Machine ROI & payback calculator
Before buying a printer, press, embroidery head, or laser: estimate how many months the machine takes to pay for itself and what it returns over your chosen horizon, from extra profit and running costs.

Payback and ROI
Net monthly gain = extra monthly profit − extra running costs − finance payment. Payback = upfront investment ÷ net monthly gain. A £12,000 machine generating £750 net per month pays back in 16 months.
The horizon view answers the follow-on question: over 36 months that machine nets £27,000 against £12,000 invested — a 125% return. If the payback period is longer than the horizon you believe in (or the warranty), that's the red flag.
Estimating "extra monthly profit" honestly
The number to use is marginal profit the machine adds: jobs you currently turn away, outsourcing brought in-house, or hours freed for billable work. Cost those jobs with the job profit calculator first — revenue projections without a cost model are how machines end up as expensive furniture.
Assumptions
Extra profit arrives evenly from month one.
The machine's resale value at the end of the horizon is ignored.
Limitations
- An estimate to structure the decision — not financial advice, and no substitute for a cash-flow forecast.
- Doesn't model tax treatment (capital allowances, VAT reclaim) — these can materially change the real cost; ask your accountant.
- Ignores the time value of money; over horizons beyond ~3 years that flattery grows.
Common questions
Should I use revenue or profit for the monthly gain?
Profit. A machine that adds £3,000 of monthly revenue at a 30% margin adds £900 of profit — using revenue would flatter the payback by 3×.
What's a good payback period for print equipment?
It depends on the machine's realistic working life and how certain the demand is. Many shops look for payback well inside the warranty period, and treat anything beyond 2–3 years on uncertain demand as speculative.

Break-even calculator
Find how many jobs or units you need to sell each month to cover your fixed costs, and how many more to hit a profit target — using contribution margin, the standard break-even method.

DTF cost-per-print calculator
Estimate what each DTF transfer really costs from film, ink, and adhesive powder consumption — with print layout, labour, and waste factored in — so gang sheet and per-print pricing stops being guesswork.
