The 9-From-14 Perm: Working Out 2,002 Lines and Real Cost
Perms confuse plenty of experienced coupon players, not because the idea is hard but because the arithmetic behind it is rarely shown in full. A “9 from 14” entry means picking 14 matches you fancy for the draw column and asking the pools operator to cover every possible combination of 9 selections from within that group of 14. This piece walks through exactly how that number is calculated, what it costs at different stake levels, and why fractional penny stakes matter more than players often realise.
The combinatorial formula
The number of unique 9-match combinations you can draw from a pool of 14 matches is given by the binomial coefficient, written C(14,9), which equals 14! divided by (9! × 5!). Working through the formula by hand:
- 14! ÷ (9! × 5!) simplifies to (14 × 13 × 12 × 11 × 10) ÷ (5 × 4 × 3 × 2 × 1)
- Numerator: 14 × 13 × 12 × 11 × 10 = 240,240
- Denominator: 5 × 4 × 3 × 2 × 1 = 120
- 240,240 ÷ 120 = 2,002
So a 9-from-14 perm generates exactly 2,002 separate lines. Each line is a unique combination of 9 of your 14 chosen matches, and every single one of those 2,002 combinations is staked and settled independently. This is why perms escalate in cost so quickly as the pool of matches grows even slightly — moving from 13 to 14 matches in your base selection takes the combination count from 715 up to 2,002, nearly tripling it, while moving from 14 to 15 would push it to 5,005.
Turning lines into real money
Pools stakes are typically quoted per line, and many operators allow fractional penny stakes — for example 2p, 5p, or 10p per line — specifically so that perms with thousands of lines remain affordable for ordinary players. The maths is simple multiplication once you know the line count:
| Stake per line | Lines | Total outlay (illustrative) |
|---|---|---|
| 2p | 2,002 | £40.04 |
| 5p | 2,002 | £100.10 |
| 10p | 2,002 | £200.20 |
| 20p | 2,002 | £400.40 |
These figures are illustrative only — always check the live stake schedule and any per-coupon minimums before entering a perm, since operators vary and promotions change over time. The point to take away is the shape of the curve: doubling your stake per line simply doubles the total outlay, but widening your match pool from 14 to 15 matches multiplies your line count by roughly 2.5, which is a far bigger jump than most players expect when they casually add “just one more game” to a perm.
Why points accumulate the way they do
Because every one of the 2,002 lines is scored on its own merits, your coupon can register several different point totals simultaneously depending on how many of your 14 matches actually finished as score draws. If, say, 6 of your 14 chosen matches come in as score draws, every line that happens to contain all of those 6 within its 9 selections will score highly, while lines built from a different mix will score lower. A perm does not need every match to land — it is specifically designed to extract value from a cluster of correct picks spread unevenly across your pool, provided enough of your 14 matches come good.
A smaller worked comparison
To see the scaling effect clearly, it helps to compare a few nearby perm sizes side by side using the same formula:
- 8 from 14: C(14,8) = 3,003 lines
- 9 from 14: C(14,9) = 2,002 lines
- 10 from 14: C(14,10) = 1,001 lines
Notice that 8-from-14 actually produces more lines than 9-from-14, not fewer — a point that catches out players who assume “fewer matches picked per line” always means “cheaper perm”. The relationship is symmetrical around the midpoint of the pool size, which is a quirk of the binomial coefficient worth remembering before you commit to a particular block size on the strength of a gut feeling about cost.
How perms interact with partial hits
One of the more reassuring features of a perm, once you understand the mechanics, is how gracefully it handles a partial hit rather than an all-or-nothing outcome. Imagine your 9-from-14 perm is built around 14 matches, and after the weekend’s results, exactly 8 of those 14 came in as score draws (the remaining 6 did not). Rather than the whole perm failing because you missed one correct score draw to make it 9, a meaningful number of your 2,002 lines will still register a high points total, specifically every line that happened to combine 8 or 9 of your correct matches with the right proportion of your incorrect ones falling outside that particular 9-match combination.
This is the structural appeal of perms over straight lines: a straight 9-match line either hits all 9 or it does not, with nothing in between, whereas a perm spreads that same risk across every possible 9-match subset of your wider pool, meaning a strong-but-not-perfect week on your overall selections still produces a cluster of high-scoring lines rather than a single pass-or-fail outcome.
Practical takeaways for coupon planning
Three habits make perms more manageable in practice. First, always calculate the exact line count before deciding on a stake, rather than estimating — the jump between adjacent pool sizes is rarely intuitive. Second, treat the 14 matches going into the perm with real selection discipline; a perm multiplies your stake across many combinations, so a careless 14th selection added “for luck” inflates cost without necessarily improving your coverage of the week’s genuine score-draw contenders. Third, keep a simple log of perm size, stake per line, total outlay, and points returned each week, so you can see over a season whether a particular perm size suits your bankroll and selection style.
Perms are a legitimate way to spread risk across a wider net of matches than a straight line allows, but the cost scales mathematically, not intuitively. Treating the football pools, in any format, as entertainment rather than income is the most important habit of all — set a limit you are happy to lose before you start, and stop there regardless of how the lines are shaping up. Players must be 18 or over, and anyone finding it hard to stick to their own limits should take a break and seek support.
