How subscription cost audit works
Subscriptions are hard to total because they arrive in mixed cycles: a weekly plan here, an annual renewal there, everything else monthly. The audit normalizes each one to a common basis — annual cost = amount × payments per year (weekly ×52, biweekly ×26, monthly ×12, quarterly ×4, yearly ×1), then monthly = annual ÷ 12 — so a 95.88 yearly plan reads as 7.99 per month next to a 15.99 monthly one.
Enter each subscription with its price and cycle; the tool returns the per-item monthly and annual cost, each item's share of total spend, the combined monthly and annual totals, and a daily average (annual ÷ 365). The item list is sorted by annual cost for the "biggest leak first" view. Seeing that a 9.99 weekly plan is actually 519.48 a year is the entire point of the exercise.
Everything runs in your browser — the list is never sent anywhere — so the audit is safe to do with real numbers. A good cadence is once a quarter: list, total, and cancel whatever you did not consciously choose to keep. The annual total is usually the number that changes behaviour; the monthly total is the number that hides from it.
