How This Calculator Works
Calculation methodology and assumptions
Projects Traditional IRA growth using annual compounding of contributions (capped at the 2026 IRS limit of $7,500, or $8,600 if 50+) at your expected return. If you're covered by a workplace retirement plan, the deduction phases out over the IRS's MAGI range for your filing status; if not covered (and your spouse isn't either), the full contribution is always deductible. Withdrawals are taxed as ordinary income, so the after-tax value applies your expected retirement tax rate to the full pre-tax balance.
How to Use This Investment & Retirement Calculator
- 1
Enter your initial investment
Input the lump sum you plan to invest today. This is your starting principal that will begin compounding immediately.
- 2
Set your monthly contribution
Enter the amount you plan to add each month. Consistent contributions accelerate growth through dollar-cost averaging.
- 3
Input expected return and time horizon
Set your expected annual return (7–10% for stocks historically, 4–6% for bonds) and investment period. Longer time horizons amplify compounding effects dramatically.
- 4
Review the growth projection
The results show your total invested amount, earnings from compound growth, and a year-by-year projection table showing how your money grows over time.
Example Calculation
How does compound interest build wealth over time?
Starting with $10,000 and adding $500/month at an 8% average annual return for 30 years: Your total contributions would be $190,000 ($10K initial + $180K in monthly deposits). But with compound growth, your portfolio would grow to approximately $745,000.
Result: Compound interest generated $555,000 in earnings on top of your $190,000 in contributions — nearly 75% of the final value came from returns, not deposits. Starting 5 years later would reduce the final amount by roughly $230,000. Time in the market is the most powerful factor in wealth building.
What Affects Your Results
Rate of Return
Even small differences compound massively over time. 7% vs. 8% over 30 years on $100K means a difference of $200K+. Asset allocation drives your expected return.
Time Horizon
Compounding accelerates exponentially. Most of your wealth is generated in the final years — a 30-year investment earns more in its last 5 years than its first 15.
Contribution Consistency
Regular monthly investments (dollar-cost averaging) smooth out market volatility and ensure you're always buying — including during dips when prices are low.
Fees & Expenses
A 1% annual fee vs. 0.1% fee on a $500K portfolio costs you $4,500/year extra. Over 30 years, high fees can consume 25–30% of potential returns. Use low-cost index funds.
Tips & Best Practices
- Start early. Thanks to compounding, $200/month invested from age 25 to 65 at 8% returns grows to ~$700K. Waiting until 35 cuts that to ~$300K — a $400K penalty for the 10-year delay.
- Don't try to time the market. Research consistently shows that time in the market beats timing the market. Missing the 10 best trading days over 20 years can halve your returns.
- Consider tax-advantaged accounts first: 401(k) (especially with employer match), IRA, HSA. These reduce your tax drag — a 25% tax bracket investor keeps more in a tax-deferred account.
- Rebalance annually. If stocks outperform and grow from 80% to 90% of your portfolio, rebalancing back to 80% locks in gains and manages risk.
- Factor in your state's tax treatment of investment income. Some states exempt certain investment income or have lower rates on capital gains.

Our editorial standardsFrequently Asked Questions
What is the Traditional IRA contribution limit for 2026?
The IRA limit for 2026 is $7,500 ($8,600 if 50 or older) — a combined limit shared with Roth IRA contributions.
Is my Traditional IRA contribution tax-deductible?
If neither you nor your spouse is covered by a workplace retirement plan (like a 401(k)), your full contribution is deductible regardless of income. If you ARE covered, the deduction phases out between $81,000-$91,000 MAGI for single filers (2026), or $129,000-$149,000 for married couples filing jointly where the contributor is covered.
How are Traditional IRA withdrawals taxed?
Withdrawals from a Traditional IRA in retirement are taxed as ordinary income at your tax rate in the year you withdraw — unlike a Roth IRA, which is tax-free. You must also begin Required Minimum Distributions (RMDs) starting at age 73; see our RMD Calculator.
