Work out subscription cancellation saving instantly with clear inputs, formula shown and shareable results.
A 12.99 monthly subscription is 155.88 a year, and invested at 5% instead it compounds to over 2,000 across ten years. Framing the decision that way, rather than as thirteen pounds a month, is what makes subscription creep visible.
Subscription cost
annual = monthly x 12; invested value = monthly x ((1 + r)^n - 1)/r
Each individual charge is small and automatic. There is no repeated decision point, so the cost never gets reassessed against the value.
Audit statements once a year, and prefer annual payments where you must consciously renew rather than monthly auto-renewals.
