Frequently Asked Questions
What is the difference between simple and compound interest?
Simple interest is calculated solely on the initial principal. Compound interest is calculated on the principal plus any accumulated interest, causing your balance to grow exponentially.
How are monthly loan payments calculated?
We use standard amortization formulas (e.g. fixed monthly payment formula) to resolve exact interest distributions and principal payments.
