Rest Day Overtime Calculator

What rest day work means

Rest day work generally means work performed on a day that would normally be a scheduled day off. In everyday searches, users may describe it as Sunday work, weekend work, a sixth day, a seventh day, or work on a regular rest day. The exact meaning depends on the workplace, jurisdiction, and policy.

This calculator does not assume one universal rest-day rule. Instead, it lets you enter the rest-day multiplier you want to model. Use regular rate, 1.5x, 2x, or a custom multiplier based on the policy or rule you are reviewing.

Rest day pay versus overtime pay

Rest day pay is a premium connected to the day worked. Overtime pay is a premium connected to qualifying overtime hours. A rest day can be paid at a premium even when a weekly overtime threshold is not crossed, and weekly overtime can apply even if the extra hours were not on a rest day.

The calculator estimates regular workweek pay, rest day pay, weekly overtime hours, and any additional overtime premium. Keeping those lines separate helps you see whether the total is driven by the day premium, the weekly threshold, or both.

U.S. federal weekend and rest-day nuance

Under the FLSA, extra pay is not required simply because work is performed on Saturdays, Sundays, holidays, or regular rest days unless overtime hours are worked on those days. For many U.S. federal examples, the key overtime trigger is hours worked over 40 in a workweek for covered nonexempt employees, with exemptions and special rules possible.

That federal nuance does not erase more generous employer policies, union agreements, state rules, local rules, public-sector rules, or non-U.S. labor systems. In some countries, rest days are treated much more specifically than under U.S. federal law. Use the custom multiplier to model the rule you actually need to compare.

Rest day overtime formula

If rest day hours count toward weekly overtime, the calculator adds them to regular workweek hours for the threshold test. If not, it tests only the regular workweek hours.

The overtime premium is separate from the rest-day multiplier. If your policy says one premium replaces another instead of stacking, enter the assumptions that best match that policy.

Regular workweek pay = Regular workweek hours x Hourly rate
Rest day pay = Rest day hours x Hourly rate x Rest day multiplier
Weekly overtime hours = Counted hours - Weekly overtime threshold
Overtime premium = Weekly overtime hours x Hourly rate x (Overtime multiplier - 1)
Estimated total pay = Regular workweek pay + Rest day pay + Overtime premium

Example with Sunday rest day work

Suppose a worker earns $24 per hour, works 38 regular workweek hours, and then works 8 Sunday rest-day hours. If the rest day is paid at 1.5x and rest-day hours count toward a 40-hour weekly threshold, counted hours are 46, so 6 hours are above the threshold. The calculator adds rest-day pay and the separate overtime premium estimate.

Why results vary by jurisdiction

Rest-day rules vary widely. Some systems focus on weekly overtime only. Others have special Sunday rules, seventh-day rules, holiday rules, required rest periods, or different treatment for salaried employees and hourly employees. Industry rules can also matter.

Because the calculator cannot identify the rule that applies to a specific worker, it is built as an assumption-driven estimate. Review official sources, local rules, contracts, and employer policies before relying on a rest-day pay estimate.
