Use this tool to estimate monthly payments on compounded simple-interest loans. It can also generate amortization tables, so you can view how much of your monthly payment is going toward interest and principal on your loan.
InvestCalc can predict the future values of your investments based on annual interest rates, length of investment and annual contributions. You can also graph your predicted investment growth.
Compare two loans or investments at a time, or show total payments and interest for each loan. Like investment predictions, comparison information can be graphed. |
