Formula used

The calculator uses the following formula to determine your savings requirements:

Savings Required = (Annual Spending in Retirement / Expected Annual Return) * (1 - Expected Annual Return)

Where:

Annual Spending in Retirement: The amount you want to spend annually in retirement.
Expected Annual Return: The percentage you expect your investments to grow annually.

This formula is based on the 4% rule, which suggests that you can safely withdraw 4% of your portfolio annually in retirement. The formula adjusts for the expected annual return to determine how much you need to save to achieve financial independence.

Worked example

Let's walk through an example to illustrate how the calculator works. Suppose you want to achieve financial independence and have the following details:

Annual Spending in Retirement: $50,000
Expected Annual Return: 7%

Using the formula:

Savings Required = ($50,000 / 0.07) * (1 - 0.07) = $714,285.71 * 0.93 = $666,666.67

This means you need to save a total of $666,666.67 to achieve financial independence with an annual spending of $50,000 and an expected annual return of 7%. To reach this amount, you would need to save approximately $55,555.56 annually or $4,629.63 monthly.
