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.

Key Financial Concepts Explained

Interest

Interest is the cost of borrowing or the earnings from savings. It is usually expressed as a percentage of the amount over time.

Compound vs Simple Interest

Simple Interest is calculated on the original cash amount only.
Compound Interest includes interest earned on previously accumulated interest.

Compound interest accelerates growth over time, and this calculator includes options for both when relevant.

Practical Example

Suppose you want to save for a major purchase. You deposit $5,000 into a savings account with an annual interest rate of 4%, compounded annually, and plan to leave it untouched for 10 years.

Using this finance calculator:

Future value ≈ $7,401
Total interest earned ≈ $2,401

By adjusting inputs, you can test different scenarios and timeframes.
