Future Value of Annuity Calculator finds what equal periodic payments grow to at an interest rate per period. It covers ordinary annuities and annuities due, with a growth chart, payment schedule and formula steps.
| Feature | What you get | Good for |
|---|---|---|
| Annuity types | Choose an ordinary annuity (payments at the end of each period) or an annuity due (payments at the start). The results for the two types can be compared. | Rent, lease and insurance payments versus loan payments and savings deposits |
| Inputs | Payment amount, interest rate per period as a percentage, number of periods, and 0 to 10 decimal places for the results. | Matching a monthly rate to monthly payments, or an annual rate to annual ones |
| Formulas | Ordinary annuity: FVA = C x ((1 + r)^n - 1) / r. Annuity due multiplies that result by (1 + r). | Checking homework or a spreadsheet model |
| Result breakdown | Shows the future value, total contributions, total interest and interest as a percentage of contributions. | Seeing how much of the final balance comes from interest |
| Growth chart | A stacked bar chart splits the balance over time into your contributions and the interest earned. | Seeing compounding build up over a long saving period |
| Payment schedule | A table lists the payment, interest earned and running balance for every period. | Tracing how a regular savings plan builds up |

What is Future Value of Annuity (FVA)?
The Future Value of an Annuity (FVA) is the total accumulated value of a series of equal payments made at regular intervals, invested at a given interest rate, at some point in the future. It shows how much your regular deposits will grow over time through the power of compound interest.
Annuities are common in everyday financial planning: regular contributions to retirement accounts (401k, IRA), monthly savings deposits, lease payments, insurance premiums, and loan payments are all examples of annuities.
Types of Annuities
There are two main types of annuities based on when payments are made:
- Ordinary Annuity (Annuity in Arrears): Payments are made at the end of each period. This is the most common type, including loan payments, bond coupon payments, and most savings contributions.
- Annuity Due: Payments are made at the beginning of each period. Examples include rent payments, insurance premiums, and lease payments.
Future Value of Annuity Formulas
Ordinary Annuity Formula
For payments made at the end of each period:
Annuity Due Formula
For payments made at the beginning of each period:
Where:
- FVA = Future Value of Annuity
- C = Payment amount per period
- r = Interest rate per period (as a decimal)
- n = Number of periods
How to Use This Calculator
- Enter payment amount (C): The fixed amount you will contribute each period.
- Enter interest rate (r): The rate of return per period as a percentage. Make sure this matches your payment frequency (monthly rate for monthly payments, annual rate for annual payments).
- Enter number of periods (n): How many payments you will make.
- Select annuity type: Choose Ordinary Annuity for end-of-period payments, or Annuity Due for beginning-of-period payments.
- Set precision: Select decimal places for your results.
- Calculate: View your future value, growth chart, payment schedule, and step-by-step calculations.
Understanding Your Results
Key Outputs
- Future Value: The total accumulated value at the end of all periods
- Total Contributions: The sum of all payments you made (C × n)
- Total Interest: The earnings from compound interest (FVA - Total Contributions)
- Interest as % of Contributions: Shows the growth multiplier of your money
Growth Chart
The stacked bar chart visualizes how your money grows over time, showing the split between your contributions (blue) and interest earned (green). The exponential growth pattern demonstrates the power of compound interest, especially visible in later periods.
Payment Schedule
The detailed schedule shows period-by-period breakdown of payments, interest earned, and running balance. This helps you understand exactly how your annuity builds over time.
Practical Applications
Retirement Planning
FVA is essential for retirement planning. If you contribute $500/month to a retirement account earning 7% annually for 30 years:
- Monthly rate: 7% ÷ 12 = 0.583%
- Periods: 30 × 12 = 360 months
- Total contributions: $180,000
- Future value: ~$609,985
College Savings
Parents can use FVA to plan 529 education savings. Regular monthly contributions, even modest ones, can grow substantially over 18 years.
Emergency Fund Building
Calculate how long it takes to build a target emergency fund by making regular deposits into a high-yield savings account.
Business Cash Flow Planning
Businesses use FVA to project the future value of regular revenue streams or to plan for capital expenditures through sinking funds.
Future Value of Annuity Table
The following table shows the Future Value Interest Factor of Annuity (FVIFA) for $1 per period. Multiply by your payment amount to find FVA:
| Periods | 3% | 5% | 7% | 10% | 12% |
|---|---|---|---|---|---|
| 5 | 5.3091 | 5.5256 | 5.7507 | 6.1051 | 6.3528 |
| 10 | 11.4639 | 12.5779 | 13.8164 | 15.9374 | 17.5487 |
| 15 | 18.5989 | 21.5786 | 25.1290 | 31.7725 | 37.2797 |
| 20 | 26.8704 | 33.0660 | 40.9955 | 57.2750 | 72.0524 |
| 25 | 36.4593 | 47.7271 | 63.2490 | 98.3471 | 133.3339 |
| 30 | 47.5754 | 66.4388 | 94.4608 | 164.4940 | 241.3327 |
Tips for Maximizing Annuity Growth
- Start early: Time is the most powerful factor in compound growth. Starting 10 years earlier can double your ending value.
- Increase contributions: Even small increases in regular payments compound significantly over time.
- Choose annuity due when possible: Making payments at the beginning of the period earns extra interest.
- Consistent investing: Regular contributions through market ups and downs provides dollar-cost averaging benefits.
- Reinvest earnings: Ensure interest and dividends are reinvested to maximize compound growth.
Frequently Asked Questions
What is Future Value of Annuity (FVA)?
The Future Value of an Annuity (FVA) is the total value of a series of equal periodic payments at a specified date in the future, assuming the payments are invested at a given interest rate. It represents how much your regular deposits will grow over time with compound interest.
What is the difference between ordinary annuity and annuity due?
An ordinary annuity (annuity in arrears) has payments made at the END of each period, while an annuity due has payments made at the BEGINNING of each period. Annuity due always results in a higher future value because each payment earns interest for one additional period. The formula for annuity due is: FVA(due) = FVA(ordinary) × (1 + r).
What is the annuity factor?
The annuity factor (also called Future Value Interest Factor of Annuity or FVIFA) is the multiplier that converts a single payment amount into the future value of an annuity. It is calculated as: [(1 + r)^n - 1] / r. This factor appears in FVA tables and represents how much $1 deposited at the end of each period will grow to after n periods at interest rate r.
How can I use FVA for retirement planning?
FVA is essential for retirement planning because it shows how regular savings grow over time. For example, if you contribute $500/month to a retirement account earning 7% annually for 30 years, you can calculate how much you will have at retirement. This helps set realistic savings goals and compare different contribution scenarios.
What happens if the interest rate is 0%?
When the interest rate is 0%, the future value of an annuity simply equals the total of all payments (C × n). There is no compound interest growth, so your money does not grow beyond what you contribute. Both ordinary annuity and annuity due yield the same result when the interest rate is zero.
How do I convert annual rate to monthly rate?
To convert an annual interest rate to a monthly rate, divide by 12. For example, 6% annual rate = 6% ÷ 12 = 0.5% monthly rate. Be sure to use the rate that matches your payment frequency.
