Future Value of Growing Annuity

The Future Value of a Growing Annuity (FVGA) is a financial formula used to calculate the future value of a series of cash flows that grow at a specified rate. This is particularly useful for investors and financial planners who want to determine the future worth of investments that contribute regular payments that increase over time.

Formula

The formula for calculating the Future Value of a Growing Annuity is:

FVGA = Pmt × [(1 + g)ⁿ - (1 + r)ⁿ] / (r - g)

• FVGA = Future Value of the Growing Annuity
• Pmt = Payment amount in the first period
• g = Growth rate of the annuity payments
• r = Interest rate (discount rate)
• n = Number of periods (years)

Use Cases

• Investment Planning: Helpful for estimating the future value of retirement savings where contributions increase over time.
• Education Savings: Useful for parents planning for children's future education costs that rise annually.
• Business Valuation: Used to assess the future cash flows of a business with growing revenue.
• Pension Funds: Important in calculating benefits that increase with inflation.

By understanding the Future Value of a Growing Annuity, investors and financial planners can make more informed decisions about their financial strategy and long-term goals.
