Frequently Asked Questions

Q: Why does my remaining balance differ slightly from my bank statement?
A: Minor differences stem from daily interest compounding variations, exact rounding practices, or non-standard fee inclusions by specific financial institutions.

Q: How does early principal prepayment affect this balance?
A: Making extra principal payments reduces the active principal base, causing subsequent calculations to yield lower remaining balances faster over time.
