Golf Betting Game Calculator
Score Stableford, Modified Stableford, skins and Nassau for a foursome, with proper carryover handling and handicap strokes applied where they fall.
Scoring follows the published rules and is unit-tested: standard Stableford (par 2, birdie 3, eagle 4, and never below zero), the tour-style modified table with its negative bogey values, skins with proper carryover, and Nassau's three separate bets. Match status uses correct notation — "3 & 2" means three up with two to play, and a match decided on the 18th is simply "1 up".
Under Stableford a triple bogey and a twelve are the same score
Standard Stableford pays 2 for a par, 1 for a bogey and nothing at all beyond that. On a par 4 every score from 6 upward collapses to the same zero — 7 distinct scores, one result. Past double bogey the marginal cost of another stroke is exactly zero. That is not a rounding convenience, it is the reason the format exists: stroke play punishes a disaster in proportion to how bad it gets, and Stableford stops counting.
| Score on a par 4 | To par | Standard | Modified |
|---|---|---|---|
| 2 | -2 | 4 | 5 |
| 3 | -1 | 3 | 2 |
| 4 | 0 | 2 | 0 |
| 5 | +1 | 1 | -1 |
| 6 | +2 | 0 | -3 |
| 7 | +3 | 0 | -3 |
| 8 | +4 | 0 | -3 |
| 12 | +8 | 0 | -3 |
For a bogey golfer that floor is not an edge case. Working from a typical spread of hole scores, 25.5% of holes score nothing and 7.5% are strictly worse than a double bogey — about 1.3 holes in a round of 18 where the extra strokes are free. The floor moves with par rather than sitting at a fixed number, so it works the same way on a par 3 and a par 5.
Which means Stableford and stroke play name a different winner once every 15 rounds
Simulating 200,000 pairs of rounds from that same distribution, the two formats disagree about who won in 13,081 of them — 6.54%. Take a 10 on a par 4 and par the other seventeen and you are one stroke worse than a player who bogeyed five holes, and three points better. Picking the format is not a scoring convenience; it changes who buys the drinks.
| Scoring | Mean per hole | Standard deviation |
|---|---|---|
| Strokes to par | -0.910 | 1.064 |
| Stableford points | -0.820 | 0.899 |
| Modified Stableford | -1.000 | 1.428 |
And Modified Stableford is not the same game with different numbers
It is a deliberately noisier one. Measured relative to par — which is the only fair comparison, since standard pays 2 for a par and modified pays 0 — both tails are stretched, not just the upside.
| Result | Standard, relative to par | Modified, relative to par |
|---|---|---|
| Eagle | +2 | +5 |
| Birdie | +1 | +2 |
| Par | 0 | 0 |
| Bogey | -1 | -1 |
| Double or worse | -2 | -3 |
An eagle is worth 2 birdies under standard scoring and 2.5 under modified. A double costs 2 bogeys under standard and 3 under modified. Run the same golf through both and the spread of points per hole is 1.59 times wider under modified. That is the point of the format on tour: it pays for going at pins and it makes the leaderboard move. What it does not do is remove the floor — modified truncates at double bogey too, so it buys volatility on the upside without ever charging for the downside.

Frequently asked questions
How does Stableford scoring work?
Points by result against par: typically 2 for a par, 3 for a birdie, 4 for an eagle, 1 for a bogey, and none for worse. It rewards aggressive play and lets you pick up on a bad hole without wrecking the round, which is why it is popular for club competitions and slow-play reasons.
What is Modified Stableford?
A more aggressive variant with a wider spread — larger rewards for eagles and birdies and an actual penalty for bogeys and worse. It is used on tour occasionally and produces genuinely different strategy, since laying up costs points in a way it does not in standard Stableford.
How do skins work with carryover?
Each hole is worth a skin, and it is only won outright — if two or more players tie the low score, the skin carries to the next hole. Carryovers accumulate, which is why a single hole late in a round can be worth a great deal and why the format stays interesting.
What is a Nassau?
Three separate bets in one: front nine, back nine and overall match. It keeps a round meaningful for someone who loses the front badly, since two bets remain live. Presses — additional bets started when someone falls behind — are a common addition and worth agreeing in advance.
Where do handicap strokes fall?
On the holes ranked by the stroke index on the scorecard, hardest first. A player receiving six strokes gets them on the six holes indexed 1 through 6. Getting this wrong is the most common source of scoring disputes in casual games.
What should be agreed before starting?
The stakes, whether presses are allowed and who can call them, how ties are settled, and whether handicaps apply and at what percentage. Almost every argument about a golf bet traces to something nobody clarified on the first tee.
