How to reach financial independence (FIRE)

The 4% rule and your freedom number

A popular rule of thumb: you can withdraw roughly 4% of your nest egg per year, meaning you need about 25× your annual expenses invested to be financially independent. Spend $40,000 a year? Your rough freedom number is about $1,000,000.

It's a starting estimate, not a guarantee. A good FIRE calculator refines it by inflating your current expenses to your target age, then working out the corpus needed so inflation-adjusted withdrawals last through your chosen life expectancy, given your expected return.

Your savings rate is the biggest lever

The single biggest driver of how soon you reach independence isn't your investment return — it's your savings rate, the share of income you don't spend. It works twice: a higher rate grows your nest egg faster and lowers the lifestyle that nest egg has to fund. Someone saving 50% of their income reaches independence dramatically sooner than someone saving 10%, even with identical returns.

Let compounding do the heavy lifting

Once high-interest debt is gone and an emergency fund is in place, investing is how money outpaces inflation. The biggest factor is time — the earlier you start, the more compounding works in your favour. A small amount invested consistently for decades typically beats a large amount started late.

Durable investing principles

• Time in the market beats timing the market. Consistent, regular investing tends to outperform trying to guess the highs and lows.
• Diversify. Spreading money across many holdings — for example, through broad low-cost index funds — reduces the risk that any single bet sinks you.
• Keep costs low. High fees compound against you just like interest does.
• Match risk to your timeline. Money you need soon belongs somewhere safe; money you won't touch for decades can ride out market swings.
