What is Mortgage Statement Analyzer?
The Mortgage Statement Analyzer simulates your loan month by month: how each payment splits between interest and principal, the exact months to payoff with a calendar date, total interest over the remaining life - and an extra-payment scenario showing the money and months saved, all computed in your browser.
Key Benefits
- See the interest/principal split move over the life of the loan
- Concrete payoff date instead of a vague remaining term
- Extra-payment savings quantified in both money and months
- Catch impossible payments that never outgrow the interest
- Private - numbers stay on your device
Common Use Cases
- •Deciding whether a 100 extra per month is worth it on a 200k loan
- •Planning the end date of a mortgage before retirement
- •Comparing lump-sum bonuses against monthly extra payments
- •Understanding why early extra payments beat later ones

Frequently Asked Questions
Why is almost all of my early payment interest?
Interest is charged on the remaining balance, which is largest at the start. As the balance shrinks, the interest share falls and the principal share grows automatically.
How do extra payments save so much?
Every extra dollar goes entirely to principal. That reduces every future interest charge, so the loan ends earlier and the avoided months never accrue interest at all.
Why did I get a payment-too-small error?
If the payment does not exceed the monthly interest, the balance never decreases. The simulator detects this instead of looping forever.
Does this read my real mortgage statement?
It uses the same numbers - balance, rate, payment - that appear on the statement. The analysis itself runs locally in your browser.
