Part of the [FIRE in India](/fire) guide. The [retirement and FIRE planner](/tools/retirement-planner) shows your Coast FIRE number and flags whether you have already cleared it.

## The idea

Full FIRE is a demanding target. Coast FIRE is a much nearer one, and it changes your life sooner.

Coast FIRE is the amount you need invested **today** such that, with no further retirement contributions at all, compounding alone carries it to your full FIRE number by your target retirement age.

You still need income to live on. What you no longer need is to save for retirement. Every rupee beyond your living costs becomes genuinely yours to spend, or to redirect at something else entirely.

## Why it matters more than it sounds

Most people treat retirement saving as a permanent obligation, something they will be doing until the day they stop working. Coast FIRE reframes it as a task with a completion date.

Once you have crossed it, several things become available that were not before. You can take the lower-paid job that interests you more. You can move to part-time or contract work. You can start something of your own without the retirement clock running against you. You can take a year off. None of these require having reached full financial independence -- they only require that your retirement is already funded and no longer needs feeding.

That psychological shift is why Coast FIRE gets called the most underrated milestone in the movement.

## The calculation

Coast FIRE runs the compounding formula backwards:

```
Coast FIRE number = FIRE number / (1 + r) ^ n
```

Where `r` is your expected annual return before retirement and `n` is the years until your target retirement age.

Worked through, with a INR 6 crore FIRE number, a 12% expected return and retirement at 60:

| Your age | Years to 60 | Coast FIRE number |
|---|---|---|
| 30 | 30 | ~INR 20 lakh |
| 35 | 25 | ~INR 35 lakh |
| 40 | 20 | ~INR 62 lakh |
| 45 | 15 | ~INR 1.1 crore |
| 50 | 10 | ~INR 1.9 crore |

The top row is the striking one. At 30, roughly INR 20 lakh invested and left completely alone compounds to INR 6 crore by 60. That is a reachable figure for a mid-career professional, and it is about 3% of the eventual target.

That is not a trick, it is what thirty years of compounding at 12% does -- it multiplies by roughly 30. It also shows exactly why the first decade of investing matters so disproportionately, and why starting at 25 with modest amounts beats starting at 40 with large ones.

## The assumptions that decide whether it holds

Coast FIRE is more sensitive to its inputs than full FIRE, because it depends entirely on a long uninterrupted compounding runway.

**Return assumption.** The number scales sharply with `r`. At 12% over 30 years the multiplier is about 30; at 10% it drops to about 17. Assuming 12% and getting 10% leaves you well short with no contributions left to correct it. Use a conservative figure.

**Your FIRE number must be right first.** Coast FIRE is derived from it. If you calculated your target from today's expenses without inflating them, your Coast number inherits the same error and understates by the same multiple.

**You genuinely must leave it alone.** Coasting means not touching the corpus. Withdrawing for a car, a wedding or a house deposit resets the maths, and the loss is not the amount withdrawn but everything it would have compounded into.

**Sequence still matters.** A crash early in a coasting period, with no contributions arriving to buy the dip, hurts more than the same crash while you are still investing.

## Coast FIRE with Indian lock-ins

There is an unexpected upside here. The [EPF](/tools/epf-calculator) and NPS lock-ins that make conventional FIRE awkward in India are almost ideal for Coast FIRE.

Both are inaccessible before retirement, which is exactly the behaviour a coasting corpus requires -- you cannot raid it, and the money compounds untouched at 8.25% tax-free in EPF's case. For someone coasting to 60 rather than retiring at 45, EPF stops being an obstacle and becomes the mechanism.

The practical implication: if you are coasting to a conventional retirement age, count EPF and NPS fully. If you plan to stop working well before 60, you still need an accessible bridge, and the [FIRE guide](/fire) covers how to size it.

## Barista FIRE, briefly

A close relative worth knowing. Barista FIRE describes having enough invested that a modest income -- part-time work, freelancing, a low-stress job -- covers your remaining living costs while the corpus continues growing untouched.

The difference is what the small income is for. Coast FIRE assumes you keep earning enough to cover all living expenses. Barista FIRE assumes you draw a little from the corpus, or live on less, and top it up with light work. Both drop the requirement to save aggressively; both arrive years before full FIRE.

## How to use it

Calculate your Coast FIRE number and compare it against what you already have invested. If you are past it, you have more freedom than you realised and should probably be making different decisions about work. If you are not, it is a far nearer and more motivating target than full FIRE -- and unlike full FIRE, crossing it does not require you to change anything about how you live.

Start with the [retirement planner](/tools/retirement-planner), which reports it alongside the Lean, regular and Fat FIRE milestones so you can see the whole ladder at once.
