How to break 80, 90 or 100

Updated . Sources are listed at the foot of the page.

To break a score, work out how many strokes over par you are allowed, then decide in advance where you will spend them. On a par-72 course, breaking 100 allows 27 over par, breaking 90 allows 17 and breaking 80 allows 7. Most rounds above a target are lost to a handful of expensive holes, not to a general lack of skill. The worksheet below shows where yours go.

We do not issue handicaps, we are not affiliated with any club or governing body, and nothing here is an official handicap. This page is arithmetic and habit. It is not a swing lesson and promises no result.

The arithmetic

Every target is a strokes budget. Take the target, subtract one (breaking 90 means 89 or lower) and subtract the course par.

TargetHighest scoreStrokes over par allowed (par 72)Average per hole
Break 10099271.5 over
Break 908917just under 1 over
Break 80797well under 1 over

If the course you play has a par other than 72, subtract your own par. The method does not change.

Two facts make this useful. First, eighteen bogeys is 90 on a par 72, so a golfer who bogeys everything is one stroke from breaking 90 and needs only a single par. Second, a double bogey costs two strokes against par and a bogey one. One doubled hole spends the budget of two ordinary bogeys.

Step 1: set the target and the budget

Write down your target, the course par, and the difference. This is your budget: the number of strokes over par you can afford. Use a target one step beyond your recent scores, not three steps beyond. A golfer who usually shoots 96 does better aiming at 89 than at 79.

Step 2: audit your last five rounds

Take your last five scorecards and count, for each round, the holes that cost you more than a bogey, the penalty strokes, and the three-putts. Average them. These are the places your budget is already going.

LeakStrokes lost per round (average of five)
Holes worse than bogey (count the strokes beyond bogey)
Penalty strokes (water, out of bounds, lost ball)
Three-putts and worse (count one stroke for each)
Shots lost from the tee to trouble, then recovery
Total

An honest total tells you whether the target is a plan or a hope. If your average already runs a few strokes over your budget, the leaks above are where those strokes are.

Step 3: spend the budget on purpose

Divide the budget into three pots before you play. A worked example for breaking 90 on a par 72, with a budget of 17:

PotAllowanceWhat it covers
Ordinary bogeys12Twelve holes you expect to play in one over, with no drama
Doubles2 holes (4 strokes)Two holes may go wrong, and that is already planned
Reserve1One stroke you can lose without changing the plan

Twelve bogeys, two doubles and a reserve account for 17. The remaining holes are then played at par. You do not need heroic golf. You need to avoid a third double, a lost ball you could have avoided, and a three-putt from a careless first putt.

For breaking 100 the budget is 27, which is larger than it sounds: eighteen bogeys use 18 and leave nine strokes for trouble. A bogey on a par 4 is a green reached in three and two putts, which is a modest plan. The worksheet only asks you to count those holes honestly.

For breaking 80 the budget is 7. Seven bogeys and eleven pars do it, and so does five bogeys, one double and twelve pars. There is very little room, and the first leak to close is the penalty stroke. The audit in Step 2 matters more here than anywhere else.

Step 4: three rules the budget gives you

  1. Play for the next bogey, not the miracle. When a hole goes wrong, the question is how to make the next stroke the last expensive one. A double bogey played as a double stays a double. Chasing a par makes it a triple.
  2. Penalty strokes are the most avoidable. Under Rule 17.1d every relief option for a ball in a penalty area costs one stroke (you may also play it as it lies, free, under Rule 17.1b). Under Rule 18.2b a lost ball or one out of bounds costs a stroke and the distance. Playing a provisional ball when your ball may be lost outside a penalty area or be out of bounds (Rule 18.3) saves the walk back and the time. Before the round, mark on your card the holes where the trouble is, and choose a club that avoids it.
  3. Count the putts you throw away. A three-putt gives back what a good approach earned. Putt to a spot two feet past the hole at first, then finish. Practise the 3 to 6 foot putt more than the 30-foot one.

Step 5: keep score honestly

A budget only works with a true score. Rule 3.3b puts the responsibility for each hole's score on the player: check every hole before you certify (sign) the card. Rule 1.3b makes you responsible for applying the Rules and your own penalties. If you are unsure of the right procedure in stroke play, you may finish the hole with two balls (Rule 20.1c(3)), and either way raise the doubt with the organisers before you return your card: under Rule 3.3b(3) a doubt you kept to yourself can turn a missed penalty into disqualification.

A filled-in line, for the round itself

Before the round, on the back of the card, write one line per budget pot. During the round, tick it off.

  • Budget: ____ strokes over par.
  • Bogeys expected: ____. Doubles allowed: ____. Reserve: ____.
  • Holes where I play safe from the tee: ____, ____, ____.
  • Holes where a bogey is a good result: ____, ____.

After the round compare. If you broke the budget on a hole where you took a risk, move that hole to your safe list next time. If you finished under budget, set the next target.

Evidence that recording helps

One data study of 257 club golfers from 2024, published by Golf Insider UK, tracked changes in handicap over the previous 12 months. The average golfer in the sample played about 1.68 rounds a week and practised about three hours a week. The study found that golfers who kept regular playing statistics improved by an average of 3.38 shots, against 1.38 for those who did not. The study is an observational sample, the page is inconsistent about some of its other figures, and we quote only the figures it states consistently. It supports keeping a record. It does not prove that recording causes improvement.

How the Candidacy uses this

Elected Golf is a club entered by a 28-day card. It is not open yet: nothing is charged and no card is asked for. The Candidacy's 28-day golf practice plan includes a Baseline Card on which you record your own numbers and a Game Plan worksheet that builds this budget hole by hole. You can use both without applying. We are not affiliated with any club and cannot secure admission.

What this guide is not

  • We are not affiliated with any club and cannot secure admission.
  • We issue no handicap. Your numbers here are an unofficial Playing Record.
  • Fees and rules change; each figure here carries the date it was read and a link to where it was published.
