IRA Calculator

An Individual Retirement Account (IRA) Calculator helps estimate how much your retirement savings can grow over time based on contributions, investment returns, tax treatment, and account type (Traditional, Roth, SEP, or SIMPLE IRA).

What is an IRA?

An IRA (Individual Retirement Account) is a tax-advantaged retirement savings account regulated by the IRS under Publication 590. It helps individuals save for retirement while reducing or deferring taxes depending on the account type.

• Encourages long-term retirement savings
• Offers tax advantages depending on IRA type
• Includes Traditional, Roth, SEP, and SIMPLE IRAs

Types of IRA Accounts

Traditional IRA

A Traditional IRA allows tax-deductible contributions, and taxes are paid when funds are withdrawn in retirement.

• Tax-deductible contributions (subject to income limits)
• Taxed at withdrawal
• Required Minimum Distributions (RMDs) start at age 73

Roth IRA

A Roth IRA uses after-tax contributions, but qualified withdrawals in retirement are completely tax-free.

• No tax deduction on contributions
• Tax-free growth
• No RMD during owner’s lifetime

SEP IRA

A SEP IRA is designed for self-employed individuals and small business owners with high contribution limits.

• Employer-funded contributions
• High contribution limits (up to 25% of income or IRS cap)
• Immediate vesting

SIMPLE IRA

A SIMPLE IRA is designed for small businesses with fewer than 100 employees and includes employer matching contributions.

• Employee + employer contributions
• Lower administrative cost than 401(k)
• Higher early withdrawal penalties than Traditional IRA

How IRA Growth is Calculated

IRA growth depends on regular contributions, investment returns, and compounding over time.

Basic Formula (Future Value)

FV = P (1 + r)^t + contributions growth

• P = initial investment
• r = annual return rate
• t = number of years

Example IRA Growth

If you invest $5,000 per year for 30 years at a 7% return:

Estimated Retirement Value ≈ $500,000+ (depending on compounding and contribution timing)

Contribution Limits (Example)

IRA Type	Annual Contribution Limit (2026)
Traditional / Roth IRA	$7,500 (or $8,600 if age 50+)
SEP IRA	Up to 25% of income or $72,000
SIMPLE IRA	Up to $17,000 (+ catch-up contributions)
