How the calculation works, and its limits
- Known costs = upfront charges + monthly charge × months + annual charge × the number of twelve-month periods rounded up.
- Upfront charges and the first monthly and annual charges are assumed payable at the start. Annual charges are prepaid. A six-month period therefore includes one full annual charge.
- An expressly refundable deposit is shown separately and is not counted as consumed cost. Repayment is not guaranteed; retained or non-refundable amounts belong in charges.
- Starting payments include known upfront charges, the first monthly and annual charge, and the deposit. An exact monthly payment schedule is not calculated.
- Not modelled: price changes, discounts, variable usage, repairs, finance, resale value, tax recalculation, funding or cancellation charges. The selected period does not change a contractual minimum term.
- A lower amount does not establish suitability or equal service. Calling a relative and reaching a continuously staffed monitoring centre, for example, are different services.
The check organises your figures only. It does not review a contract or recommend a provider.
Before agreeing to an offer
- Are the service scope, support and availability genuinely comparable?
- What other upfront, recurring or usage-based charges apply?
- What is the minimum term, how can I cancel, and what charges remain?
- Is the deposit fully refundable, under which conditions, and when?
- Which functions remain available without an extra subscription or during an outage?
