FIRE is a spending problem before it is an investing problem
Two people with the same salary can have completely different FIRE dates because the savings rate controls both sides of the equation: less spending means more money invested today and a smaller portfolio needed later.
Frequently asked questions
What does Financial Independence, Retire Early mean?+
It means building enough invested assets that withdrawals can cover your expenses, making paid work optional before traditional retirement age.
How is the FIRE number calculated?+
The common shortcut is annual expenses divided by your safe withdrawal rate. At 4%, that is 25x annual expenses; at 3.33%, it is about 30x.
Should I use 3% or 4%?+
Use 4% for a traditional 30-year US-style retirement assumption. Use 3-3.5% for longer early-retirement timelines, higher inflation uncertainty, or more conservative planning.
