Traditional IRA Calculator

A Traditional IRA is one of the most widely used retirement accounts in the US, and for good reason: it lets you contribute money before taxes are taken out, potentially lowering your tax bill today, while your investments grow tax-deferred until retirement.

Millions of people use Traditional IRAs to build retirement savings outside of a workplace plan, or alongside one. But because the tax benefit shows up now and the tax bill shows up later, it’s easy to lose track of the full picture — how big your balance could really get, and how much you might owe when you eventually withdraw it.

That’s exactly what a Traditional IRA Calculator is built to show. By entering your age, balance, contributions, and expected return, you get a clear projection of your future account value, your total tax-deferred growth, and the upfront tax savings your contributions provide — so you can plan with real numbers instead of guesswork.

What Is a Traditional IRA?

A Traditional IRA (Individual Retirement Account) is a retirement savings account that offers two key tax advantages: your contributions may be tax-deductible in the year you make them, and your investments grow tax-deferred — meaning you don’t pay taxes on gains, dividends, or interest until you withdraw the money.

Tax-Deferred Growth

Because you’re not taxed on gains each year, your full balance keeps compounding, uninterrupted, until withdrawal — often resulting in significantly more growth over decades compared to a taxable account.

Tax-Deductible Contributions

Depending on your income and whether you (or your spouse) are covered by a workplace retirement plan, some or all of your contribution may be deductible from your taxable income for that year — effectively lowering what you owe the IRS now.

Example: if you’re in the 24% tax bracket and contribute $7,000, a fully deductible contribution could reduce your tax bill by about $1,680 that year.

Annual Contribution Limits

The IRS sets a yearly cap on how much you can contribute across all your IRAs combined (Traditional and Roth together), with an additional “catch-up” amount allowed once you turn 50.

Withdrawal Rules

Withdrawals are taxed as ordinary income in the year you take them. Qualified withdrawals generally begin at age 59½.

Required Minimum Distributions (RMDs)

Unlike a Roth IRA, a Traditional IRA requires you to start withdrawing a minimum amount each year once you reach a certain age (currently 73 under current law), whether you need the income or not.

Early Withdrawal Penalties

Withdrawing funds before age 59½ generally triggers a 10% early withdrawal penalty on top of ordinary income tax, with a small number of IRS-defined exceptions.

What Is a Traditional IRA Calculator?

A Traditional IRA Calculator is a planning tool that projects your future account balance by combining your current savings, ongoing contributions, and expected investment growth over time.

It estimates your retirement savings by applying compound growth to both your existing balance and every future contribution, then totals them into a single projected balance at your chosen retirement age.

Investors should use it before opening or contributing to an IRA because it turns abstract “save more for retirement” advice into a concrete number — showing exactly how today’s contribution decisions could translate into tomorrow’s account balance.

How to Use the Traditional IRA Calculator

Traditional IRA Growth Formula

Future Value Formula

P is your present balance, r is your annual expected return, and n is the number of years until retirement.

Compound Interest Formula

A is the final amount, P is principal, r is the annual rate, n is the number of times interest compounds per year, and t is the number of years.

Tax Savings Formula

This is the amount your taxable income — and roughly your tax bill — is reduced by in the year you make a deductible contribution.

Example Calculation

Input	Value
Current age	35
Retirement age	65 (30 years)
Current balance	$25,000
Annual contribution	$7,000
Annual return	8%
Current tax rate	24%

Results

Output	Value
Growth of current balance ($25,000 × 1.08^30)	$251,568
Growth of contributions ($7,000/yr for 30 years)	$792,988
Future Traditional IRA balance	$1,044,556
Total contributions (initial + 30 years)	$235,000
Total investment earnings	$809,556
Estimated annual tax savings (24% × $7,000)	$1,680/year

Traditional IRA Contribution Limits

For 2026, the IRS set the combined IRA contribution limit (Traditional and Roth together) at $7,500, up from $7,000 in 2025. Savers age 50 or older can add a $1,100 catch-up contribution, for a total of $8,600.

Unlike a Roth IRA, anyone with taxable compensation can contribute to a Traditional IRA regardless of income — there’s no income cap on contributing. Income only affects whether your contribution is tax-deductible, and only if you (or your spouse) are covered by a workplace retirement plan.

2026 Deduction Phase-Out Ranges (If Covered by a Workplace Plan)

Filing Status	2026 Phase-Out Range (MAGI)
Single / Head of Household	$81,000 – $91,000
Married Filing Jointly (contributing spouse covered)	$129,000 – $149,000
Non-covered spouse married to a covered spouse	$242,000 – $252,000

If neither you nor your spouse is covered by a workplace retirement plan, your full contribution is deductible regardless of income.

Traditional IRA vs Roth IRA

Factor	Traditional IRA	Roth IRA
Tax treatment	Tax-deferred growth	Tax-free growth
Contribution deductions	Potentially deductible now	Never deductible
Withdrawals	Taxed as ordinary income	Tax-free (if qualified)
Income limits	None to contribute; deduction may phase out	Yes — contribution phases out at higher incomes
RMDs	Required starting at age 73	None during the original owner’s lifetime
Best for	Those expecting a lower tax rate in retirement, or wanting a deduction now	Those expecting a higher tax rate in retirement, or wanting tax-free withdrawals

Generally, a Traditional IRA tends to favor savers who want to lower their taxable income today and expect to be in a similar or lower tax bracket in retirement. A Roth IRA tends to favor younger savers or those expecting higher future income, who’d rather pay tax now at a known rate than risk a higher rate later.

Frequently Asked Questions

How much can I contribute to a Traditional IRA?

For 2026, you can contribute up to $7,500, or $8,600 if you’re 50 or older, across all your Traditional and Roth IRAs combined.

Is a Traditional IRA tax deductible?

It can be. If you’re not covered by a workplace retirement plan, contributions are fully deductible. If you are covered, your deduction phases out within IRS-set income ranges.

Can I have both a Traditional IRA and a Roth IRA?

Yes, you can contribute to both in the same year, but your combined contributions across both accounts can’t exceed the annual IRS limit.

What happens if I withdraw money early?

Withdrawals before age 59½ generally trigger a 10% early withdrawal penalty in addition to ordinary income tax, unless a specific IRS exception applies.

When do I have to pay taxes?

You pay taxes when you withdraw funds, not when you contribute or while the account grows — withdrawals are taxed as ordinary income in the year you take them.

What is the difference between a 401(k) and a Traditional IRA?

A 401(k) is employer-sponsored with typically higher contribution limits and possible employer matching, while a Traditional IRA is individually opened with lower limits but often broader investment choices.

Can I contribute after age 70?

Yes. The rule that once barred contributions after age 70½ was repealed — you can now contribute at any age as long as you have qualifying earned income.

What are RMDs?

Required Minimum Distributions are mandatory annual withdrawals the IRS requires starting at age 73, calculated based on your account balance and life expectancy.

Is a Traditional IRA better than a Roth IRA?

It depends on your tax situation. A Traditional IRA is often better if you want a deduction now and expect a similar or lower tax rate in retirement; a Roth IRA is often better if you expect a higher future tax rate.

Can I roll over a 401(k) into a Traditional IRA?

Yes, rolling a 401(k) into a Traditional IRA is common when changing jobs or retiring, and can typically be done tax-free if handled as a direct rollover.

How is Traditional IRA growth calculated?

Growth is calculated by compounding your existing balance and each future contribution at your expected annual return over the number of years until retirement.

Can inflation reduce my retirement savings?

Yes, inflation reduces the purchasing power of your future balance even as the nominal dollar amount grows, which is why many calculators show both a nominal and an inflation-adjusted projection.
