What is a base wage rate?

The base wage rate is the fixed hourly amount an employee is paid before overtime, bonuses, differentials or tips. It is the starting point for pay, but not always the rate overtime is figured on.

In shortA base wage rate is the agreed hourly rate for an employee’s regular work, written in the offer letter or pay record, before any additions. It must be at least the applicable minimum wage, which is $7.25 an hour under federal law and higher in many states and cities. The most common payroll error tied to it is using the base rate to calculate overtime when the employee also earned a nondiscretionary bonus or differential that week. For hourly employees with no extra pay, the hourly rate is the regular rate (29 CFR 778.110(a)), but once such pay is added, the regular rate rises above the base.

Base rate vs. regular rate

Two rates that are easy to confuse
Base wage rate Regular rate
What it is The agreed hourly rate All includable pay for the workweek divided by hours worked
Changes week to week? No, until a raise Yes, when bonuses or differentials vary
Used for Straight-time pay, offer letters, pay bands Overtime premium under the FLSA

29 CFR 778.110(b) shows the method: add a production bonus to straight-time earnings, divide by total hours, and that is the regular rate. For a full walk-through, see the regular rate of pay guide.

The bonus raises the rate that overtime is figured on, not only the total pay.

Worked example: a $90 bonus and 45 hours

Base $18, plus a production bonus

A packer earns a base wage rate of $18 an hour and works 45 hours in a workweek. She also earns a $90 production bonus that week.

Straight time: 45 hours times $18 is $810. Add the bonus: $900. Regular rate: $900 divided by 45 hours is $20. Overtime premium: half of $20, or $10, for each of the 5 overtime hours, which is $50. Total pay: $950.

If payroll had figured overtime on the base rate only, it would pay $810, plus 5 times $9 in premium, plus the $90 bonus, or $945. That is $5 short for one person in one week, which becomes real money across a crew and a few years of back pay.

What the base rate does decide

Mistakes that are specific to base wage rates

Shift differentials and the base rate

A shift differential, such as $1.50 more per hour for night hours, is usually paid on top of the base wage rate rather than changing it. The base stays the agreed rate for the job, and the differential is added for the hours that qualify. For overtime, the differential is part of the regular rate, the same as a nondiscretionary bonus.

Keep the base and the differential as separate lines in payroll. It makes raises simpler, because a raise changes the base and the differential stays the same, and it makes the overtime calculation easy to check.

Second example: a night differential in an overtime week

A warehouse associate has a base wage rate of $18 an hour and works 45 hours in a week, 20 of them on nights with a $1.50 differential.

Straight time is 45 x $18 = $810, plus 20 x $1.50 = $30 in differential, for $840. The regular rate is $840 / 45 = $18.67. The overtime premium is half of that, about $9.33, for 5 hours, or $46.67. Total pay is $886.67. Overtime figured on the $18 base alone would give a premium of $45, about $1.67 short.

Run the two-number checkIn any week with a bonus or differential, payroll should show two numbers per employee: the base rate and the regular rate. If they are the same in a week with extra pay, the overtime calculation is probably wrong.

Questions people ask

Is the base wage rate the same as the regular rate?

Only when there is no other includable pay. Once a nondiscretionary bonus or differential is earned in a week, the regular rate for overtime is higher than the base rate.

Can the base wage rate be below minimum wage for tipped employees?

Federal and many state rules allow a lower cash wage for tipped employees with a tip credit, under conditions, while others do not. Check the rule for your state.

Is base pay the same as gross pay?

No. Gross pay includes overtime, bonuses and other earnings on top of base pay, before deductions.

What is the federal minimum wage?

$7.25 an hour. Many states and cities set a higher minimum, and the higher one applies.

Does a shift differential change the base wage rate?

Usually not. The differential is added on top for qualifying hours, and it is included in the regular rate when calculating overtime.

How should a change to the base rate be recorded?

In writing, with the new rate and the date it takes effect, so payroll applies it from the right workweek.
