Future Value of Annuity
Breakdown:
Total Principal Paid: $0.00
Total Interest Earned: $0.00
Number of Payments: 0
Formula Used:
For Ordinary Annuity: FV = PMT * [((1 + i)^n – 1) / i]
For Annuity Due: FV = PMT * [((1 + i)^n – 1) / i] * (1 + i)
Where PMT is the payment per period, i is the interest rate per period, and n is the total number of periods.

What is a Future Value of Annuity Calculator?
A find future value of annuity calculator is a financial tool designed to determine the future worth of a series of equal payments (an annuity) made over a specified period, assuming a certain rate of return or interest rate. It's based on the time value of money principle, which states that money available now is worth more than the same amount in the future due to its potential earning capacity. This calculator helps you understand how regular savings or investments will grow over time when compounded interest is factored in.
Individuals planning for retirement, saving for a large purchase (like a house down payment or college education), or anyone making regular investments can benefit greatly from using a find future value of annuity calculator. It provides a clear projection of potential growth, aiding in financial planning and decision-making.
Common misconceptions include thinking that the future value is simply the sum of all payments. However, a find future value of annuity calculator correctly includes the compound interest earned on those payments over time, which significantly increases the final amount.
Future Value of Annuity Formula and Mathematical Explanation
The future value of an annuity is calculated using specific formulas depending on whether the payments are made at the end (ordinary annuity) or the beginning (annuity due) of each period.
1. Ordinary Annuity (Payments at the end of each period):
The formula is:
FV = PMT * [((1 + i)^n – 1) / i]
2. Annuity Due (Payments at the beginning of each period):
The formula is:
FV = PMT * [((1 + i)^n – 1) / i] * (1 + i)
Variable Explanations:
- FV: Future Value of the annuity – the total amount you will have at the end of the period.
- PMT: The amount of each equal payment made per period.
- i: The interest rate per period (annual rate divided by the number of compounding periods per year).
- n: The total number of periods (number of years multiplied by the number of compounding periods per year).
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| FV | Future Value | Currency ($) | Calculated |
| PMT | Periodic Payment | Currency ($) | 0+ |
| i | Interest Rate per Period | Percentage (%) or Decimal | 0 – 0.2 (0% – 20%) per period |
| n | Number of Periods | Count | 1 – 500+ |
| Annual Rate | Annual Interest Rate | Percentage (%) | 0 – 25% |
| Years | Number of Years | Count | 1 – 50+ |
The term `((1 + i)^n – 1) / i` is the future value interest factor for an ordinary annuity (FVIFA), which represents the sum of the compound growth factors for each payment.
Practical Examples (Real-World Use Cases)
Example 1: Retirement Savings
Sarah saves $500 every month for her retirement. She invests this in an account that yields an average annual return of 7%, compounded monthly. She plans to do this for 30 years. She makes payments at the end of each month (Ordinary Annuity).
- PMT = $500
- Annual Interest Rate = 7%
- Number of Years = 30
- Compounding/Payment Frequency = Monthly (12 times a year)
- Type = Ordinary
Using the find future value of annuity calculator: i = 0.07/12 = 0.0058333, n = 30 * 12 = 360. FV = 500 * [((1 + 0.07/12)^360 – 1) / (0.07/12)] ≈ $608,913.43. Sarah will have approximately $608,913.43 after 30 years.
Example 2: Saving for a Down Payment
David wants to save for a house down payment over 5 years. He decides to save $1000 at the beginning of each quarter into an account with a 4% annual interest rate, compounded quarterly.
- PMT = $1000
- Annual Interest Rate = 4%
- Number of Years = 5
- Compounding/Payment Frequency = Quarterly (4 times a year)
- Type = Annuity Due
Using the find future value of annuity calculator: i = 0.04/4 = 0.01, n = 5 * 4 = 20. FV = 1000 * [((1 + 0.01)^20 – 1) / 0.01] * (1 + 0.01) ≈ $22,239.29. David will have about $22,239.29 for his down payment.
How to Use This Future Value of Annuity Calculator
Our find future value of annuity calculator is designed for ease of use:
- Enter Regular Payment Amount: Input the amount you plan to save or invest regularly per period.
- Enter Annual Interest Rate: Input the expected annual interest rate your investment will earn.
- Enter Number of Years: Specify the total duration in years you will be making these payments.
- Select Compounding & Payment Frequency: Choose how often the interest is compounded and payments are made (e.g., Monthly, Quarterly, Annually). For simplicity, our calculator assumes payment frequency matches compounding frequency.
- Select Type of Annuity: Choose 'End of Period' if payments are made at the end of each period, or 'Beginning of Period' if at the start.
The calculator will instantly update the Future Value, Total Principal Paid, and Total Interest Earned. The growth table and chart will also update to visualize your annuity's growth. Use these results from the find future value of annuity calculator to see if your saving plan aligns with your financial goals.
Key Factors That Affect Future Value of Annuity Results
Several factors influence the final amount calculated by a find future value of annuity calculator:
- Payment Amount (PMT): Higher regular payments lead to a significantly higher future value.
- Interest Rate (i): A higher interest rate results in more compound interest earned, substantially increasing the future value, especially over long periods.
- Number of Periods (n): The longer the investment period, the more time for compounding to work, leading to exponential growth in the future value.
- Compounding Frequency: More frequent compounding (e.g., monthly vs. annually) at the same nominal annual rate results in slightly higher effective interest and thus a higher future value.
- Type of Annuity (Ordinary vs. Due): An annuity due (payments at the beginning) will have a higher future value than an ordinary annuity (payments at the end) because each payment earns interest for one extra period.
- Inflation: While not directly in the formula, inflation erodes the purchasing power of the future value. It's important to consider the real rate of return (interest rate minus inflation rate). Our find future value of annuity calculator shows the nominal future value.
- Taxes and Fees: Investment returns may be subject to taxes, and investment vehicles might have fees, which can reduce the net future value. These are not explicitly factored into the basic formula.
Frequently Asked Questions (FAQ)
An ordinary annuity has payments made at the end of each period, while an annuity due has payments made at the beginning of each period. This means annuity due payments earn interest for one extra period compared to ordinary annuity payments, resulting in a higher future value.
More frequent compounding (e.g., monthly instead of annually) leads to a slightly higher future value because interest is calculated and added to the principal more often, earning interest on interest sooner.
No, this find future value of annuity calculator is designed for annuities with equal, regular payments. For irregular payments, you would need a more complex cash flow analysis.
This calculator determines the nominal future value based on the given interest rate. It does not adjust for inflation. To find the real future value in today's purchasing power, you would need to discount the nominal future value by the expected inflation rate.
This calculator assumes a constant interest rate. If you expect the rate to change, you might need to calculate the future value in segments for each period with a constant rate or use more advanced tools.
The mathematical calculation is accurate based on the inputs. However, the actual future value of real-world investments depends on the actual interest rates achieved, which can vary.
No, this calculator is for the future value of investments or savings (annuities). For loans, you would typically use a present value calculator or a loan amortization calculator.
A perpetuity is an annuity that continues forever. It's not directly calculated with this tool, which assumes a finite number of periods, but the concept is related to annuities.
