About this tool
Decide whether to rent or buy a tool from how often you use it, with the break-even number of usage days and total cost of each option.
This calculator answers the rent-or-buy question with a break-even figure: the number of usage days at which owning a tool becomes cheaper than hiring it. Renting is costed as a pure variable — day rate multiplied by usage days, plus the cost of each collection and return trip. Owning is costed as its fixed side: purchase price, annual servicing and storage, the capital tied up, less the resale value at the end of your horizon. Setting the two equal gives break-even days = net cost of owning divided by the effective cost of a rented day.

Turns the decision into one number: the usage days that tip it towards buying.
Each collection and return is charged, which is often what makes short hires expensive.
Owning is netted of what the tool sells for and charged for the money it locks up.
When your expected usage days exceed the break-even, which is the net cost of owning divided by the effective cost of a rented day. A tool costing ₹12,000 that resells for 40% and needs ₹500 a year of upkeep works out near ₹10,000 net over three years; against a ₹400 day rate plus a ₹150 trip, that is about 21 usage days. Below that, hiring wins.
Storage space, annual servicing, the consumables it needs, and the money tied up in it. The largest forgotten item is usually the opposite one: resale value. A working power tool sold second-hand recovers a real share of the price, and ignoring that makes ownership look worse than it is.
Almost always. Hire companies quote tiered rates where a week typically costs the equivalent of three to four days and a month a fraction more again, because their handling cost per hire is fixed. If you plan a hire of a week or longer, take the effective per-day figure from the weekly rate rather than multiplying the daily one.
Indirectly, through the resale percentage and the annual upkeep you enter. Set a lower resale figure and a higher upkeep for a tool you expect to work hard. For a specialised tool used a handful of days a year, the practical limit is often obsolescence and battery degradation rather than mechanical wear.
