Here is the short answer. If you will use a tool or piece of gear fewer than five times a year, renting is usually the better deal. If you will use it more often than that, buy it. Everything below is the reasoning, so you can adjust the rule for your own situation.
Where the rule comes from
Most tools and gear in the categories people ask about, pressure washers, carpet cleaners, tile saws, tents, paddleboards, sit in a similar price band: the daily rental rate is somewhere between five and ten percent of the purchase price.
Take a concrete example in Canadian dollars. Say a mid range electric pressure washer costs about $350 to buy, and renting one nearby costs about $30 a day. That is roughly nine percent of the purchase price per rental day. If you use it three times a year, you spend $90 a year renting. It would take four years of that to reach the sticker price, and that ignores everything else ownership costs.
That example is worked all the way through, against real Canadian prices and all four ways to get one, in the pressure washer post.
At five or more uses a year the math flips within a season or two, and the convenience of owning starts to be worth paying for.
The costs the sticker price hides
Purchase price is the visible number, but it is not the whole cost of owning:
- Storage. A pressure washer, a shop vac, and a tile saw take real space. If you live in a condo, storage is often the deciding factor before money is.
- Depreciation. Gear loses value whether you use it or not. A tool used twice and sold three years later returns a fraction of what you paid.
- Maintenance. Pumps need to be winterized, blades need replacing, batteries age even in a drawer.
- The upgrade cycle. The model you buy today is the model you are stuck with. Renters get whatever is current.
None of these show up when you compare a $350 purchase to a $30 rental, and all of them favour renting for anything you use occasionally.
A worked comparison
Illustrative numbers for common items, using typical Canadian retail prices and the kind of daily rates you see on rental marketplaces:
| Item | Typical buy price | Typical rental per day | Break even point |
|---|---|---|---|
| Electric pressure washer | $350 | $30 | about 12 rental days |
| Carpet cleaner | $300 | $35 | about 9 rental days |
| Four person tent | $400 | $20 | about 20 rental days |
| Tile saw | $450 | $40 | about 11 rental days |
| Paddleboard | $600 | $35 | about 17 rental days |
Read the last column as a calendar, not a count. Twelve rental days at three uses a year is four years. If your honest usage estimate gets you to the break even point within a year or two, buy. If it takes half a decade, rent.
The tent row is the one people argue with, so it gets its own post. Renting your first camping kit is not a compromise, it is the correct order of operations, and every way to rent camping gear in Toronto prices the shops, the gear libraries, the park outfitters, and the neighbours against each other.
When buying still wins
The rule has exceptions, and they matter:
- You use it constantly. Five uses a year is the threshold, and plenty of tools clear it easily. Nobody should rent a drill.
- Timing is critical. If you need a sump pump the night your basement floods, availability beats price.
- It is personal equipment. Boots, helmets, anything fitted to your body is usually worth owning once you know you will keep using it.
- The used market is strong. If you can buy used at half price and resell for most of it later, ownership gets cheaper than the table above suggests.
How to run the numbers for your own case
Three questions settle almost every rent or buy decision:
- How many days a year will I honestly use this?
- What does a day of renting it cost near me?
- Where would I put it?
For the second question, browse what people near you are renting out to see real asking prices. Before you plan anything around a particular app, it is worth knowing which rental platforms actually operate in Canada, because several of the ones still recommended online stopped existing years ago. If you already own the item and are wondering about the other side of the trade, the what is it worth estimator gives you a rental price estimate for it, and the hosting guide covers what listing involves.
The point of the rule is not that owning is bad. It is that ownership should be earned by frequency. For everything you use twice a year, someone a few streets away already owns one, and it is sitting idle.
