Can I use this calculator for different interest rates?
Yes, you can input any interest rate to see how it affects the future value of your annuity over time.
How does the number of payments affect the future value?
The more payments you make, the higher the future value will be, assuming a constant payment amount and interest rate.
Is there a maximum limit to the number of payments I can calculate?
No, this calculator can handle a wide range of payment numbers, but very high numbers might result in computational limitations or rounding errors.
Can I use this calculator for monthly contributions?
Yes, you can input the monthly contribution amount as the payment (P) and adjust the interest rate and number of payments accordingly to reflect a monthly schedule.
