How it works

Payment = amortising formula; interest = balance × monthly rate; principal = payment − interest; balance = balance − principal.

Example: $200,000 at 5% for 30 years → payment $1,074; first month interest $833, final months mostly principal.

When to Use This Calculator

Homeowners with an amortized mortgage — the standard structure for home loans in India and abroad — use this calculator to see where their money actually goes each month. In the early years of a 30-year loan, most of the payment is interest and the principal falls slowly; the month-by-month schedule makes that visible in a way a single EMI figure cannot. It is also the planning tool for extra payments: entering a recurring extra amount per month shows the new payoff date and the interest saved, which helps decide whether prepaying beats keeping the money in a deposit. Compare the two schedules side by side before committing to a prepayment plan, and check the loan documents for prepayment penalties first.

How to Use This Calculator

Step 1: Enter the mortgage amount, the annual interest rate and the term in years.
Step 2: Optionally enter an extra monthly payment to be applied to the principal.
Step 3: Open the schedule and scroll month by month to see the principal, interest and balance for each period.
Step 4: Compare the baseline schedule with the extra-payment schedule to see the interest saved and the shorter payoff date.

Worked Example

Take a $200,000 mortgage at 6% for 30 years. The monthly payment is about $1,199, and the first row of the amortization schedule shows interest of $1,000 for that month, because 200000 times 0.5% is 1,000, with only about $199 going to principal, leaving a balance of about $199,801. Scroll to year 20 and the split has reversed, with most of the payment reducing principal. Adding an extra payment of $100 per month visibly accelerates the balance decline.

Tips and Common Mistakes

•Tip 1: The schedule is monthly even though you think in years; read the payment number column to confirm the periodicity.
•Tip 2: The early rows are interest-heavy, so extra payments made in the first years save far more than the same money paid later.
•Tip 3: Check your loan documents for prepayment penalties before planning extra payments, since they can eat into the savings.
✗Mistake 1: Confusing the running balance with the amount of principal paid, since the balance is what remains, not what you have repaid.
✗Mistake 2: Adding extra payments to the rate or term fields instead of the dedicated extra-payment field, which skews the whole schedule.

Frequently Asked Questions

What is an amortization schedule?

It is a table showing each monthly payment split between interest and principal, and the remaining balance after every payment. Early payments go mostly to interest; later payments go mostly to principal.

Why is most of my early payment interest?

Interest is charged on the outstanding balance, which is largest at the start of the loan. As the balance shrinks, the interest portion shrinks and more of your fixed payment goes to principal.

How much total interest will I pay on a 30-year mortgage?

At typical rates, total interest can be roughly equal to the loan amount over 30 years. Enter your rate here and the schedule will show the exact lifetime interest for your numbers.

Can I see a printable amortization table?

Yes — the calculator shows a full year-by-year and payment-by-payment breakdown of principal, interest and balance that you can review on screen or print for your records.
