About 401(k) Retirement Savings

A 401(k) is an employer-sponsored retirement savings plan that allows employees to contribute a portion of their wages to individual accounts. 401(k) plans are tax-advantaged, meaning the money you contribute is deducted from your taxable income, reducing your current tax burden.

Key Benefits
  • Tax Advantages: Contributions are made pre-tax, reducing your current taxable income.
  • Employer Matching: Many employers match a percentage of your contributions, which is essentially free money.
  • Compound Growth: Over time, your investments can grow significantly due to compound returns.
  • Automatic Savings: Contributions are automatically deducted from your paycheck, making saving easier.
Contribution Limits

The IRS sets annual contribution limits for 401(k) plans. For 2025, the contribution limit is $23,000 for those under 50, and $30,500 for those 50 and older (including catch-up contributions).

Tips for Maximizing Your 401(k)
  1. Contribute at least enough to get your full employer match
  2. Increase your contribution rate whenever you get a raise
  3. Consider your investment time horizon when selecting investment options
  4. Regularly review and rebalance your portfolio
  5. Avoid early withdrawals to prevent penalties and lost growth potential

Formula Used in the 401(k) Calculator

Future Value of Retirement Savings:

FV = PV × (1 + r)^n + PMT × [((1 + r)^n - 1) / r]

  • FV = Future Value at retirement
  • PV = Current 401(k) balance
  • r = Annual rate of return (as a decimal)
  • n = Number of years until retirement
  • PMT = Total yearly contribution (employee + employer)

FAQs

Is this calculator only for 401(k) plans?

While it focuses on 401(k) savings, the same concepts apply to other retirement vehicles. If you're exploring options, tools like a Roth IRA calculator or IRA retirement estimator can help with IRA tax benefits and savings projections.

Can I use this to plan my Required Minimum Distributions (RMDs)?

This calculator doesn’t perform RMD calculations, but it helps estimate the balance that RMDs are based on. For actual withdrawals, refer to an RMD calculator that follows current RMD rules.

Does it account for annuities or pensions?

No, but if you're considering guaranteed income in retirement, explore an annuity payout calculator or pension planning tool for additional retirement payout planning.

How accurate is the result?

The calculator provides a future retirement savings estimate based on the numbers you enter and common assumptions. Market performance and inflation may vary, so use it as a guide—not a guarantee.
