Gender Pay Gap Calculator
Declared unadjustedgenderpaygap(male−female)/male×100, actual matched gross hourly group means, census categories externally observed; negative gap retained, no personal gender inference or adjusted causal discrimination estimate.
Description
The unadjusted gender pay gap compares matched gross hourly group means.
The unadjusted gender pay gap compares matched gross hourly group means.1
It describes an observed difference without isolating the causes of that difference. The calculation and input requirements are explained below.
When to use Gender Pay Gap Calculator
Enter positive male gross hourly mean pay and nonnegative matched female mean pay in the same currency.
How to use Gender Pay Gap Calculator and how it works
- Prepare the measurements or independently established model inputs described below, with matching units and observation scope.
- Enter the required fields and run Gender Pay Gap Calculator.
- Read the result fields using the formula, output units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualMaleGrossHourlyPay | Actual Male Gross Hourly Pay. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
| actualFemaleGrossHourlyPay | Actual Female Gross Hourly Pay. Use the units and matching context stated in the calculation below. | number | Required; nonnegative; finite; other constraints below |
Enter positive male gross hourly mean pay and nonnegative matched female mean pay in the same currency. Return male-minus-female divided by male, times 100. Higher female mean pay yields a negative gap; no covariate adjustment or causal analysis occurs.
gapPercent=100*(maleMean-femaleMean)/maleMean Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Numeric result under the formula and output units explained above. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
