## Quick Answer

Determine your Coast FIRE number. Enter your current assets, planned retirement spending, withdrawal rate, expected return, and the number of years remaining, to see whether your existing savings can reach the target on growth alone.

## Definition

A Coast FIRE calculator is a financial planning utility that calculates the target savings balance needed to retire comfortably at a chosen age without adding further retirement contributions. Coast FIRE is achieved when current savings, compounded over the remaining years to retirement without new deposits, grow to satisfy the target nest egg. The calculator works in years remaining rather than ages: enter current assets, annual retirement spending, a safe withdrawal rate, an expected return, and how many years are left before retirement. Age fields are not part of it. Financial independence advocates use this tool to determine when they can shift to lower-stress careers.

## How to Use

1. **Enter the years remaining** — Enter how many years are left until you plan to retire. The calculation depends only on that gap.
2. **Input financial balances** — Enter your current retirement savings balance and expected annual expenses in retirement.
3. **Read Coast FIRE results** — View your Coast FIRE number, how far your current assets are from it, and the single balance those assets are projected to reach with no further contributions.
