How to use this calculator
Enter the loan amount, rate and term, choose a yearly or monthly view, and press Generate. The table shows every payment's split between principal and interest plus the running balance.
What the result means
Early payments are mostly interest and late payments are mostly principal. This is why paying extra early saves so much — every extra dollar avoids years of accumulated interest.
Frequently asked questions
Why is most of my early payment interest?
Interest is calculated on the current balance, which is highest at the start. As the balance falls, the interest portion of each payment shrinks.
Should I pay extra on my mortgage?
If your rate is higher than what you'd earn investing, and you have an emergency fund, paying extra is a safe, guaranteed return.
