How much money do you need to retire comfortably in the US?

Most Americans need between $1 million and $3 million to retire comfortably, depending on lifestyle, location, healthcare costs, and retirement age. The exact amount varies based on individual financial goals and expected expenses.

What is the 4% rule in retirement planning?

The 4% rule suggests retirees can withdraw 4% of their retirement savings annually with a high probability of their money lasting 30 years. For example, if you need $100,000 per year, you may need $2.5 million in savings.

Is $2 million enough to retire in the US?

$2 million may be enough for many retirees, especially if Social Security benefits and other income sources are included. However, required savings depend on annual expenses, inflation, healthcare costs, and investment returns.

How much should I save each month for retirement?

The amount you should save monthly depends on your retirement goal, age, and expected investment return. For example, to accumulate $2 million in 25 years at a 7% annual return, you may need to invest around $2,500 to $3,000 per month.

Does Social Security reduce how much I need to save?

Yes, Social Security benefits can reduce the amount of savings required. If Social Security covers part of your annual expenses, your retirement portfolio only needs to generate the remaining income.

Investment Calculator

An investment calculator helps you estimate how your money can grow over time based on the initial investment amount, expected rate of return, and investment period.

This tool is designed to provide a clear projection of potential growth using compound interest calculations. It allows you to see how consistent returns and time can impact long-term wealth accumulation.

How This Investment Calculator Works

This calculator uses standard compound interest formulas to estimate how an investment may grow over time.

Compound Interest Formula:

A = P (1 + r/n)^(nt)

Where:

A = Final investment value
P = Initial investment (principal)
r = Annual interest rate (decimal)
n = Number of times interest compounds per year
t = Number of years invested

The calculator applies this formula automatically to generate your estimated future value.

Why Time Matters in Investing

Time is one of the most powerful factors in investment growth. The longer your money remains invested, the greater the impact of compounding.

For example:

If you invest $5,000 at 7% annually for 10 years, your investment may grow to approximately $9,835.

If you keep the same investment for 20 years, it could grow to around $19,348.

This demonstrates how extended time horizons can significantly increase total returns.

Simple Interest vs. Compound Interest

Simple interest is calculated only on the original principal amount

Compound interest is calculated on both:

The original principal
Previously earned interest

Most long-term investments rely on compound growth, which accelerates returns over time.

This calculator focuses on compound interest scenarios commonly used in investment planning.

Example Investment Scenarios

Scenario 1: Moderate Growth

Initial Investment: $10,000
Annual Return: 6%
Duration: 15 years

Estimated Future Value: Approximately $23,965

Scenario 2: Long-Term Growth

Initial Investment: $15,000
