Audits recurring subscriptions (streaming, apps, gym, cloud storage, news) from a simple CSV: true monthly and yearly cost in one currency, your share of family plans, renewals and trial conversions in the next 30 days, unused services, overlapping services in one category, price increases, and annual plans that would save money. Ends with a cancel/keep/downgrade action list. Includes a stdlib Python auditor with --self-test.
Builds fixed-rate loan and mortgage amortization schedules, shows how much of each payment goes to interest, and compares payoff strategies such as extra monthly payments, one-off lump sums, a higher fixed payment, or a shorter term, with interest saved, months saved, payoff date, and an APR estimate when fees apply. Use when a user asks "how much interest will I pay?", "should I overpay my mortgage?", "what if I pay 200 more a month?", or wants a payoff plan for a car, student, or home loan.
