Financial decision guide and interactive simulator

Contract commitment calculator

What is the full cost of signing this contract?

What this calculation is designed to show

Monthly pricing can hide initiation charges, annual increases, bundled device costs and cancellation fees. The relevant comparison is the total committed cost against realistic month-to-month or cash alternatives.

How to test the decision

Calculate the cost for the period you are likely to keep the service, not only the advertised term. Test early cancellation and a price increase before deciding that the lower monthly offer is cheaper.

Using the result responsibly

Change one important assumption at a time and compare a cautious case with the expected case. The interactive calculator below updates from the values you enter. Its output is an educational estimate, not financial, tax, legal or investment advice.
