How to Use This Tool
Follow these steps to get accurate Traditional IRA projections:
- Enter your current age and planned retirement age (must be older than your current age).
- Input your expected annual pre-tax contribution, and check the catch-up box if you are 50 or older (eligible for an extra $1,000 contribution).
- Add your current Traditional IRA balance (enter 0 if you have no existing balance).
- Enter your expected annual rate of return and select how often your investments compound (monthly, quarterly, or annually).
- Input your current marginal tax rate and expected marginal tax rate in retirement.
- Click Calculate to see your projected balance, tax savings, and growth breakdown.
- Use the Reset button to clear all fields and start over, or Copy Results to save your projection.
Formula and Logic
This calculator uses standard financial formulas for tax-deferred retirement accounts:
- Future Value of Lump Sum (existing balance): FV = P * (1 + r/n)^(nt), where P is current balance, r is annual rate of return (decimal), n is compounding periods per year, t is years until retirement.
- Future Value of Ordinary Annuity (annual contributions): FV = PMT * [ ((1 + r/n)^(nt) - 1) / (r/n) ], where PMT is annual contribution.
- Total Pre-Tax Balance: Sum of the two future values above.
- Total Tax Savings: Total contributions * (current marginal tax rate / 100), reflecting the tax deduction for Traditional IRA contributions.
- After-Tax Retirement Balance: Total Pre-Tax Balance * (1 - retirement marginal tax rate / 100), as withdrawals are taxed as ordinary income.
Current IRA balance defaults to 0 if left empty. All projections are estimates and do not account for fees, inflation, or changes in tax law.
Practical Notes
Traditional IRAs have specific rules that impact your results:
- Contribution limits for 2024 are $7,000 for individuals under 50, and $8,000 for those 50 or older. Contributions must be made by the tax filing deadline to count for the current year.
- Tax deductibility of contributions may be limited if you or your spouse have a retirement plan at work and your income exceeds IRS thresholds.
- Withdrawals before age 59.5 incur a 10% early withdrawal penalty plus income tax. Required Minimum Distributions (RMDs) start at age 73.
- Investment returns are not guaranteed; use a conservative rate (5-7%) for realistic projections.
Why This Tool Is Useful
This calculator helps you make informed retirement planning decisions:
- See how small increases in annual contributions add up over time due to compounding.
- Compare tax savings from deductible contributions against expected retirement tax rates.
- Adjust inputs to test different retirement timelines and contribution strategies.
- Plan for RMDs and tax liabilities in retirement by projecting after-tax balances.
Frequently Asked Questions
Is my Traditional IRA contribution tax-deductible?
Most individuals can deduct the full amount of their Traditional IRA contribution if they or their spouse do not have a workplace retirement plan. If you have a 401(k) or similar plan, deductibility phases out at higher income levels. Check IRS guidelines for current phase-out thresholds.
What is a good rate of return for a Traditional IRA?
Historical average returns for a diversified stock and bond portfolio range from 5% to 8% annually. Use a lower rate (5-6%) for conservative projections, or a higher rate (7-8%) if your portfolio is heavily weighted toward stocks.
When do I have to start taking money out of my Traditional IRA?
Required Minimum Distributions (RMDs) start at age 73 for individuals born between 1951 and 1959. For those born in 1960 or later, RMDs start at age 75. You must withdraw at least the minimum amount each year, or face a 25% penalty on the amount not withdrawn.

- Review your IRA portfolio annually to rebalance investments and adjust contributions as your income changes.
