Frequently Asked Questions

How much money do I need to retire?

The rule of thumb is to save 25 times your annual expenses (based on the 4% withdrawal rule). If you spend $60,000/year, you need $1.5 million. This allows you to withdraw 4% annually without depleting your savings over a 30-year retirement.

What is the 4% rule?

The 4% rule states that you can safely withdraw 4% of your retirement portfolio in the first year, then adjust for inflation each year, with a high probability of not running out of money over a 30-year retirement.

When should I start saving for retirement?

As early as possible. Due to compound interest, money saved in your 20s is worth far more than money saved in your 40s or 50s. Even small contributions early on make a dramatic difference over decades.

How does Social Security affect my retirement income?

Social Security benefits are not included in this calculator. Your actual retirement income will be higher once you add Social Security benefits. You can estimate your benefit at ssa.gov.
