🕊️ Financial PlanningFinancial independence: how to calculate your number
Financial independence is the point where your investments generate enough return to cover your living costs, without needing a salary. It does not necessarily mean stopping work — it means having the choice. The central number is how much capital you need, and it depends almost entirely on how much you spend per year. Here we go through the maths, and how Bangladeshi inflation, tax and the lack of a contributory state pension change the picture.
The 4% rule and your target number
A common rule of thumb says you can withdraw about 4% of a well-diversified portfolio in the first year and then adjust for inflation, and the money has historically lasted at least 30 years. Turned around, that means you need roughly 25 times your annual spending.
If you spend Tk 4,000,000 a year, the target number is about Tk 100,000,000. The rule is a simplification — it is based on long-run developed-market returns — and in a higher-inflation economy like Bangladesh's a more cautious 3-3.5% withdrawal, or holding some US-dollar assets, is worth considering.
Your savings rate decides the time
How quickly you reach independence depends less on your income and more on what share of it you save. Saving 15% of take-home pay takes roughly 40 years; saving 40% takes a bit over 20 years; saving 60% around 12-15 years. The reason is twofold: you build capital faster, and you get used to living on less, which lowers the target number.
Cutting fixed costs therefore has a double effect — every Tk 10,000 less in monthly spending both reduces what you need to save and reduces how large the final pot must be. In Bangladesh, housing, transport and school fees are usually the biggest fixed costs.
Inflation, tax and no state pension
For an individual, gains on listed shares are tax-free up to Tk 50 lakh a year and 15% above that; interest carries 10% TDS (15% without a TIN); cash dividends carry 10% TDS with the first Tk 50,000 exempt. Use figures after tax, and think in real terms after inflation, which has often run mid-single-digits.
There is no automatic contributory state pension for private-sector workers, so you cannot lean on one. The voluntary Universal Pension Scheme only pays from 60, and a provident fund and gratuity are paid when you leave the job — so if you want to stop earning well before 60 you need a separate, accessible portfolio to bridge the years.
Frequently Asked Questions
- How much capital do I need to be financially independent?
- As a rule of thumb, about 25 times your annual spending, based on the 4% rule. The number depends almost entirely on your spending level, not your income. In a higher-inflation economy a more cautious multiple (28-33 times) is sensible.
- Is the 4% rule safe for Bangladesh?
- It is a historical rule of thumb based mostly on US data. In a higher-inflation environment, and for a retirement that must last 40+ years, many people use a more cautious 3-3.5% withdrawal and hold some assets in US dollars to protect purchasing power.
- Can I retire early if my pension money is locked?
- A provident fund and gratuity are paid when you leave the job, and the Universal Pension only pays from 60. To stop earning before then you need a separate, accessible portfolio — mutual funds, shares, Sanchayapatra, property income — to live on.
