How to read the result
Lenders quote you principal and interest. Your bank account sees property tax, insurance and service charges as well, which is why the quoted payment and the real payment rarely match.
This calculator builds the full monthly figure and shows how much of the loan you hand over in interest across the whole term.
This page is set to Japan and prints JPY. Starts at ￥45,000,000 over 35 years at 1.3%. Every figure is a starting point you should overwrite with your own.

Questions people ask
- Why is my quoted payment lower than this?
- Quotes usually cover principal and interest only. Property tax and insurance are often collected with the payment but are not part of the loan.
- What does a 1% higher rate cost in Japan?
- At the 1.3% starting rate shown here, one extra percentage point adds roughly 10% to the monthly principal and interest, and far more over the full 35-year term. Raise the rate field and watch the total interest line.
- Is the currency here the one I pay in?
- This page is set to Japan and prints JPY. Switch country at the top of the form to change both the currency and the starting values.
