How do bi-weekly repayments save money?

There are 52 weeks in a year, which means 26 bi-weekly payments (the equivalent of 13 monthly payments instead of 12). That extra month's payment each year goes directly toward reducing your principal balance, significantly reducing compounding interest over time.

Can extra repayments be made without penalty?

Most consumer and auto loans have no prepayment penalties, but check your contract terms. For fixed-rate mortgages, some lenders place annual limits on penalty-free early repayments.

What is the difference between principal and interest?

Principal is the actual money you borrowed. Interest is the lender's fee for borrowing that money. In the early stages of a loan, a larger share of each payment covers interest; over time, more goes toward paying down the principal.

💡 See it in action — a real example

A $30,000 personal loan at 7.5% interest over 5 years (60 months): Monthly repayment = $601.14. Total repaid = $36,068.32, with total interest of $6,068.32. Adding an extra $50/month pays the loan off 6 months early and saves $486 in interest.
