What formula is used for calculating the growth of payments on an annuity due?

To calculate the growth of payments on an annuity due, the correct formula reflects the relationship between the growth rate of the payments and the discount rate used to calculate their present value.

The appropriate formula is designed to express how the perpetuity or annuity will grow when the payments are made at the beginning of each period, as is the case with an annuity due. It is crucial to adjust for both the growth of cash flows and the present value calculation.

The formula for the present value of an annuity due, reflecting the growth of payments, is formulated by taking into account the growth rate in the numerator, indicating the expected increase in cash flows, and the discount rate in the denominator, which adjusts these future cash flows back to present value terms.

By dividing the term with the growth rate by the term with the discount rate, the formula balances the effect of growth in payment versus the time value of money, underlining how the two interact in determining the present value of the annuity's payments.

Thus, this careful formulation captures the integral aspects of annuity due calculations, allowing for accurate financial planning and analysis in various contexts, like retirement funding or structured settlements.
