Overtime vs Second Job Calculator

Compare the net income from working overtime at your current job versus taking on a second job. Factor in tax rates, commute costs, and time to find the better option.

About this calculator

Overtime Weekly Net multiplies your Current Hourly Rate by the Overtime Multiplier and by Overtime Hours Per Week to get gross overtime pay, then applies your Tax Rate to convert it to take-home pay. Second Job Weekly Net follows the same gross-to-net pattern, but first subtracts an estimated weekly commute expense derived from your Daily Commute Cost and the number of days implied by your weekly hours (capped at 5 working days), before taxes are applied. Current Hourly Rate, the Overtime Multiplier, and Overtime Hours Per Week each move Overtime Weekly Net by roughly the same proportion for an equivalent percentage change, since all three multiply together directly -- no single one of them clearly outweighs the others.

Better Option simply compares the two Monthly Net figures and reports whichever is larger, while Annual Difference multiplies that monthly gap by 12 to show the yearly stakes of choosing one option over the other. This model assumes your Overtime Multiplier and hours reflect what your employer will actually authorize, and that the second job's advertised hourly rate and hours are consistently available -- it does not account for irregular overtime approval, second-job scheduling conflicts, or the non-financial cost of added fatigue or reduced time off from working substantially more hours.

How to Use This Calculator
  1. Enter your current hourly rate and the overtime rate (typically 1.5x your base rate).
  2. Set the number of overtime hours per week you could work.
  3. Enter the second job's hourly rate, hours per week, and estimated weekly commute cost.
  4. Input your combined marginal tax rate so both options are compared on an after-tax basis.
  5. Review Overtime vs Second Job weekly and monthly net to determine which earns more for your time.

What each input means

Current Hourly Rate
Your regular hourly pay at your primary job.
Overtime Multiplier
Overtime pay multiplier (1.5x is standard time-and-a-half).
Overtime Hours/Week
Number of overtime hours available each week.
Second Job Hourly Rate
Hourly pay at the second job.
Second Job Hours/Week
Hours per week at the second job.
Second Job Daily Commute Cost
Daily transportation cost to the second job.
Tax Rate
Combined federal and state marginal tax rate.

Frequently Asked Questions

Why does raising the Overtime Multiplier have about the same effect as raising my Hourly Rate?

Overtime Weekly Net is the direct product of Current Hourly Rate, the Overtime Multiplier, and Overtime Hours Per Week -- three factors multiplied together rather than added. Nudging any single one of those three factors up or down by some share moves the final result by roughly that same share, which is why no single factor clearly dominates the others here. A 10% raise in your base rate and a 10% bump in the overtime multiplier move your overtime pay by nearly the same amount.

How does the calculator estimate weekly commute cost for the second job without asking how many days I work?

It estimates working days from your Second Job Hours Per Week, dividing by 4 (assuming roughly 4-hour shifts) and capping the result at 5 days, then multiplies that estimated day count by your Daily Commute Cost. This is an approximation rather than an exact schedule -- if your actual shift length or work pattern differs meaningfully from that assumption, your real commute cost may be higher or lower than the estimate shown.

Does the Annual Difference account for the extra fatigue or lost personal time from working more hours?

No -- Annual Difference is purely a financial comparison, calculated by multiplying the monthly gap between the two options by 12. It says nothing about the non-financial cost of overtime or a second job, such as reduced rest, family time, or burnout risk, which are real factors many people weigh alongside the dollar figures before committing to either option.

Why might overtime pay more per hour than a second job even at a lower listed rate?

Overtime pay is boosted by the Overtime Multiplier -- commonly 1.5x under standard time-and-a-half rules -- applied directly to your existing hourly rate, while a second job's hourly rate stands alone and is further reduced by commute costs before it's even taxed. A second job would need a meaningfully higher stated hourly rate than your primary job's overtime rate to come out ahead once the multiplier and commute costs are both factored in.
