Golf Slope Rating Calculator
Work out how slope rating changes strokes received across tee options.
About Golf Slope Rating Calculator
Because the slope adjustment is multiplicative, higher handicappers gain more strokes when moving to a harder tee than low handicappers do. That is the intended effect of the system. Ignoring slope when playing from different tees produces systematically unfair matches, which is why the World Handicap System made the adjustment mandatory.
Formula
Golf Slope Rating
Strokes received scale with slope ÷ 113, plus any course rating difference
- slope 113
- The standard reference for a course of average difficulty
- stroke difference
- Extra strokes received when moving to a harder tee
Worked example
With the default values below, Golf Slope Rating Calculator returns Difference in Strokes Received of 6.00. Change any input above and every figure here is recalculated in your browser.
Inputs used
- Handicap indexaccepts -10–54
- 18
- Slope rating of the first teeaccepts 55–155
- 113
- Slope rating of the second teeaccepts 55–155
- 138
- Course rating difference between teesaccepts -10–10

Results
- Difference in Strokes Received
- 6.00 strokes
- Course Handicap at the First Tee
- 18
- Course Handicap at the Second Tee
- 24
- Slope Ratio Between Tees
- 1.2212
- Interpretation
- The second tee is harder, so more strokes are received there

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- These figures are estimates based on population-average formulas and are intended for training and recreational planning only. They are not medical advice. Consult a qualified health professional before starting or changing an exercise programme, particularly if you have an existing medical condition.

Frequently Asked Questions
How is Golf Slope Rating calculated?
Strokes received scale with slope ÷ 113, plus any course rating difference Because the slope adjustment is multiplicative, higher handicappers gain more strokes when moving to a harder tee than low handicappers do. That is the intended effect of the system.
Why does Golf Slope Rating matter?
Ignoring slope when playing from different tees produces systematically unfair matches, which is why the World Handicap System made the adjustment mandatory.
What values do I need to enter?
This calculator takes 4 inputs: Handicap index, Slope rating of the first tee, Slope rating of the second tee, Course rating difference between tees. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
