What will it cost to keep using it?
Compare two options, then decide whether either fits everyday life. A lower price does not make a product a better choice.
Use written quotes or current checkout figures in US dollars. Include required extras and taxes in the relevant amounts. Enter annual totals for service—not the advertised monthly equivalent. Multiply a monthly fee by 12; enter an annual fee once.
Nothing you enter is sent to us or saved by this tool. Use Clear entries when finished, especially on a shared device. Avoid personal or health information. These calculations do not assess medical suitability or predict future price changes.

These invented amounts explain the calculator. They are not prices for any real product.
| Cost | Example A | Example B |
|---|---|---|
| Upfront | $100 | $200 |
| First-year service | $240 | $180 |
| Renewal service | $300 | $180 |
| Annual upkeep | $20 | $10 |
| First-year total | $360 | $390 |
| Renewal-year total | $320 | $190 |
Example A costs less in year one; Example B costs less in the renewal year. Neither total establishes suitability. A $20 monthly service fee becomes $240 for 12 months; a $240 annual fee is entered once.
Your cost comparison
US dollars. First year = upfront + first-year service + annual upkeep. Renewal year = renewal service + annual upkeep, with no new equipment purchase. Totals use the entered quotes, include only costs entered, and assume unchanged upkeep. Confirm taxes, required extras, renewal rates and cancellation terms with each provider. This is not a provider quotation or a suitability assessment.

Check the fit before choosing
- Does your parent want it, and can they comfortably use the controls?
- Will it work with the exact phone, connection and location?
- Who will handle charging, setup, updates and support?
- What happens during an outage or when nobody sees an alert?
- What are the return deadline, minimum term and cancellation steps?
The renewal calculation excludes another equipment purchase and assumes the same annual upkeep. Add replacement equipment if you expect it. The calculation compares money only; the options may perform different jobs.
