Frequently Asked Questions

What is the difference between ordinary and annuity due?

Ordinary annuity payments occur at the end of each period. Annuity due payments occur at the beginning, so each payment earns one extra period of interest, resulting in a higher future value.

Can I use this for retirement planning?

Yes, this calculator is ideal for estimating the growth of regular retirement contributions such as 401k or IRA deposits.

What interest rate should I use?

Use a conservative long-term average based on your investment mix. For example, 6-7% for a balanced stock and bond portfolio, or 2-3% for savings accounts.

Does this calculator account for taxes or inflation?

No, this calculator shows nominal future value. You may want to reduce your expected rate of return to account for inflation or taxes.
