How many points do you need to avoid relegation?

By · Published · 7 min read

Ask how many points to avoid relegation and you will get a single number back — usually 40 in a twenty-team top flight. It is a useful number, and it is also the wrong shape of answer. There is no fixed points total that keeps a club up, because the survival line is not a property of the club at all. It is a property of the other clubs in the division, and it is decided by their results, not yours. A team can bank 38 points and go down; a team can bank 33 and stay up comfortably.

What a model can give you instead is the honest version: for any final points total, the probability that it proves to be enough. That curve is far more useful than a threshold, and it explains why the folklore number is set where it is.

How many points to avoid relegation: a line three other clubs draw

Relegation is a ranking outcome, not a scoring outcome. Nothing in the rules says a club falls below a points line. The rules say the bottom three finish bottom three. Whether 36 points puts you 18th or 15th depends entirely on how many rivals finish above you.

That makes the safety line — the points total of the highest-placed relegated club — a random variable in its own right. It has a central value, and it has spread, and both come out of the same place: nineteen other seasons being played simultaneously, each with its own variance.

So survival is a comparison between two uncertain quantities. Your total is uncertain. The line is uncertain. The probability you want is the chance that the first lands above the second, and the spread of that difference is wider than the spread of either piece on its own.

How much luck sits in a single club’s points total

Before comparing distributions it helps to see how wide just one of them is, even when a club’s underlying strength is known exactly.

Take a hypothetical struggling side that, in every one of its 38 matches, has a 25% chance of winning, a 25% chance of drawing and a 50% chance of losing. Its strength never changes and there is no model error anywhere in this example — we are stipulating the probabilities.

Expected points per match are 0.25 × 3 + 0.25 × 1 = 1.0, so the season expectation is 38 points. The variance of a single match’s points is E[X²] − (E[X])² = 2.5 − 1.0 = 1.5, and across 38 independent matches the standard deviation of the season total is √(38 × 1.5) ≈ 7.6 points.

A 95% range therefore runs from roughly 23 to 53 points — a thirty-point spread, generated purely by chance, for a club whose ability we fixed by assumption. Two identical teams in that position can finish a division apart. This is the same variance that makes season simulations produce a range of tables rather than one, and it is why a club’s final total tells you much less about how well it played than the table implies.

Turning points into a survival probability

Now put the line back in. Suppose that, across many simulated seasons of a particular division, the highest relegated club finishes on an average of 35 points with a standard deviation of 3. Those are illustrative figures chosen to make the arithmetic legible, not measurements — but the shape they produce is the shape every real survival curve has.

For a club finishing on a given total, survival is the probability that the line lands below it. With a line centred on 35 and a spread of 3:

Final points Standardised distance from the line Approximate survival probability
32 −1.0 ~16%
35 0.0 ~50%
37 +0.67 ~75%
38 +1.0 ~84%
40 +1.67 ~95%
43 +2.67 ~99.6%

Read the column on the right and the folklore falls into place immediately.

Where the 40-point rule of thumb comes from

Notice that in this illustration the typical requirement is about 35 points. Forty is nowhere near the middle of the distribution — it is out in the tail, at roughly the 95% mark.

That is not an error in the rule of thumb. It is the whole point of it. A rule of thumb is chosen to be the number you can rely on, not the number you usually need. Nobody wants a survival target that works half the time. The quoted figure drifts towards the total that has almost always been sufficient, which sits several points above the total that is normally sufficient — so the rule of thumb is systematically conservative by construction.

This resolves an argument that recurs endlessly: whether the 40-point mark is a myth because clubs routinely stay up on less. Both halves are true and they are not in conflict. Most seasons the line falls well below 40. Forty is the number that is safe nearly every season. A conservative threshold and a lower typical outcome are exactly what a distribution with this shape produces.

Why the number is different in every division

Because the line is produced by the division’s structure, changing the structure moves it. Three things do most of the work.

Matches played. More fixtures means more points available and a higher line in absolute terms. A 46-match second-tier season simply has more points in it than a 38-match Premier League season, so the two thresholds are not comparable as raw numbers.

Teams down, teams up. Survival means avoiding the bottom n. A division relegating four of twenty puts the line at the 17th-placed club rather than the 18th, which raises it. The count of relegation places changes the question being asked.

How spread out the division is. In a league with a wide gulf between strong and weak clubs, the bottom teams are far adrift and the line settles low and predictably. In a tightly packed division the clubs around the line are close in strength, so the ordering down there is decided by small margins and the line’s variance rises — which flattens the survival curve and makes any given total less decisive.

Goal difference adds a final layer of noise. When two clubs finish level on points, a tiebreaker resolves the position, so even a known points total does not fully determine survival at the boundary.

What moves the line while a season is running

Mid-season, a survival probability is a live quantity, and it moves for two distinct reasons that are worth separating.

The first is your own results, which shift your projected total. The second is everyone else’s, which shifts the line — and this is the one that surprises people. A club can win and see its survival probability fall, because rivals won too and the line rose faster than the club’s own total. Nothing has gone wrong when that happens; the model is tracking a relative quantity.

As fixtures run out, both distributions narrow. Early on, variance dominates and probabilities swing hard on single results. By the closing weeks most of the uncertainty has resolved and the curve becomes steep: a few points separate near-certain survival from near-certain relegation. That steepening is the reason late-season swings feel so violent.

Reading a survival number honestly

Three habits make these figures useful rather than decorative.

Treat the threshold as a range. Any site quoting a single “points needed” figure has collapsed a distribution into its tail. Ask which end of it you are being shown.

Distrust precision in season-level forecasts. A relegation probability resolves exactly once per club per season, which means it is nearly impossible to hold to account. A club given a 5% relegation chance that goes down has not falsified anything — 5% events happen. This is why we publish match-level results, where thousands of resolved predictions can actually be scored, on our public track record rather than claiming credit for season calls.

Ask what is underneath. Season probabilities are just match probabilities plus arithmetic. If the match model is well calibrated, the survival curve inherits that; if it is not, no amount of simulation repairs it.

The most familiar version of that number — the 40-point rule — survives precisely because it is conservative enough to be right most years, which is not the same as being a threshold.

The best answer to how many points a club needs is therefore a curve, not a number — and the curve is honest about something a threshold hides: for a large band of plausible totals, survival is genuinely uncertain, and it depends on results the club has no say in.
