Traditional IRA Calculator

Use this calculator to project a Traditional IRA balance and estimate after-tax retirement value.

What this calculator does

The Traditional IRA calculator estimates pre-tax growth and the after-tax value of withdrawals in retirement. It helps compare account balance with spendable retirement value.

It uses:

• current age and retirement age
• current Traditional IRA balance
• annual contribution
• expected retirement tax rate

Traditional IRA Formula

After-Tax FV = Pre-Tax FV × (1 - Retirement Tax Rate)

Where:

• Pre-Tax FV = projected IRA balance
• Retirement Tax Rate = expected tax rate on withdrawals
• After-Tax FV = estimated spendable value
• Contribution = annual amount added

Example calculation

If:

• Pre-tax balance at retirement = 500,000
• Retirement tax rate = 20%
• Tax owed = 100,000
• After-tax value = 400,000

Then:

• The account balance is 500,000
• The estimated spendable value is lower
• Taxes reduce the retirement value
• Planning should use after-tax figures

The after-tax Traditional IRA value is 400,000.

What is a Traditional IRA?

A Traditional IRA is an individual retirement account that may allow tax-deductible contributions. Withdrawals are generally taxed as ordinary income in retirement.

Why Traditional IRA planning matters

• separates pre-tax and after-tax value
• helps estimate future tax impact
• supports Roth comparison decisions
• improves retirement income planning

When to use this calculator

• projecting IRA growth
• estimating after-tax value
• comparing Traditional and Roth accounts
• planning retirement withdrawals

Common mistakes

• treating pre-tax balance as spendable cash
• ignoring required minimum distributions
• overlooking tax rate changes
• exceeding contribution limits

Traditional IRA vs Roth IRA

Traditional IRA tax benefits often happen upfront. Roth IRA tax benefits usually happen at withdrawal.

The better account depends on tax rates now and later.
