Add recurring app, streaming and software costs. Convert annual bills to monthly averages and estimate multi-year spending and cancellation savings.

How it works

Annual cost = 12 × the sum of monthly groups + annual-billed costs. Divide by 12 for the monthly average and multiply by years for the horizon. Cancellation savings = selected monthly cancellations × 12; annual contracts stay included.

Example: monthly costs of 399 + 299 + 199 and annual costs of 1,200 total THB 11,964 a year, or THB 997 a month. Cancelling THB 199 a month saves THB 2,388 a year.

Use final prices including tax in one currency. Prices stay constant and cancellations take effect before the next cycle. This tool does not cancel services or model penalties and partial refunds.

Frequently asked questions

Where do yearly plans go?

Add them to the annual-billed field; do not repeat them in monthly groups.

Is annual billing cheaper?

Compare twelve monthly payments with the actual annual quote, and consider whether you will use the full year.
