The App calculates the return from an sight deposit (on call account) from the investment capital, interest rate and duration (in days or months). The interest rates on current account accounts are often above the normal savings interest rate. You can always use the money at short notice!

Enter the investment amount, interest rate and investment period into the calculator and let it calculate how much return you can expect at the end of the period.

Many banks offer different interest rates and conditions for on call deposits. Just do the calculations before deciding to invest.
