Golf Handicap Calculator
Estimate a WHS Handicap Index from 3 to 20 eligible 18-hole rounds, or convert an existing index into Course and Playing Handicaps.
Formula
WHS Score Differential = 113/Slope x (adjusted gross score - Course Rating - PCC). The official fewer-than-20 table selects the lowest differentials and applies its initial adjustment. Course Handicap = Index x Slope/113 + Rating - par; Playing Handicap applies the allowance to the unrounded value.
About the Golf Handicap Calculator
Estimate a WHS Handicap Index from 3 to 20 eligible 18-hole rounds, or convert an existing index into Course and Playing Handicaps. Lifestyle calculators organize the entered scores, schedules, performance values, or personal preferences using the named rule.
How the Golf Handicap Calculator Works
WHS Score Differential = 113/Slope x (adjusted gross score - Course Rating - PCC). The official fewer-than-20 table selects the lowest differentials and applies its initial adjustment. Course Handicap = Index x Slope/113 + Rating - par; Playing Handicap applies the allowance to the unrounded value.
The calculation runs in your browser. Submitted values are validated for the required numeric range, data shape, units, and method-specific restrictions before a result is shown.

How to Use the Calculator
- Confirm that the calculator title and method match the quantity, test, conversion, or planning question you need to solve.
- Enter values with compatible units and the requested sample, group, matrix, count, date, or option format.
- Select Example Data to inspect a valid input layout, or enter your own values and select Calculate.
- Review the result table, formula, worked substitutions, warnings, and interpretation rather than using only the headline number.
- Use Copy Result or Download CSV when you need a reusable record of the displayed calculation.
Understanding the Result
Results are estimates or planning aids and should be interpreted with the rules and limitations shown for the individual calculator.
Keep the entered values, units, selected options, and any warning shown beside the result. For a hypothesis test, report the statistic, degrees of freedom where applicable, p-value, alpha level, effect size, and decision. For an estimate or conversion, report the formula convention and final unit.
Accuracy and Limitations
The calculator keeps full browser precision during calculation and rounds only for display. Accuracy still depends on correct inputs and on whether the displayed model represents the real problem. Educational calculators cannot replace required professional review, current official rules, field measurements, laboratory methods, or specialist statistical software where those are necessary.
