How fast can a 3D printer pay for itself?

It depends on usage. If you regularly buy items that could be printed (phone cases, brackets, organisers), a £300 printer can pay for itself in 3-6 months. Occasional hobbyists might take a year or more.

What costs should I include?

Include filament, electricity, and replacement parts (nozzles, belts). Do not forget your time if comparing against buying finished products commercially.

Is it cheaper to buy or 3D print?

For simple commodity items, buying is usually cheaper. 3D printing excels for custom parts, replacements for discontinued items, and small batch production where tooling costs make traditional manufacturing expensive.

Printer ROI Calculator — Payback Period

Calculate how quickly your printer pays for itself based on usage.

Printer Cost

Up-front price you paid (or will pay) for the printer, including any essential add-ons

Prints per Month

Number of items you print each month that you would otherwise have bought ready-made

Monthly Filament Cost

Total £ you spend on filament each month, across all spools

Monthly Electricity Cost

Total £ you spend on electricity for printing each month (a 200W printer at the Ofgem 26.11p/kWh cap costs roughly £1.55 per 30h of printing)

Avg Purchase Price per Item

What you would pay to buy each item

How We Calculate This

Formula

Monthly savings = (Prints x Purchase price) - Monthly running costs
Months to ROI = Printer cost / Monthly savings
Year savings = Monthly savings x 12 - Printer cost
Cost per print = Monthly costs / Prints per month

This compares the cost of printing items yourself versus buying them ready-made. The more you print, the faster the payback.
