Choose a term for the schedule, not the project label
Even for a two-week project, check the monthly rate
Billing terms aren’t recommendations for how long to use the machine. A two-week project doesn’t automatically mean two weekly terms. Compare combinations that cover your schedule, then decide whether to leave time for follow-up fixes.
Daily to weekly: check day 3 for both tiers
For M4, 54.6 ÷ 20.2 ≈ 2.70; for M4 Pro, 160 ÷ 59.3 ≈ 2.70. Rounding up, once you need the machine for 3 consecutive days, one weekly term costs less than three daily rentals.
For just 1 or 2 days with no confirmed work afterward, daily billing is straightforward. For 3 to 7 consecutive days, compare the monthly rate too—weekly isn’t always the cheapest option.
Daily to monthly: day 6 for M4, day 5 for Pro
For M4, 101.1 ÷ 20.2 ≈ 5.00, but the actual figure is slightly above 5, so the break-even point is day 6. For M4 Pro, 296.3 ÷ 59.3 ≈ 5.00, but the actual figure is slightly below 5, so the break-even point is day 5.
This compares the monthly price with the accumulated daily rate; it doesn’t mean you should ignore weekly billing. For a short rental, compare daily, weekly, and monthly combinations that cover your schedule.
Before a second weekly term, check the monthly rate
For both tiers, 2 × weekly price > monthly price. At 7 days per week, once you reach day 8, don’t renew for a second week automatically—check whether monthly billing is a better fit.
For a two-week delivery plus a few days of fixes, the monthly term is usually worth pricing first. If there’s a long gap in the middle of the project, you can rent in separate periods, but account for setup and data-migration time.
For three consecutive months, consider quarterly billing
For both tiers, 2 × monthly price < quarterly price < 3 × monthly price. If you only need two full monthly terms, start with monthly billing. Consider quarterly billing when you know you’ll need a third consecutive month.
Compared with the accumulated daily rate, quarterly billing crosses the break-even point on day 14 for both tiers. Monthly billing is still cheaper at that point, so a two-week project shouldn’t be steered toward a quarterly term. Check all the other options when comparing billing periods.
