a year for insurance and service. Buying one costs $24,000, $1,400 a year, and you could sell it for $7,000 after 3 years. Over 3 years the lease costs $19,320 and buying costs $21,200, so the lease costs $1,880 less. Buying also needs $25,400 in the first 3 months, against $3,660 for the lease. These are example figures, not market prices; put in your own quotes.
What the numbers leave out
- Cash today. Two options can cost the same over 3 years while one needs far more money in the first months. The result shows the cash in the first 3 months for the cheapest option.
- Tax. Prices go in before tax. What you can reclaim or deduct depends on your business and country, so ask your accountant.
- Risk and fit. Who fixes it on a busy day, what happens if you stop early, and whether it fits the way you work.
