Reverse Overtime Rate Calculator
Standard Formula
Base Rate = Overtime Rate ÷ Multiplier (default 1.5)
Back-calculates your regular straight-time hourly rate from an overtime rate listed on your paystub.
How Reverse Overtime Rate Calculator Works?
The Reverse Overtime Rate Calculator works by dividing an overtime rate by its multiplier to find the regular base rate. Enter $45.00 at 1.5× and the tool returns a $30.00 base rate.
1Enter the overtime rate
Type the overtime hourly rate shown on a paystub, offer letter or job posting.
2Confirm the multiplier
Keep 1.5 for time and a half, or enter 2.0 for double time or another contract factor.
3Read the base rate
The calculator divides the overtime rate by the multiplier. $45.00 ÷ 1.5 = $30.00 per hour.
4Check the weekly value
The tool multiplies the base rate by 40 hours to show standard weekly pay, $1,200.00 at $30.00 per hour.
Reverse Overtime Rate Calculator Formula
The Reverse Overtime Rate Calculator formula is Base Rate = Overtime Rate ÷ Multiplier. The default multiplier is 1.5.
Base rate
Base Rate = Overtime Rate ÷ Multiplier
Premium per hour
Premium = Overtime Rate − Base Rate
Standard 40-hour week
Weekly Pay = Base Rate × 40
- Overtime Rate
- The known overtime wage in $/hr.
- Multiplier
- The factor used to build the overtime rate (1.5 or 2.0).
- Base Rate
- The regular straight-time wage that the tool solves for.
Worked example: a $39.75 overtime rate
Base Rate = $39.75 ÷ 1.5 = $26.50 per hour.
Premium = $39.75 − $26.50 = $13.25 per overtime hour.
Standard week = $26.50 × 40 = $1,060.00.

| $60.00 | $40.00 | $30.00 | $1,600.00 | $83,200.00 |
The annual column uses 2,080 hours (40 hours × 52 weeks) at the 1.5× base rate.
What is Reverse Overtime Rate Calculator?
A Reverse Overtime Rate Calculator is a back-calculation tool that finds the regular hourly wage hidden inside an overtime rate. The tool runs the time-and-a-half formula in reverse.
Job ads for nurses, drivers and warehouse staff often quote the overtime rate ("$45/hr OT") to attract applicants. Dividing by 1.5 reveals the base wage that pays the first 40 hours of each week.
The result is only as accurate as the multiplier. A posting that quotes a double-time rate needs 2.0 in the multiplier field, not 1.5.
What are the uses of Reverse Overtime Rate Calculator?
There are 4 main uses of the Reverse Overtime Rate Calculator when only the overtime figure is known.
Job posting analysis
Applicants convert an advertised overtime rate into the real base wage.
Paystub decoding
Workers whose stub lists only an OT rate recover the regular rate for budget planning.
Regular rate audits
Payroll teams confirm that an overtime rate code equals exactly 1.5× the base code.
Salary conversion
Contractors turn an overtime quote into a 40-hour weekly or 2,080-hour annual figure.
