About This Calculator
A 401(k) is an employer-sponsored retirement account funded with pre-tax paycheck deductions. Many employers match a portion of your contributions — essentially free money.
Real-world example: Contribute 6% of your $80,000 salary and your employer matches 3% — that is $2,400/year of free retirement money.
