Select either Annuity Due or Ordinary Annuity from the drop-down menu.
Select the frequency of your deposits or payments, whichever the case.
Enter the deposit/payment amount that corresponds to the selected annuity type.
Enter the number of years you plan to make the regular deposits/payments.
Click the "Calculate FV of Annuity" button. This will display the calculated future value, the total of your deposits/payments, the total interest earned, and a year-to-year growth chart.
Scrolling & Shrinking:
In order to scroll the calculator vertically you will need to swipe just outside of the calculator's dark-blue border, or use the window's far right-hand scroll bar, whichever is applicable to your device.
If the top section of the calculator becomes to tall for your viewport, tapping in the "Enter a problem..." field should reset the top section to its original height.
The Algebra Calculator is the only calculator on the site that I did not create myself. And since I did not create it, I don't have access to the code for fixing any issues you may be experiencing. So if you are having issues with the calculator, please visit the support page at Mathway.com for assistance.
