> # Coast FIRE Calculator – Find Your Coast FI Number
## What Is Coast FIRE?
Coast FIRE is a financial independence strategy that allows you to stop making retirement contributions once your investment portfolio reaches a specific target value. At that point, your investments can theoretically grow on their own until traditional retirement age.
The idea is simple:
Instead of saving aggressively forever, you save and invest heavily during your early working years. Once you reach your Coast FIRE number, you can reduce your savings rate, switch careers, work part-time, or focus on lifestyle goals while your investments continue growing in the background.
This approach has become increasingly popular among people pursuing Financial Independence and Early Retirement (FIRE).

## How Does Coast FIRE Work?
Your Coast FIRE number is the amount of money you need invested today so that, assuming a reasonable annual return, your investments will grow to meet your retirement goal without any additional contributions.
For example:
* Current Age: 30
* Retirement Age: 65
* Desired Retirement Portfolio: $1,500,000
* Expected Annual Return: 8%
Your calculator estimates how much you need invested right now to reach that future goal through compound growth alone.

## Why People Choose Coast FIRE
Many people find traditional retirement planning stressful because it requires decades of continuous saving.
Coast FIRE offers a different path.
Once your investments reach a certain threshold, your future retirement may already be funded.
This creates several benefits:
### Career Flexibility
You may be able to change careers, start a business, or pursue passion projects.
### Reduced Financial Stress
Knowing that retirement is already on track can provide peace of mind.
### Better Work-Life Balance
Many Coast FIRE followers choose lower-stress jobs after reaching their target.
### Increased Freedom
Financial flexibility allows people to make decisions based on happiness rather than income alone.

## How to Calculate Your Coast FIRE Number
Several factors influence your Coast FIRE target:
### Current Age
The younger you are, the more time your investments have to grow.
### Retirement Age
A later retirement age generally lowers your Coast FIRE requirement.
### Expected Investment Returns
Most calculations assume annual returns between 6% and 10%.
### Desired Retirement Portfolio
The larger your future retirement goal, the higher your Coast FIRE number.

## Example Calculation
Assume:
* Current Age: 28
* Retirement Age: 65
* Target Retirement Portfolio: $2,000,000
* Annual Growth Rate: 8%
Because the portfolio has 37 years to grow, the amount needed today is significantly smaller than the final target.
This illustrates the power of compound growth and long-term investing.

## Coast FIRE vs Traditional FIRE
### Traditional FIRE
Requires accumulating enough assets to retire immediately.
### Coast FIRE
Requires accumulating enough assets today to retire later without additional retirement contributions.
Traditional FIRE focuses on immediate financial independence.
Coast FIRE focuses on future financial independence.
Because of this difference, Coast FIRE targets are often much easier to reach.
---
## Coast FIRE vs Lean FIRE
Lean FIRE aims for retirement on a relatively small annual budget.
Coast FIRE does not necessarily require early retirement.
Someone pursuing Coast FIRE may continue working for decades while enjoying greater flexibility and lower financial pressure.

## Common Coast FIRE Mistakes
### Assuming Unrealistic Returns
Avoid using extremely optimistic assumptions.
### Ignoring Inflation
Inflation reduces future purchasing power.
### Not Diversifying Investments
A diversified portfolio helps manage risk.
### Delaying Investing
Time is one of the most important factors in achieving Coast FIRE.
Starting earlier can dramatically reduce the amount required.

Regular contributions build momentum.
