The Real Math Behind Slot RTP (And Why It Matters)
November 02, 2026 - iGaming
Ordering 300 copies of a book feels like a modest decision. Then the quote arrives and the arithmetic stops being obvious. The same title that costs a few pounds a copy at 1,000 copies costs noticeably more at 250, delivery is quoted separately, and nobody has mentioned the barcode. A short run is not a long run scaled down: the fixed costs sit on fewer shoulders, and the balance between line items shifts.
The way through is to build the budget from the specification upwards, one line at a time, knowing which costs are fixed, which scale with quantity, and which only turn up once there are boxes in your spare room.
Printers price a specification, not an idea. Before you ask for a single quote, write down the extent (page count), trim size, paper stock for text and cover, binding style, and any finishing such as foiling or spot UV. Then hold that specification still while you compare suppliers.
This matters because quotes are only comparable when the spec matches. Two printers asked for "a 200-page paperback" will quietly assume different paper weights, different cover boards and different delivery terms, and the cheaper quote may simply be the thinner book. Fix the spec in writing, send the same document to everyone, and ask each printer to flag anything they have substituted.
For most indie publishers, manufacturing is 50–70 per cent of the total budget. Within that figure, setup, paper, printing and binding behave very differently.
Digital printing has little or no setup, so it suits runs in the low hundreds and makes reprints easy. Its weakness is that the unit cost falls slowly as quantities rise. Offset printing requires plates and a make-ready, which is expensive once and cheap thereafter, so the unit cost drops steeply. The crossover point where offset becomes cheaper depends on format, extent and colour; for a typical black-and-white novel it tends to sit in the high hundreds or low thousands, and later for full-colour work. Ask your printer where it falls for your book rather than guessing.
Ask for unit costs at several quantities in one request: 100, 250, 500, 750 and 1,000. It costs you one email and shows exactly how much you gain by printing more — and, just as usefully, how little you gain by printing 50 extra. Copies printed beyond the agreed run and then bound, sometimes called run-ons, are often better value than a fresh short run later, so ask what an extra 100 would add.
Paper is a substantial slice of any print quote and its price moves with the market. Ask how long the quoted paper price is held, because a quote valid for thirty days and one valid for ninety are not the same offer.
Small choices have real consequences. Moving from 80gsm to 100gsm text paper makes a thin book feel substantial, but it also increases thickness, which affects postage on every copy you post. On the cover, matt or gloss lamination is routine; foiling, embossing and spot UV each add a separate pass through the press. For binding, perfect binding is the standard paperback method, section sewing lies flatter and lasts longer, and case binding is the hardback option.
One detail worth knowing: offset presses print in signatures, so page counts usually need to be multiples of 16 or 32. Going from 160 to 168 pages may cost as much as going to 176. Ask where the breaks are before you finalise the text.
Delivery is frequently quoted separately, and the terms matter. A pallet left kerbside is cheaper than one delivered with a tail-lift, and if you have no loading bay or forklift you will need the tail-lift. Residential addresses and split deliveries often carry surcharges.
Printing abroad can reduce the manufacturing cost, but add sea or air freight, customs clearance, import duty, VAT on import and agent fees to the comparison. If you are considering it, speak to a freight forwarder and to an accountant before you commit; the tax and duty position is worth getting right from the start.
Then there is storage. Books are heavy, they dislike damp, and a garage floor is a poor home for them. If you would rather not pack parcels yourself, fulfilment services charge a pick-and-pack fee plus postage, and you will still be buying mailers, tape and labels.
This is where short-run budgets most often go wrong. Add these before you decide anything is affordable:
Set aside 10–15 per cent of the total as contingency, and treat it as untouchable. Something will change: a reprint of a corrected page, a heavier paper than expected, a customs charge, a delivery that has to be redirected.
Cash flow deserves as much attention as cost. Many printers ask for a deposit at order and the balance before or on delivery, which means paying for stock months before most of it sells. Build the timeline backwards from your publication date and check that the money going out and the money coming in do not collide.
A budget is sound when you can explain every line to somebody else and the contingency is still sitting there untouched. Judge your costs per copy sold rather than per copy printed — unsold stock is not free, it is simply a cost waiting to be recognised. If you are unsure how to treat stock, VAT or income from book sales, a good accountant is worth more than a clever spreadsheet.
