## Annuity Due: Definition, Calculation, Formula, and Examples

Welcome to our finance blog! In this article, we will explore the concept of annuity due, covering everything from its definition to the calculation formula. Whether you are a finance enthusiast or simply curious about this financial term, we’ve got you covered!

## Key Takeaways:

- Annuity due is a type of cash flow stream where payments are made at the beginning of each period.
- The formula for calculating the future value of an annuity due includes an additional factor to account for the earlier cash inflows.

So, let’s start by understanding what exactly an annuity due is. An annuity due is a series of cash flows or payments made at the **beginning** of each period, as opposed to ordinary annuities where payments are made at the end of each period. This slight difference in timing can have a significant impact on the overall value of the annuity.

## Calculation of Annuity Due:

Calculating the future value of an annuity due requires a specific formula. The formula takes into account the payment amount, interest rate, and the time period over which the annuity will be paid. The formula to calculate the future value of an annuity due is:

FV = P * [(1+r) * ((1+r)^n – 1) / r]

Where:

- FV is the future value of the annuity due.
- P is the payment amount made at the beginning of each period.
- r is the interest rate per period.
- n is the number of periods.

Let’s consider an example to further illustrate the concept. Suppose you decide to invest $1,000 at the beginning of each year in an annuity due for a period of 5 years, with an annual interest rate of 6%. Using the formula, we can calculate the future value of this annuity as follows:

FV = $1,000 * [(1+0.06) * ((1+0.06)^5 – 1) / 0.06]

After performing the calculation, we find that the future value of the annuity due will be approximately $6,737.72.

## Conclusion:

Annuity due is an important concept in finance that involves a series of cash flows or payments made at the beginning of each period. The key takeaway from this article is that the timing of payments can make a significant difference in the overall value of an annuity. By understanding the calculation formula and examples provided, you can gain a deeper insight into annuity due and its financial implications.
