Coast FIRE is a specific financial independence milestone where you have accumulated enough invested capital today such that, even with zero future savings contributions, your portfolio will compound passively over time to fully support a comfortable retirement at your target retirement age.
Once you reach your coast fire calculator threshold, you no longer need to active-save another rupee. You can work a lower-stress job, take a pay cut, work part-time, or start a passion project, earning just enough to cover your current annual living costs while your existing investments compound in the background.
Our high-density coast fire calculator provides quick and precise audits. Simply input:
The coast fire calculator works by calculating your required retirement corpus in the future, and discounting it back to the present day using your nominal expected return rate.
First, your retirement expenses are adjusted for inflation up to your retirement age:
Future Annual Expenses = [ Monthly Expenses Today * 12 ] * (1 + Inflation Rate / 100) ^ Years to Retire
Second, the required retirement nest egg is determined:
Target Retirement Corpus = Future Annual Expenses * FIRE Multiplier
Finally, the required Coast FIRE Corpus Today is solved by discounting the target retirement corpus back to today at the nominal return rate:
Coast FIRE Corpus Today = Target Retirement Corpus / (1 + Expected Return / 100) ^ Years to Retire
Where:
The calculator checks the difference:
Surplus / Deficit = Current Invested Assets - Coast FIRE Corpus Today
Coasting means you stop making monthly savings contributions to your retirement accounts. Your active income only needs to cover your immediate monthly rent, groceries, utilities, and lifestyle expenses. Your nest egg is left to compound untouched.
Lean FIRE means you can retire immediately on a frugal, survival-level budget. Coast FIRE does not mean you can retire today. Rather, it means your future retirement is fully funded, but you must still cover your active day-to-day living costs until you reach your target retirement age.
