使い方

月々の返済額、総利息を計算し、住宅ローン・カーローン・個人ローンの返済スケジュールを確認できます。

  1. 1Enter the loan amount in the first field — this is the principal you are borrowing, without any down payment already made.
  2. 2Enter the annual interest rate as a percentage. For example, type 6.5 for a 6.5% APR loan.
  3. 3Enter the loan term and choose whether you are entering it in years or months using the toggle buttons.
  4. 4The monthly payment appears instantly in the large result card at the top. Below it, you can see the total amount repaid and total interest paid.
  5. 5Scroll down to the amortization table to see the first 12 months of payments broken down by principal and interest — notice how the interest portion decreases each month.
