This table details all payments, monthly interest and principal amounts, as well as the remaining balance of the loan at any given time (just like a spreadsheet or a good calculator).

Some loans, such as global loans, may also have smaller routine payments over their lifetime, but this calculation only works for loans with a single payment of all principal and interest due at maturity.
