A practical planning tool
What will ownership cost?
Put the device price beside its setup, subscription and consumable costs. Use your own quotes; these example values are not a product offer.
How it is calculated
Device + one-off setup + years × (12 × monthly subscription + annual consumables).
The example is £200 + £30 + 3 × (£60 + £40) = £530 over three years. Use costs in one currency on a consistent tax basis. Changing the currency label does not convert values.
Fixed example: what £5 a month adds
This chart does not change when you edit the calculator.
| Years | With £5/month fee | Without fee |
|---|---|---|
| 1 | £330 | £270 |
| 3 | £530 | £350 |
| 5 | £730 | £430 |
What this leaves out
Financing, inflation, unexpected repairs, resale value and energy costs unless you add them to annual costs. Enter only incremental consumables if your existing routine already incurs some of them. Do not count the same cost twice.
A monthly equivalent is not a payment schedule: a multi-year service may be billed upfront. This tool assumes service for the selected period and does not estimate unused prepaid time or cancellation refunds.
Lower cost is not a verdict on suitability, quality or safety.
