FIRE calculators built on your country's own rules
Most FIRE calculators quietly assume you are American. These do not. Each one runs on its own country's pension system, retirement accounts and currency, because the rules that decide when you can actually retire are national, not universal.
Why does a country-specific calculator matter?
The 4% rule travels well. Almost nothing else does. Two people with identical savings and identical spending can face very different retirement dates depending on where they live, and the reasons are structural rather than cultural.
- When you can touch your own money. Australia's preservation age, Singapore's CPF lock until 55, Malaysia's EPF at 50, Ireland's pension access at 60, the UK's at 57. In every case the money exists but is unreachable, so early retirement depends on a bridge fund sitting outside the system.
- What the state gives back. New Zealand pays NZ Super to everyone at 65 regardless of wealth, which meaningfully lowers the target. Australia means-tests the Age Pension so hard that most early retirees will not see it. South Africa's grant is means-tested to the point of irrelevance for this audience. The UAE offers expatriates nothing at all.
- What the tax system takes while you wait. The Netherlands taxes the portfolio itself through Box 3 rather than taxing gains, which raises the number you need by a large margin. Germany's Vorabpauschale creates an annual drag on accumulating ETFs. Ireland's eight-year deemed disposal does something similar. None of these appear in a generic calculator.
Each calculator states its assumptions on the page and links the government source for every rule it relies on, so you can check the workings rather than trust them. If a figure could not be verified from a primary source, we left it out and said so.
Comparing countries rather than planning in one? The FIRE number by country study puts 162 countries on a single price-adjusted scale, and the US state study does the same across all 50 states and DC.
Common questions
Why can't I just use a US FIRE calculator?
Because the rules that decide when you can reach your own money are national rather than universal. Australia has a preservation age, Singapore locks CPF until 55, Malaysia's EPF opens at 50 and Ireland's pensions at 60. In each case the money exists but is unreachable, so an early retirement depends on a bridge fund sitting outside the system. A generic calculator can hand you a total that is arithmetically right and practically unreachable.
Do all the country calculators use the same math?
Yes. Every calculator here runs on one shared engine: your target is annual spending divided by your withdrawal rate, discounted back to today at your real return, where the real return is your nominal return minus inflation minus fees. What changes between countries is the currency, the state pension offset and the default assumptions. The formulas and defaults are set out in full on how our calculators work.
Which withdrawal rate do the country calculators use?
Most default to 4%, the rate that comes from Bengen's 1994 paper and the Trinity study that followed it. Some do not. The India calculator defaults to 3.5% and the Australia calculator to 3.75%. Every page exposes the rate as a slider so you can see what the assumption is doing to your target.
How current are the figures on each country page?
Each country page links the regulator or government department that sets each figure, so you can check whether it has moved since we wrote it. Contribution caps, access ages and state pension rates all change on their own national calendars. The constants that apply across the site, including the tax year 2026 United States retirement plan limits, are collected on how our calculators work.
