Borrow, Rent, or Buy: How to Decide for Any Tool

You need a circular saw for one weekend. Do you ask your neighbor, drive to the rental counter, or drop $150 on one you might not touch again for a year? Each option costs something different in money, time, and hassle. This page breaks down when each path makes sense so you can stop overthinking it.

What Each Option Means

Borrowing (Peer-to-Peer)

You ask someone you know. With FriendsWithTools, that means sending a borrow request to a friend or group member who owns the tool you need. They approve it, you pick it up, you return it when you're done. No money changes hands. The cost is social: you're asking a favor, and you're responsible for the tool while you have it.

Borrowing works because most tools sit idle 95% of the time. A miter saw might get used 10 weekends a year. The other 42 weekends, it collects dust. Sharing access to that saw costs the owner nothing and saves the borrower real money.

Renting (From a Store)

Home Depot, Sunbelt, United Rentals, and local shops all rent tools by the hour, day, or week. You pay a flat rate, pick it up, use it, and return it. Some charge a deposit. Most require a credit card on file. You get a maintained tool with no social obligation, but the clock is ticking the entire time you have it.

Rental stores stock heavy equipment and specialized tools that most people don't own. Concrete saws, plate compactors, scaffolding. For that category of tool, rental is usually the only realistic option besides buying.

Buying (Owning Outright)

You pay once and keep it forever. You can use it whenever you want, modify it, lend it out, or sell it later. The tradeoff is upfront cost, storage space, and maintenance. A tool you own needs occasional blade changes, battery replacements, and a place to live in your garage or shop.

Cost Comparison: Circular Saw Example

Here's what the same job (cutting lumber for a deck frame) costs under each model:

• Borrow from a friend: $0 out of pocket. You might bring over a six-pack or return the favor next month. Total real cost: minimal.
• Rent from Home Depot: $30/day for a 7.25" cordless circular saw. A two-day deck project runs $60 plus tax and the drive to/from the store.
• Buy a Ryobi PBLCS300B: $80 bare tool (you already own ONE+ batteries). You now own a saw you can use for the next decade.
• Buy a DeWalt DCS570B: $150 bare tool. Higher-end option. Same ownership math: one rental season of use pays for itself.

The breakeven point for buying vs. renting is usually 2-3 uses. If you'll use a tool more than twice in a year, buying saves money over renting. If you'll use it once and never again, borrowing or renting wins.

Decision Framework

Ask yourself three questions:

How Often Will You Use It?

• Once: Borrow it. This is the strongest case for peer-to-peer sharing. You avoid spending money on something that will sit unused.
• 2-4 times a year: Borrow if you can, buy if you'll keep using it for multiple years. Renting 4 times a year at $30/day adds up to $120, which is already close to buying a mid-range version.
• Monthly or more: Buy it. At this frequency, you need it available on your own schedule without coordinating with anyone else.

Do You Need It Today?

• Borrowing depends on someone else's schedule. If your friend is out of town, you're stuck.
• Renting depends on store inventory. Popular tools (concrete mixers, tile saws) sell out on weekends.
• Owning means it's in your garage right now. No coordination, no waiting.

Does Storage Cost You Anything?

A cordless drill fits in a drawer. A table saw takes 10 square feet of floor space. If you're in an apartment or a house with a small garage, storing large tools costs you real living space. Borrowing heavy equipment you rarely use keeps your space clear.

This is where borrowing has the biggest advantage over buying for occasional-use tools. The saw goes back to someone who has space for it.

Per-Category Verdicts

Drills and Drivers

Buy. You'll use a drill more often than you think (hanging shelves, assembling furniture, minor repairs). A basic cordless drill costs $50-80 and lasts years. This is a tool worth owning. See our full borrow-or-buy breakdown for specifics.

Saws (Circular, Miter, Reciprocating)

Depends on the project. A circular saw is worth owning if you do any regular woodworking or home improvement. A miter saw is bigger and more specialized. Borrow a miter saw for a single trim job. Buy one if you're doing multiple rooms of baseboard or building furniture regularly.

Sanders and Grinders

Random-orbit sanders are cheap enough to own ($40-60). Angle grinders are worth owning if you work with metal at all. For a one-time refinishing project, borrowing a belt sander or detail sander makes sense.

Specialty and Heavy Equipment

Rent or borrow. Concrete mixers, plate compactors, demolition hammers, tile saws. These are expensive, heavy, and used a few times over a lifetime for most people. Unless you're a contractor, there's no reason to own one.

Outdoor and Yard Tools

Chainsaws, pressure washers, and pole saws get used seasonally. If you have a yard, a basic chainsaw is worth owning for storm cleanup and firewood. A pressure washer gets used twice a year at most. Borrow it.

The Borrowing Advantage Nobody Talks About

When you borrow a tool from someone experienced, you often get advice with it. Your neighbor who owns the miter saw knows which blade to use for crown molding. The friend with the tile saw can tell you how much water to run. That knowledge transfer doesn't come with a rental from a big box store.

Borrowing also means you can try a tool before committing to a purchase. Use your friend's DeWalt drill for a weekend. If you like how it feels and you're already invested in the 20V MAX battery system, you know what to buy. If you prefer the lighter Makita you tried at someone else's shop, you saved yourself $150 and a return trip.

When Renting Still Wins

Rental stores serve a purpose that borrowing and buying can't match:

• You need a tool nobody in your circle owns (concrete core drill, stump grinder)
• The job is dangerous and you want a recently-inspected, properly-maintained machine (chainsaws, demolition equipment)
• You need it for a single day and want zero obligation afterward
• You're doing a job that wears out tools fast (demolition, large-scale grinding) and don't want to destroy your own gear
