Understanding the differences and using our calculator to compare your options can help you maximize your retirement savings and optimize your tax strategy.

Understanding Retirement Accounts

What is a 401(k)?

A 401(k) is an employer-sponsored retirement savings plan that allows employees to contribute a portion of their salary on a pre-tax basis. Employers may also contribute matching funds, making 401(k)s one of the most valuable retirement savings tools available.

Key Features:

Employer-sponsored
Pre-tax contributions
Employer matching (often available)
Higher contribution limits
Automatic payroll deductions

What is an IRA?

An Individual Retirement Account (IRA) is a personal retirement savings account that you open and manage yourself. IRAs offer more investment options and flexibility than 401(k)s, but typically have lower contribution limits.

Key Features:

Individual account
More investment options
Lower contribution limits

Taxable accounts for additional savings

3. Tax Bracket Optimization

High Tax Bracket:

Focus on pre-tax contributions
