How to Plan for Your Retirement
Planning for retirement is one of the most critical financial tasks you will undertake. Our Retirement Savings Calculator helps you visualize your financial future by calculating how your savings can grow over time through the power of compound interest.
Understanding the Inputs
- Current & Retirement Age: These determine the time horizon for your investments. The longer the timeline, the more time your money has to compound.
- Current Savings: The starting principal amount you have already saved in 401(k)s, IRAs, or brokerage accounts.
- Monthly Contribution: The amount you consistently add to your savings every month. Consistency is key to building wealth.
- Annual Return: Historically, the stock market (S&P 500) has returned about 7-10% annually after inflation. A conservative estimate is often 6-7%.
The Power of Compound Interest Example
Consider an investor starting at age 30 who plans to retire at 65 (35 years to grow). If they start with $10,000 and contribute $500 per month at an 8% annual return:
- Total Contributions: $220,000
- Total Interest Earned: ~$970,000
- Final Balance: ~$1.19 Million
This example demonstrates that the majority of the retirement fund comes from interest, not just your direct contributions.
What is the 4% Rule?
The "Estimated Monthly Income" shown in this calculator is based on the 4% rule. This is a common rule of thumb suggesting that retirees can safely withdraw 4% of their total portfolio in the first year of retirement (adjusted for inflation thereafter) without running out of money for at least 30 years.
