What this calculator estimates
Estimate lost income and benefits cost during an unpaid or partly paid FMLA leave. It runs locally in the browser and is intended for planning and comparison.

How the calculation works
Normal pay and benefit costs are compared with paid leave, wage replacement and other support.
Input checklist
The FMLA Income Gap Calculator uses the values shown in its form. Before calculating, check each input independently so an incorrect unit or time period does not carry through to the final result.
- Normal weekly take-home pay ($): verify that this value uses the unit, period, and definition shown by the calculator.
- Leave weeks: verify that this value uses the unit, period, and definition shown by the calculator.
- Percent of pay replaced (%): verify that this value uses the unit, period, and definition shown by the calculator.
- Weekly employee-paid benefits during leave ($): verify that this value uses the unit, period, and definition shown by the calculator.
- Available paid leave or employer support ($): verify that this value uses the unit, period, and definition shown by the calculator.
Practical interpretation
Use the FMLA Income Gap Calculator result as the answer to the specific inputs entered, not as a universal value. The calculation currently described on this page is: Normal pay and benefit costs are compared with paid leave, wage replacement and other support. Change one important input at a time when comparing scenarios so you can see which assumption actually drives the difference.
Checks before relying on the result
The result depends on the values and units entered. Recheck the inputs and compare the estimate with the real-world source or rule that applies to your situation. Recalculate when a key value changes, and keep the original inputs with the result if you need to reproduce or compare the calculation later.
Important limitations
FMLA protects eligible leave but does not itself require paid wages; state and employer programs vary.
