Ever wondered how much you need to invest today so your retirement nest egg grows on its own? The Coast FIRE Calculator helps you answer that question. “Coast FIRE” is a strategy within the FIRE (Financial Independence, Retire Early) movement that involves saving and investing enough early in life that, without further contributions, your portfolio will grow to fund retirement. Once you reach your Coast FIRE number, you can shift to work that covers only your current expenses while compound interest does the heavy lifting. Key Features: * Easy inputs: Enter your current age, target retirement age, desired retirement income, inflation assumptions and your preferred safe withdrawal rate. * Automatic Coast FIRE calculation: Instantly see your Coast FIRE number and the age at which you’ll hit it, based on your assumptions. * Scenario comparison: View default and slower‑growth scenarios to understand how varying investment returns change your path. * Year‑by‑year projections: Get a detailed table showing annual growth and portfolio balances from now until retirement. * Progress tracking: See your current progress toward your Coast FIRE number, both in today’s dollars and at retirement. * Save & manage calculations: Save multiple scenarios (e.g. “Coast at 30,” “Coast at 38,” “Coast at 40”) and revisit them later to track your progress. * Flexible retirement planning: Explore different retirement ages and income targets. Understand how changes in inflation, investment growth and withdrawal rates affect your nest egg. Coasting to financial freedom doesn’t mean quitting work entirely; it means knowing your future is secure so you can enjoy life on your own terms. Download the Coast FIRE Calculator to demystify your retirement goals and see if you’re on track for financial independence.
