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.

The working

Whole weeks bill at the week rate; the leftover days bill at the day rate but never add up to more than one extra week; and a whole 28-day cycle never costs more than the 28-day rate. That is the rule, applied one day at a time.

What checkout will quote you

Our pricing service couldn’t be reached just now, so there’s no checkout figure to show. The rate table above is unaffected — it’s the operator’s published card.

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.
