Flamingo FIRE: reach half, then let it finish

Flamingo FIRE means reaching half your full number, then stopping and letting compounding do the other half. At 8%, money roughly doubles in nine years. Half of €1,050,000 is €525,000, and it becomes the full number without another euro added.

The formula

Full FI number ÷ 2.

Assumptions: 4% withdrawal rate, 8% growth before inflation, age 35 targeting 60. Stated in full in the methodology.

Worked example: €3,500 a month

This is not a round number. It is what my own living costs were at the point passive income covered them, which is the moment I would call being free.

Half of the full FI number, then coast.

And here is how long that takes, by what you put in every month.

Look at what changes between those rows. The gap between them is a pay question, not an investing question, and that is the whole argument of this site. The calculator works out how much more you could be putting in without changing job.

Who it suits

People who want a clear halfway marker rather than an open-ended climb.

What I think of it

Flamingo is Coast FIRE with a rounder number and a fixed rate of doubling. It survives because halves are easy to hold in your head, and a target you can hold in your head is a target you keep. That is not a small thing. Most plans fail because people stop believing in them, not because the maths was wrong.

Questions

How long does the second half take?

At 8% before inflation, about nine years. At 5% after inflation, closer to fifteen. Which of those you use decides whether this is a plan or a hope.

The other eight
