The growing annuity formula is a powerful financial tool used to calculate the future value of a series of periodic payments that increase at a constant rate. This formula is widely used in finance, accounting, and investment analysis. In this article, we will explore the growing annuity formula in Excel, its components, and provide step-by-step instructions on how to use it.
Understanding the Growing Annuity Formula
The growing annuity formula is an extension of the ordinary annuity formula, which calculates the future value of a series of periodic payments. The growing annuity formula takes into account the growth rate of the payments, which can be due to inflation, salary increases, or other factors. The formula is as follows:
FV = PMT x (((1 + g)^n - 1) / g) x (1 + r)^n
Where:
- FV = Future Value
- PMT = Periodic Payment
- g = Growth Rate
- n = Number of Periods
- r = Interest Rate
Using the Growing Annuity Formula in Excel
To use the growing annuity formula in Excel, you can use the FV function, which is a built-in function in Excel. The syntax for the FV function is as follows:
FV(rate, nper, pmt, [pv], [type])
Where:
- rate = Interest Rate
- nper = Number of Periods
- pmt = Periodic Payment
- [pv] = Present Value (optional)
- [type] = Payment Type (optional)
To calculate the future value of a growing annuity, you need to use the FV function in combination with the PMT function, which calculates the periodic payment. The PMT function has the following syntax:
PMT(rate, nper, pv, [fv], [type])
Where:
- rate = Interest Rate
- nper = Number of Periods
- pv = Present Value
- [fv] = Future Value (optional)
- [type] = Payment Type (optional)
Step-by-Step Instructions
Here are the step-by-step instructions to calculate the future value of a growing annuity in Excel:
- Enter the interest rate: Enter the interest rate as a decimal value in a cell.
- Enter the number of periods: Enter the number of periods as a whole number in a cell.
- Enter the periodic payment: Enter the periodic payment as a decimal value in a cell.
- Enter the growth rate: Enter the growth rate as a decimal value in a cell.
- Calculate the future value: Use the FV function to calculate the future value of the growing annuity.
Example:
- Interest Rate: 5% (cell A1)
- Number of Periods: 10 years (cell A2)
- Periodic Payment: $1,000 (cell A3)
- Growth Rate: 3% (cell A4)
Formula: =FV(A1,A2,A3,,0)*(1+A4)^A2
Result: $14,509.09
