Financial freedom calculator
Your savings rate decides how long the journey takes. Results update as you type.
Everything invested for the long term.
After inflation. 4–6% is a common assumption.
4% is the classic rule of thumb.
Add your monthly income and spending to see your savings rate and years to financial freedom.
How it works
- 01 — Your yearly savings are income minus spending, and your savings rate is that amount as a share of income.
- 02 — Your freedom number is the pot that can fund your spending forever at your chosen withdrawal rate:freedom number = yearly spending ÷ withdrawal rate
- 03 — The calculator then grows what you have today month by month, adding your contributions and compounding your expected real return, until the balance reaches the target.
Worked example
Take-home pay of €4,000 a month with €2,500 of spending means €18,000 saved a year — a 37.5% savings rate. Yearly spending of €30,000 at a 4% withdrawal rate gives a freedom number of €750,000. Starting from €50,000 and earning 5% after inflation, that arrives in roughly 20 years — and trimming spending by €300 a month cuts several years off it.
Questions people ask
- What is a 'freedom number'?
- It is the amount invested that can cover your yearly spending indefinitely. At a 4% withdrawal rate it is your annual spending multiplied by 25 — so €30,000 a year of spending needs roughly €750,000.
- Why does the savings rate matter more than income?
- Your savings rate sets both how fast the pot grows and how small the pot needs to be. Spending less raises savings and lowers the target at the same time, which is why it moves the date twice as fast as a raise.
- What return should I assume?
- Use a real return, after inflation. A broadly diversified equity portfolio has historically returned around 5–7% after inflation over long periods, so 4–6% is a reasonable planning assumption.
- Is the 4% rule safe?
- It is a rule of thumb from long-run historical data, not a guarantee. Lower it to 3–3.5% if you plan a very long retirement or want more margin, which raises your target.
- Does the calculator store my numbers?
- No. Everything runs in your browser and nothing is sent anywhere or saved.
