What the washington overtime calculator works out
Most US states follow the federal rule: overtime after 40 hours in a week. Washington sets overtime by the workweek, with no daily limit. This calculator adds up one week of hours and pays the hours past 40 at time and a half.
How it is calculated
Add up the week
Add the hours worked on each day of the workweek. Every day counts the same; there is no daily limit.
Split at the weekly limit
The first 40 hours are regular hours. Hours past 40 in the week are overtime at time and a half.
Worked example
At $20 an hour: five 8-hour days, then 5 hours on Saturday and 3 on Sunday, make 48 hours. The first 40 are regular, the last 8 are overtime. Pay is 40 x $20 = $800, plus 8 x $30 = $240: $1,040 for the week.
Know the hours before you pay them
Wrkbase records hours as people work: attendance logs sign-in, breaks and sign-off for each day, and a task timer starts when a task moves to In progress. Both are on the Free plan, for up to 5 people.

No, except on certain public works projects. Washington counts hours over 40 in a 7-day workweek, so a 10-hour day does not by itself trigger overtime.
Does this cover every case?

Does Wrkbase calculate overtime pay?
Daily overtime, yes, on the Team plan. Hours past a daily threshold you set are paid at one multiplier, 1.5 times by default. It does not apply weekly thresholds, double time or any state rule, so use this calculator for the full amount and add the difference to the pay run as a bonus.
