When is it cheaper to rent a Dewalt Pressure Washer 4000 PSI by the week than by the day?

From day 6. 6 days at the $90 day rate would be $540, but the weekly rate caps it at $450.

When is it cheaper to rent a Dewalt Pressure Washer 4000 PSI on the 28-day rate?

From day 18. At that point the week-and-day composition reaches the $1,200 28-day rate, and the price stops climbing for the rest of the cycle.

Break-even duration

Equipment rents on three rates — a day rate, a week rate and a 28-day rate — and the cheapest one changes as the job runs long. This finds the two days where it changes, on a real listing’s real published rates.

Pick a listing

The numbers come from one operator’s published rates, so the tool needs to know whose.

Where these numbers come from

The rates are the operator’s own, read live from their listing. The arithmetic is the same best-price billing engine that produces 2Quip invoices — not a second copy written for this page — run on the industry-standard terms: a 28-day cycle, whole weeks at the week rate, leftover days at the day rate capped at one more week.

An operator can agree different terms on an individual rental, and a long rental bills per 28-day cycle rather than in one lump. So treat this as what the rate card says, and the operator’s quote as what you are agreeing to.
