How to calculate time and a half

Time and a half means 1.5 times your regular hourly rate. If you earn $20 an hour, time and a half is $30 an hour. The formula is simple, but applying it correctly to actual paychecks involves several edge cases — bonuses, multiple rates, salaried employees, and state-specific rules. Here's how to do it right.

The basic formula

Time and a half = Regular hourly rate × 1.5

Examples:

When is time and a half required?

Under the Fair Labor Standards Act (FLSA), non-exempt employees in the US must be paid time and a half for any hours worked over 40 in a single workweek. Several states add daily overtime rules:

If you're salaried but non-exempt (earning under $43,888/year and not meeting duties test), you're still entitled to overtime — see exempt vs. non-exempt.

Worked example 1: simple hourly overtime

Sarah is a non-exempt employee earning $22/hour. Last week she worked 48 hours.

  1. Regular hours (up to 40): 40 × $22 = $880
  2. Overtime rate: $22 × 1.5 = $33/hour
  3. Overtime hours: 8 (anything over 40)
  4. Overtime pay: 8 × $33 = $264
  5. Gross weekly pay: $880 + $264 = $1,144

Worked example 2: time and a half with bonus

If your pay includes a non-discretionary bonus — meaning it's based on production, attendance, or performance metrics — the FLSA requires you to include the bonus when calculating the "regular rate" used for overtime.

Mike earns $20/hour and got a $200 production bonus for the week. He worked 50 hours.

  1. Total straight-time pay: (50 × $20) + $200 = $1,200
  2. Regular rate: $1,200 ÷ 50 = $24/hour (this is the "real" hourly rate)
  3. OT premium: $24 × 0.5 = $12/hour additional for OT hours (the half in time and a half)
  4. OT premium pay: 10 OT hours × $12 = $120
  5. Total gross: $1,200 + $120 = $1,320

Notice the bonus makes his effective overtime rate higher than just $20 × 1.5. The DOL settles millions in violations over employers excluding bonuses from regular rate.

Worked example 3: salaried non-exempt

Lisa earns a salary of $36,000/year ($692.31/week) but doesn't meet the FLSA duties test, so she's non-exempt. She regularly works 45 hours.

  1. Regular rate: $692.31 ÷ 45 = $15.38/hour
  2. OT premium: $15.38 × 0.5 = $7.69/hour (the half)
  3. OT premium pay: 5 OT hours × $7.69 = $38.45
  4. Total weekly pay: $692.31 + $38.45 = $730.76

For salaried non-exempt workers, the calculation is "half-time" added on top of the salary, not the full time-and-a-half rate. This is because the salary already covers the straight-time portion of OT hours.

Time and a half vs. double time

MultiplierNameWhen required
1.0×Straight timeNormal hours
1.5×Time and a halfFederal OT (40+ hrs/wk), most state daily OT
2.0×Double timeCalifornia after 12 hrs/day or 8 hrs on 7th consecutive day; some union contracts
2.5× or 3.0×"Triple time" or premiumSome union contracts for holidays

Common questions

Does time and a half apply to holiday work?

Under FLSA, no. Holiday pay is not federally required and is a matter of company policy. Many employers voluntarily pay 1.5× for working on Thanksgiving, Christmas, etc., but it's not legally mandatory.

Does my lunch break count toward the 40 hours?

Unpaid meal breaks (30+ minutes where you're fully relieved of duty) don't count toward hours worked. Paid rest breaks (5–20 minutes) do count.

Can my employer offer "comp time" instead of overtime pay?

For private-sector employees, no. Comp time (compensatory time off) is only legal for public-sector employees under FLSA. If you work for a private company, they must pay cash overtime.

Does time and a half include the regular rate, or is it on top of it?

"Time and a half" is the total rate, not an addition. If your regular rate is $20, time and a half is $30 (not $20 + $30 = $50). This trips people up. The "half" portion ($10 in this example) is sometimes called the "overtime premium."
