What is a Savings Longevity Calculator?

A "How Long Will My Money Last Calculator" is a vital financial tool used to determine how many years and months your current nest egg will sustain your lifestyle. Whether you are planning for early retirement or simply managing a windfall, understanding the depletion rate of your capital is essential for long-term financial security.

How to Use This Calculator

To get an accurate estimate, you need to provide three key pieces of information: your current total savings, the amount you plan to withdraw every month, and the average annual return you expect from your investments. The calculator accounts for compounding interest, which can significantly extend the life of your money if your returns are higher than your withdrawal rate.

Factors That Influence Your Money's Lifespan

While this tool provides a mathematical projection, several real-world factors can impact the actual outcome:

• Inflation: Over time, the purchasing power of your money decreases. A $2,000 withdrawal today may not buy the same amount of goods in 10 years.
• Market Volatility: Investment returns are rarely a steady line. A sequence of poor returns early in retirement (sequence of returns risk) can deplete savings faster than expected.
• Taxes: Depending on the type of account (401k, IRA, or brokerage), your withdrawals may be subject to income tax.

Frequently Asked Questions

What is the 4% rule?

The 4% rule is a popular benchmark suggesting that if you withdraw 4% of your initial retirement savings each year (adjusted for inflation), your money should last for at least 30 years.

Can my money last forever?

Yes. If your annual investment return is higher than your annual withdrawal amount, your principal balance will continue to grow, making your savings technically infinite.

Should I include Social Security?

When calculating your monthly withdrawal needs, you should subtract your Social Security or pension income from your total expenses. Only enter the amount you actually need to pull from your personal savings into this calculator.
