To use this calculator, enter the loan amount (don’t use commas or dollar signs), loan percentage rate, and the number of monthly payments in the life of the loan. Click the “Calculate Monthly Payment” button, and the amount of the monthly payment will appear. For a printable amortization schedule, click the “Show Amortization Schedule” button. If you wish to see the results of making a regular extra monthly payment, enter the desired amount, and click the amortization button again.
To use this calculator, choose either a one-time beginning balance, or a periodic contribution, and enter the appropriate amount, as well as the interest rate. (Don’t use commas, dollar signs or percent signs.) In the field labeled “Compounding”, enter the number of times per year the interest is compounded. For example, enter 12 for monthly compounding. If the interest is compounded continuously, put a check in the box labeled “Continuous”. Enter the number of years that the investment will be held, and click the button labeled “Compute Value”.
To create a table showing periodic growth of the investment, click the button labeled “Create Table”. Please note that the answer at the bottom of the table may be different from the one on this page, because of repeated rounding necessary to make the table. The final answer on this page will be more accurate. Also, you will not be able to make a table if the interest compounds continuously, since there would have to be an infinite number of rows in the table.
