How the estimate is built

The model subtracts applied payments, begins charges after the contractual grace period, and calculates either simple daily interest or monthly-compounded interest through the selected date before adding a fixed fee.

Important limitation

This is not a legal demand or an accounting posting. Contract terms, consumer-protection rules, court-awarded interest, taxes, payment allocation, waivers, and jurisdiction-specific limits may change or prohibit charges.
