I found $67 in missing night differential on my first paycheck check. One missed diff on a 12-hour night shift and Pro already paid for itself.
I float between three units with different premiums. Being able to switch profiles and compare shifts in the parking lot before I commit - that’s worth more than $8.
As a new grad I had no idea my night differential should be included in the overtime rate. ShiftWorth showed me the math and I finally understood my pay stub.
Free to calculate. One-time upgrade for power features.
For standard 40-hour workweeks, federal overtime review is based on the regular rate, which can include eligible shift differentials. ShiftWorth helps you estimate that review, save the ruleset context you used, and compare it against your paycheck. Employer policies, union agreements, and state rules can still change the final result.
Absolutely. ShiftWorth works 100% offline. No account required, no data leaves your device, no analytics tracking. Your pay information stays on your phone, period.
Because charging nurses monthly for a calculator feels wrong. ShiftWorth runs entirely on your device with no server costs. One fair price, lifetime access.
Yes, especially for hourly taxable pay comparisons across facilities. If a contract includes stipends or non-taxable components, treat ShiftWorth as a partial estimate rather than the full contract calculator.
Tax estimates use your saved filing status, pay frequency, W-4 inputs, and 2026 federal and state tables. They are still estimates for planning purposes, and your actual withholding can vary based on deductions, benefits, and employer payroll settings.
ShiftWorth generates a PDF proof packet with your estimate, likely discrepancy reasons, tax profile, and saved ruleset context. You can also draft a neutral payroll email directly from the app. Use these to start a factual conversation with HR, payroll, or your union rep.
Under FLSA guidelines, shift differentials generally should be included when calculating the regular rate for overtime. That means overtime pay may be higher than just 1.5x your base rate. ShiftWorth estimates this weighted regular rate automatically and shows you the math.
Overtime itself is not taxed at a special rate. But a larger paycheck pushes your withholding into a higher bracket for that pay period, so it looks heavier. ShiftWorth separates the shift value estimate from the withholding estimate so you can see whether a shift is actually bad or just withheld differently.
