How it is calculated

The tool compares the purchase price with total rent over the period you plan to use the machine: rent total = R × M and difference = B − R × M, where B is the buy price, R the monthly rent and M the number of months, all in US dollars. A positive difference means renting costs less than buying for that period; a negative one means the rent already exceeds the price. The break-even point is B ÷ R months. The calculation is deliberately simple: it ignores resale value, maintenance, insurance, financing interest, tax effects and rent increases, so add those to the figures yourself if they matter.

Worked example

A contractor can buy a mini excavator for $24,000 or rent it for $1,100 a month, and needs it for 18 months. Step 1: rent total = 1,100 × 18 = $19,800.00. Step 2: difference = 24,000 − 19,800 = $4,200.00. The tool shows $19,800.00 as the rent total and a $4,200.00 difference in favour of renting. Break-even is 24,000 ÷ 1,100, about 21.8 months, so at 30 months renting would cost $9,000.00 more than the price.

Common mistakes

  • Treating the difference as the full verdict: it ignores what the machine could be sold for afterwards, which can tip a close call towards buying.
  • Forgetting running costs that only owners pay, such as servicing, storage and insurance, or that a rental price may already include them.
  • Entering the weekly or daily rate in the monthly rent field; the result is then many times too small or too large.
  • Using the months you hope to need the equipment instead of a realistic figure — a machine that sits idle still costs money once bought.
  • Reading a negative difference as a loss; it means the cumulative rent has passed the purchase price.

About this calculator

Deciding whether to buy or rent equipment comes down to comparing two different cost structures over the same time horizon: buying means a large upfront purchase price, which may be partly offset by whatever salvage or resale value remains at the end, while renting means smaller recurring payments that add up over time but leave nothing owned afterward.

Below a certain usage period, renting is usually cheaper because the equipment sits idle less and there's no ownership risk; beyond that break-even point, buying typically wins because cumulative rental payments overtake the net cost of ownership. This calculator compares the purchase price against the monthly rent multiplied by the number of months you specify, and shows the difference. It does not account for resale value, so to include it, subtract the amount you expect to recover from the purchase price before entering it. It is useful for construction firms, event companies, medical practices, and any business deciding whether a piece of equipment is used often enough to justify owning it outright.

    Resale value is the missing piece here. If you expect to sell the machine afterwards for 5,000, subtract that from the buy price before typing it in, and the difference then shows the true cost of owning for your period. Without it, buying looks worse than it will be on long jobs. The break-even month is the buy price divided by the monthly rent. What do you expect to recover at resale, and does your rental price include maintenance?
