Profit, margin and markup from cost and price, or the price you need for a target margin or markup.
The monthly instalment on a loan, what the interest costs, and a year-by-year table.
Enter the amount, the yearly rate and the length, and see the equal monthly instalment banks quote, the total interest, and where each year's payments go between interest and principal. Numbers can be typed with commas, lakh grouping or Bangla digits, and the working is shown so you can check the figure rather than take it on trust.
It is the standard reducing-balance instalment, which is what most banks quote for a personal, car or home loan. A bank may add processing fees or insurance on top, and those are not part of this calculation.
Interest is charged on what is still owed, and at the start that is almost the whole loan. As the balance falls the interest share falls with it, which is what the yearly table shows.
