FAQ

How is a loan payment calculated?
The monthly payment uses the standard amortizing loan formula from principal, APR, and term. Extra monthly payments are added on top of that base payment.
How do extra payments save interest?
Extra principal shortens the schedule, so fewer months accrue interest. The snapshot table shows how the first 12 payments split between principal and interest.
What types of loans can I estimate?
Any fixed-rate amortizing loan: auto, personal, student, or mortgage. Adjustable rates and fees beyond APR are not modeled.
