30 Year Annuity Calculator
Planning for retirement or long-term financial goals often involves annuities—steady, recurring payments over time that grow with interest. Whether you're a personal finance enthusiast, retirement planner, or investor, estimating the future value of an annuity can help you make smarter financial decisions.
Our 30-Year Annuity Calculator makes this easy. Simply enter your annual contribution and expected interest rate, and the calculator will show you the total future value after 30 years. No spreadsheets or financial formulas required.
What Is an Annuity and Why Does It Matter?
An annuity is a financial arrangement where a person makes regular payments (typically yearly) into an account that grows over time with compound interest. Over the long term, annuities can accumulate significant wealth due to the power of compound growth.
This calculator specifically handles a fixed annuity with annual contributions over 30 years, showing you how your money will grow based on the interest rate you expect.
How to Use the 30-Year Annuity Calculator
Using the tool is quick, straightforward, and doesn't require any advanced financial knowledge. Follow these steps:
1. Enter Annual Payment ($):
This is the amount you plan to contribute once per year. For example, if you're contributing $5,000 annually to an IRA, enter 5000.
2. Enter Annual Interest Rate (%):
This is the expected annual rate of return. For example, if you anticipate a 6% return from your investments, enter 6.
3. Click “Calculate”:
The calculator uses the standard future value of annuity formula to give you the total value after 30 years.
4. View Your Results:
The tool will instantly show you the future value of your contributions, assuming consistent annual payments and the specified rate of return.
5. Reset If Needed:
Click “Reset” to clear all values and start over.
Example: How Much Will You Have After 30 Years?
Let’s say you contribute $6,000 per year into a retirement account, and your investments grow at an average annual rate of 7%.
- Annual Payment: $6,000
- Interest Rate: 7%
- Number of Years: 30
Result: You will have $566,764.44 after 30 years.
This is the power of compound interest working in your favor—your total contributions over 30 years amount to $180,000, but you gain nearly $386,000 in interest.

15+ Detailed FAQs About Annuities and the Calculator
1. What is the formula used in this calculator?
The future value formula used is:
FV = P × [(1 + r)^n – 1] / r
Where:
- FV = Future value
- P = Annual payment
- r = Annual interest rate (decimal)
- n = Number of years (30 in this case)
2. Is this a simple or compound interest calculation?
This calculator uses compound interest, assuming reinvestment of all earnings annually.
3. What kind of annuity does this represent?
A regular ordinary annuity, where payments are made at the end of each year.
4. Can I change the number of years?
Not in this version. It is fixed at 30 years. For customizable durations, use a more advanced annuity calculator.
5. Is this calculator suitable for monthly contributions?
No, it assumes annual contributions only. Monthly contributions would require a modified formula.
6. Can I include inflation in this calculation?
This version does not factor in inflation. For inflation-adjusted results, manually reduce your interest rate to a real rate of return.
7. Is the interest compounded annually?
Yes, compounding is assumed to occur once per year, matching the frequency of contributions.
8. Is this for fixed or variable annuities?
This models a fixed annuity with a consistent annual payment and constant interest rate.
9. What if I expect interest rates to change?
This tool assumes a constant rate. If you expect changes, consider averaging your projected rates or using spreadsheet modeling.
10. Can I use this for retirement planning?
Absolutely. This is ideal for estimating long-term retirement savings from consistent annual contributions.
11. Are taxes included?
No. This calculator provides gross future value, not accounting for taxes or penalties.
12. Can I account for fees or charges?
You can simulate that by reducing your annual interest rate to reflect net returns after fees.
13. What happens if I increase my contributions yearly?
This calculator assumes flat contributions. For increasing payments, use a growing annuity formula.
14. Is this tool accurate for large payments?
Yes, it works with any annual payment amount, as long as interest rate and period remain consistent.
15. How realistic is a 7% return?
Historically, a 7% average return is reasonable for diversified stock investments over long periods, but past performance isn’t guaranteed.
16. Can I download the results?
No export feature is built-in, but you can screenshot or copy results.
17. Does it show yearly breakdowns?
No. It shows only the final total after 30 years.
18. Can I include a starting balance?
Not in this tool. It assumes contributions start from zero.
19. How do I interpret the results?
The number shown is the total amount you'd have after contributing annually for 30 years, growing at your selected rate.
20. What’s the difference between this and a retirement calculator?
This tool focuses solely on future value from fixed yearly contributions. A full retirement calculator includes expenses, withdrawals, and inflation.
