Full Perms vs Conditional Bankers: A Beginner’s Walkthrough

If you’ve ever picked up a coupon, nodded along to the phrase “full perm” or “banker selection”, and quietly had no idea what either meant in practice, you’re in good company. These two approaches sit at opposite ends of how pools players turn a shortlist of fixtures into an actual entry, and understanding the mechanics properly is the difference between entering with intent and just hoping for the best.

Step One: Understand What a “Line” Actually Is

A single line on a pools coupon is one specific combination of selections — essentially one bet. If you pick eight matches you think will be score draws and enter them as a single line, you need all eight to come in for that line to pay out at its full value. Most players quickly realise that backing eight picks to all land exactly is a tall order, which is exactly the problem that perms and bankers are built to solve: spreading risk across multiple lines rather than betting everything on one.

Step Two: How a Full Perm Works

A full permutation takes a pool of selections larger than the number you need and generates every possible combination of that size. Say you shortlist ten matches you’re reasonably confident about, but you only need eight correct to win. A full perm of “8 from 10” generates a line for every combination of eight matches drawn from your ten — mathematically, that’s a combinations calculation, written C(10,8).

Working that out: C(10,8) = 45 lines. That means your shortlist of ten matches becomes 45 separate lines, and crucially, you don’t need all ten to come in — you only need eight of your ten selections to be correct, because at least one of those 45 combinations will contain exactly those eight winners.

What That Costs

At an illustrative stake of 10p per line, 45 lines costs £4.50 for that section of the coupon. At 5p per line it’s £2.25, and at 2p per line it’s 90p. These are example stake levels only — actual unit costs depend on the specific coupon and operator — but the arithmetic itself (lines multiplied by stake) always works the same way.

Step Three: How a Conditional Banker Works

A banker is a selection you’re treating as close to certain and fixing into every line, rather than letting it vary across combinations. If you have one match you’re very confident will be a score draw, you can “bank” it — meaning it appears in every line you enter — and then build your perm from a smaller pool of remaining matches.

Using the same overall budget as above: instead of a straight 8-from-10 perm, you bank one selection and build a 7-from-9 perm from your remaining nine matches, needing seven of those nine correct alongside your banker. That’s C(9,7) = 36 lines rather than 45 — a smaller, cheaper perm, because the banker has done some of the work of narrowing things down.

Why This Matters for Risk

The trade-off is obvious once you see it laid out: a banker reduces the size and cost of your perm, but it also means your entire entry now depends on that one fixed selection coming in. Get the banker wrong, and every single line in your entry is affected, regardless of how the rest of the matches go. A full perm with no bankers spreads that risk more evenly, at the cost of needing more lines — and more outlay — to cover the same number of underlying selections.

Step Four: Comparing the Two Directly

Each extra banker you add shrinks the perm and the outlay, but also concentrates more of your result on fewer fixed judgements. There’s no universally “correct” number of bankers — it genuinely depends on how confident you are in any individual selection, and how much of your weekly outlay you’re comfortable committing to that confidence.

Step Five: A Practical Way to Decide

1. List your shortlist of matches and rate your confidence in each honestly, not optimistically.
2. Only bank a selection if you’d still be comfortable with the outcome if that one match let you down and nothing else did.
3. Check the cost of the resulting perm before committing, using the lines-times-stake arithmetic above, so there are no surprises once the coupon is submitted.
4. If the cost of a full perm across your whole shortlist feels too high, trim the shortlist rather than banking selections you’re not genuinely sure about.

Common First-Timer Mistakes Worth Avoiding

A few errors crop up repeatedly among players new to perms and bankers, and they’re easy to sidestep once you know to look for them.

• Banking out of impatience, not conviction. It’s tempting to bank a selection simply to shrink the cost of a perm, rather than because you’re genuinely confident. That inverts the whole purpose of a banker — it should reflect belief, not budget management.
• Forgetting that perm size grows quickly. Moving from an 8-from-10 perm to a 9-from-12 perm doesn’t scale gently — the line count jumps from 45 to 220, more than quadrupling the cost at the same stake. Always recalculate rather than assuming a small change in selections means a small change in price.
• Mixing confidence levels within one perm. Throwing a genuinely uncertain pick into the same perm pool as several strong ones dilutes the value of the whole entry, since every line is only as good as its weakest selection.

Neither method guarantees a return, and no amount of clever permutation structuring changes the underlying uncertainty of football results — that’s the nature of the game, not a flaw in the system. Treat perms and bankers as tools for managing how your stake is distributed, not as a way to manufacture certainty where none exists. Keep weekly outlay to an amount you’ve decided in advance and are comfortable losing, remember this is entertainment rather than income, and stay the right side of 18 before entering anything at all.
