How to Use the Retirement Calculator

Plan Your Retirement Savings

Our retirement calculator helps you estimate how much money you'll have saved by retirement and how much monthly income you can expect to withdraw safely. It uses compound interest calculations to project your savings growth and applies the widely-accepted 4% rule to estimate sustainable withdrawal rates. This tool is perfect for planning your 401(k), IRA, or general retirement savings strategy.

Understanding the 4% Rule

The 4% rule is a retirement planning guideline that suggests you can withdraw 4% of your total retirement savings in the first year of retirement, then adjust that amount for inflation each subsequent year, without running out of money for at least 30 years. This rule is based on historical market returns and provides a conservative approach to retirement income planning.

For example, if you retire with $1,000,000 in savings, the 4% rule suggests you can safely withdraw $40,000 per year (or about $3,333 per month) in retirement.

Key Factors in Retirement Planning

Current Age & Retirement Age: The number of years until retirement determines how long your money can grow through compound interest.
Current Savings: Your existing retirement balance will continue to grow over time, even without additional contributions.
Monthly Contributions: Regular monthly contributions are crucial. Even small amounts can add up significantly over decades thanks to compound interest.
Expected Return Rate: Historical stock market returns average around 10% annually, but a more conservative 7% after inflation is commonly used for planning. Bonds and more conservative investments may return 3-5%.
Inflation: Inflation erodes purchasing power over time. Historical US inflation averages around 3% annually. The calculator shows both nominal and inflation-adjusted values.

Retirement Savings Tips

1. Start Early:

Time is your greatest asset. Due to compound interest, starting 10 years earlier can double or triple your final savings.

2. Maximize Employer Match:

If your employer offers 401(k) matching, contribute at least enough to get the full match—it's free money!

3. Increase Contributions Regularly:

Try to increase your retirement contributions by 1-2% each year or whenever you get a raise.

4. Diversify Your Investments:

Don't put all your eggs in one basket. Spread investments across stocks, bonds, and other assets appropriate for your age and risk tolerance.

Frequently Asked Questions

How much do I need to retire?

A common target is 25× your annual expenses (the inverse of the 4% rule). If you spend $50,000 per year, aim for a $1.25M nest egg. Adjust upward for early retirement or longer life expectancy, downward if you'll have Social Security or pension income.

What is the 4% rule for retirement withdrawals?

The 4% rule says you can withdraw 4% of your nest egg in year one of retirement, then adjust for inflation each year, and have a high probability of not running out of money over 30 years. It's a starting point, not a guarantee, and assumes a balanced portfolio.

How does compound interest grow retirement savings?

Compound interest means you earn returns on past returns, not just on your contributions. Saving $500/month for 40 years at 7% returns ~$1.3M, with $1.05M coming from compound growth alone. Time in the market is the single biggest factor.

Should I prioritize 401(k), IRA, or both?

First, contribute enough to your 401(k) to capture any employer match (it's free money). Next, max a Roth IRA if eligible ($7,000 in 2025). Then return to the 401(k) up to its limit ($23,500 in 2025). High earners may also need a backdoor Roth strategy.

What is the difference between a Roth and Traditional 401(k)?

Traditional contributions are pre-tax (you pay income tax on withdrawals in retirement). Roth contributions are after-tax (withdrawals are tax-free). Choose Roth if you expect to be in a higher tax bracket in retirement; Traditional if you expect to be lower.

How does inflation affect retirement savings?

Inflation erodes purchasing power. $50,000 today buys what $80,000+ will buy in 25 years at 3% inflation. Plan in 'real' (inflation-adjusted) terms by using long-term return assumptions of 4–5% above inflation rather than nominal stock-market averages of 7–10%.

When should I start saving for retirement?

Now. Saving $500/month from age 25 to 65 at 7% returns ≈ $1.3M. Starting at 35 cuts that nearly in half ($610K). Every decade of delay roughly doubles the monthly contribution required to hit the same target. Time compounds harder than contribution amount.
