Frequently Asked Questions
The annuity due version multiplies the result by (1 + k), reflecting the extra period of growth each beginning-of-period payment receives. This produces a higher future value compared to end-of-period payments.
Use it when you make increasing contributions at the start of each period — like beginning-of-year retirement deposits that grow annually with your salary. The formula captures both the payment growth and the early-deposit timing advantage.
The difference is the ordinary growing annuity FVA multiplied by the periodic rate. At typical rates (6-8%) over 20-30 years, beginning-of-period timing adds roughly 6-8% more to the final accumulated balance.
