What is the 25x rule in FIRE?

The 25x rule suggests that 25 times your annual expenses is a reliable FIRE number, assuming a 4% withdrawal rate.

How much do I need to save if I want to spend $50,000 annually in retirement?

Using the 25x rule, your FIRE number would be $1,250,000 (25 * $50,000).

Can I retire early on $40,000 annual salary?

Yes, it's possible. If you save aggressively, for example, 70% of your income, and achieve a 7% annual return, you could potentially reach a FIRE number of $1,000,000 in about 15 years, starting from zero.

How does geoarbitrage impact my FIRE number?

By reducing your annual expenses through geoarbitrage, you can significantly lower your FIRE number. For instance, if you can cut your expenses from $60,000 to $40,000 by moving to a lower-cost area, your FIRE number would decrease from $1,500,000 to $1,000,000.

Calculating Your FIRE Number with the 25x Rule

To determine your FIRE number, you can use the 25x rule, which suggests that 25 times your annual expenses is a reliable target for retirement savings. For example, if you want to spend $40,000 per year, your FIRE number would be $1,000,000 (25 * $40,000). This rule assumes a 4% withdrawal rate, which is considered sustainable for long-term retirement portfolios.

Applying the 25x Rule to Different Annual Spends

Let's calculate the FIRE numbers for different annual spends using the 25x rule:

$40,000 annual spend: $1,000,000 (25 * $40,000)
$60,000 annual spend: $1,500,000 (25 * $60,000)
$80,000 annual spend: $2,000,000 (25 * $80,000)

These calculations demonstrate how the 25x rule can be applied to different income levels to determine a target FIRE number.

Worked Calculation Example

Suppose you want to spend $60,000 per year in retirement and you start saving $30,000 per year. Assuming an average annual return of 7% on your investments, you can calculate your progress towards your FIRE number as follows:

Year 1: $30,000 (savings) * 1.07 (1 + 0.07 return) = $32,100
Year 2: $32,100 + $30,000 (savings) = $62,100 * 1.07 = $66,457
Year 3: $66,457 + $30,000 (savings) = $96,457 * 1.07 = $103,139

Continuing this calculation for 20 years, you can determine if you will reach your FIRE number of $1,500,000.
