How much do I need to save to reach FIRE?

It depends on your annual living costs and the withdrawal rate you plan for. A common way to estimate the target capital is to divide annual costs by the withdrawal rate, for example 4 percent, which gives 25 times annual costs.

It depends on income, living costs and savings rate. A high savings rate shortens the timeline considerably, but the goal requires discipline over a long period and trades consumption today for freedom in the future.

What is the difference between FIRE and regular retirement saving?

The main difference lies in the time horizon and the savings rate. FIRE often targets a capital goal well before the usual retirement age, requiring a higher savings rate and a withdrawal rate that holds up over a longer withdrawal period.

What is a reasonable withdrawal rate?

A common starting point is around 4 percent per year, a historical rule of thumb rather than a guarantee. Many choose a lower withdrawal rate for extra margin, especially over a long withdrawal period.

Glossary

FIRE (Financial Independence, Retire Early)

A savings goal centred on building a capital base large enough for its returns to cover living costs, providing financial independence and the option to stop working early.

What it is

Capital that replaces a salary

FIRE is based on the idea that a sufficiently large invested capital base can generate an income that covers living costs, much like a salary does. The goal is reached through a combination of a high savings rate, disciplined investing and time for the capital to grow. Once the capital is large enough, work becomes optional rather than required.

Withdrawal rate: The share of the capital withdrawn each year. A lower withdrawal rate requires a larger capital base but provides a better margin against downturns.
Savings rate: The share of income that is saved. A higher savings rate shortens the time to reach the target capital, both through more capital going in and lower future living costs to cover.
Target capital: The capital required to cover annual living costs at a chosen withdrawal rate, often estimated by dividing annual costs by the withdrawal rate.

In practice

The path to the target capital

Most people pursuing FIRE combine a high savings rate with long-term capital invested in equity funds or individual stocks. The difference from traditional retirement saving lies in the time horizon. The goal is often reached well before the usual retirement age, which places higher demands on both the savings rate and a withdrawal rate that holds up over a longer withdrawal period.
