THE OWNERSHIP COST CALCULATOR

Plan beyond the price tag.

Estimate the costs you know, from the first package to the years after it. Blank costs are excluded, not assumed to be free.

Changing currency does not convert amounts. Use a decimal point for cents. Enter 0 for a cost you know is zero.

01 / BEFORE THE FIRST DAY

The complete package price, not just a reservation deposit.

Add charges outside the purchase price. Avoid counting included tax twice.

Required computer, controller, tools, power supply or other one-time equipment.

02 / KEEPING IT RUNNING

Subscriptions, connectivity or service charges paid each month.

Energy, consumables and an allowance for routine replacements or repairs each year.

THE ARITHMETIC, OPEN TO INSPECTION

Buy once.
Budget for the years.

Upfront = purchase price + delivery/tax + setup.

Yearly running costs = monthly services × 12 + annual upkeep.

Total = upfront + yearly running costs × ownership years.

Upkeep is an allowance, not a quoted repair charge. Include required costs you can establish, and keep unknown costs visible. Check the complete edition and contract before committing to a purchase.
