Personal Loan Calculator with Amortization

Most mainstream lenders require a minimum credit score of 580-640 for approval. Borrowers with scores above 720 typically qualify for the best rates, while those in the 640-720 range may be approved but at higher interest rates. Some online lenders serve borrowers with scores as low as 550, but rates can exceed 30% APR at that level.

An amortization schedule is a table showing every monthly payment broken down into principal and interest, along with the remaining loan balance after each payment. Early payments are mostly interest, while later payments are mostly principal. The schedule helps you see exactly how your balance decreases over time and how much of each payment actually reduces your debt.

A longer term lowers the monthly payment but significantly increases total interest paid. A $15,000 personal loan at 10% costs about $319/month over 5 years for a total of $19,122. At 7 years it costs $241/month but a total of $20,263 -- $1,141 more in interest. The extra two years of payments costs more than the monthly savings.

Yes, extra principal payments reduce your balance faster, which means interest accrues on a smaller amount. On a 5-year, $15,000 loan at 10%, adding just $50 per month in extra principal pays the loan off 10 months earlier and saves about $500 in interest. The exact savings depend on your rate, balance, and when in the loan term you start making extra payments.
