How to Calculate Pay and Tax for Two Jobs

By Abdul Baseer · Published · Updated · 5 min read

In short

To calculate pay for two jobs, multiply each rate by its hours and add the results. Hours at separate employers are not combined for overtime; hours at the same or joint employers are. Then check the tax, because each employer withholds as if its job were your only one, which often leaves a bill.

How do you calculate pay for each job?

Multiply the hourly rate by the hours worked in the job. Hours and minutes are easier to enter as a clock figure, so 7:30 means 7.5 hours; to convert by hand, divide the minutes by 60, which makes 7 hours 45 minutes into 7.75 hours.

$23.50 an hour is 0.0065 a second and 0.3917 a minute, so divide any hourly wage by 3,600 for the per-second figure. Over a 40-hour week it is $940.00, $1,880.00 every two weeks, $4,073.33 a month and $48,880.00 a year, all before tax.

Do hours at two jobs add up for overtime?

Not when the employers are separate. Overtime is figured employer by employer, so 30 hours at $23.50 and 20 hours at $18.00 for two unrelated employers pay $1,065.00 a week with no overtime. If both jobs are with the same employer, or with related employers that share control of you, the hours are added together and the 50 hours carry 10 hours of overtime.

When the same employer pays two rates, the regular rate is the weighted average. Thirty hours at $20 and 20 hours at $30 give a regular rate of $24.0000, and the overtime premium for the extra 10 hours is $120.00. With an agreement made before the work, the employer may instead pay overtime at the rate of the job being worked during the overtime hours.

California daily overtime applies per employer. If you work there, run each job through the California tab of the overtime rate page instead of adding them up here.

How do you add up the weekly pay?

Add the pay from each job and any overtime premium. The weekly gross for the separate-employer example is $1,065.00. For a monthly or yearly view, multiply by 52 and divide by 12 or take the annual figure, but only after you have decided how many weeks each job really runs.

Double time pay is the hourly rate × 2 × hours. At $25 an hour that is $50, so 4 hours and 30 minutes (4:30) pays $225.00. Time and a half is the rate × 1.5 in the same way.

Why can two jobs mean a tax bill?

Each employer withholds as though its job were your only income. The second paycheck is therefore taxed starting from the bottom bracket again, at too low a rate for the combined income, and the shortfall appears when you file your return.

The usual fix is to tick Step 2 on your Form W-4 at both jobs, or to use the IRS Tax Withholding Estimator, which compares the two incomes and tells you what to enter. The calculator’s tax section shows the gap on the combined income with and without Step 2.

Social Security tax is a separate matter. Each employer withholds 6.2% up to the $184,500 wage base for 2026. If your combined wages pass that figure, you have paid too much, and the excess is credited back on your tax return.

What if one of the jobs is self-employment?

Then nobody withholds tax from that income. Net earnings from self-employment are subject to self-employment tax of 15.3%, which is the employee and employer shares of Social Security and Medicare together, and the income tax is usually paid through quarterly estimated payments.

The calculator here covers wage income only, with the standard deduction and no credits, so it will understate the tax on a mix of wages and self-employment. Use the IRS Tax Withholding Estimator for that case, and keep records of the hours and rates for both jobs so the figures on your return match your pay stubs.

How can you check the total against your stubs?

Add the gross pay from each stub for the same weeks and compare it with the calculator’s total. If the total is lower than your stubs, look for overtime, a bonus or a shift differential that was left out. If it is higher, check whether any of the hours were unpaid breaks or hours that were paid at a different rate.

Common questions

How do I calculate salary for two jobs?

Annualize each job (hourly rate × hours × weeks, or the annual salary), add them, and apply tax to the total. Set the jobs to different employers to get the pay, and the tax box shows the combined federal bill.

Should I tick Step 2 on my W-4 if I have two jobs?

Usually yes. Withholding at each job is set as though that job is your only income. Ticking Step 2 at both jobs, or using the IRS estimator, fixes most of the shortfall.

Do I overpay Social Security with two jobs?

Yes, if your combined wages are over $184,500 in 2026. Each employer withholds 6.2% up to the cap, and the excess is refunded as a credit on your tax return.

What is the weekly paycheck for two jobs?

With $23.50 for 30 hours and $18.00 for 20 hours at different employers the gross weekly pay is $1,065.00.

What is a time pay calculator?

A tool that turns hours and minutes into decimal hours and pay. Enter 7:30 or 7h 30m for 7.5 hours.

Why do I owe tax when I have two jobs?

Because each employer withholds as if you only had that one job, so the second income is taxed at too low a rate. The tax section of the calculator shows the gap.
