What is Coast FIRE?
Coast FIRE (also searched as coast fi or coastfire) is the milestone where your current savings will grow to your full FI number by retirement age through compound interest alone, without any additional contributions. Once you hit your coast fire number, you only need to earn enough to cover current living expenses, not save anything extra.
This coast fire calculator is built for digital nomads and remote workers who want to switch to lower-income work, take sabbaticals, or work part-time. Unlike single-estimate US calculators, we factor in real cost of living data across 11,400+ cities, so you can see exactly how far your coast fire number stretches in Lisbon, Chiang Mai, or Mexico City.
How the Coast FIRE Number is Calculated
Coast FIRE Number = FI Target ÷ (1 + real return rate)^years to retirement. It's the present value of your FI target, discounted by expected returns over time remaining until retirement.
Example: If your FI target is 1,000,000 EUR, you want to retire in 30 years, and expect 7% real returns, your Coast FIRE number is about 131,000 EUR today.
Coast FIRE Tips for Digital Nomads
- 1. Front-load savings in your 20s-30s: The earlier you hit your Coast FIRE number, the more years compound interest works for you. Aggressive saving early lets you switch to lower-stress remote work once you coast.
- 2. Use geo-arbitrage to minimize expenses while coasting: Once you hit Coast FIRE, you only need to cover current living costs. Living in Chiang Mai, Lisbon, or Medellín means you need far less income than in London or New York.
- 3. Consider Barista FIRE as a complement: Part-time remote work covers expenses while your investments grow untouched. Pair Coast FIRE savings with part-time freelancing for a comfortable coasting phase.
- 4. Track your Coast FIRE progress annually: Market returns may let you coast earlier than expected. Recalculate yearly, a strong bull market could move your coast fire number forward by several years.

Frequently Asked Questions
What is Coast FIRE?
Coast FIRE is the point where your current savings, left to grow through compound interest, will reach your full FI number by a target retirement age, no additional savings required. Once you hit Coast FIRE, you only need to earn enough to cover current living expenses.
How do I calculate my Coast FIRE number?
Coast FIRE Number = FI Target / (1 + real return rate)^years to retirement. It's the present value of your FI target, discounted by your expected real investment return over the years remaining until your target retirement age. Plug in your numbers above and the calculator does the discounting for you.
What is the difference between Coast FIRE and regular FIRE?
Regular FIRE requires enough invested to cover all expenses from investments today. Coast FIRE means you've saved enough that compound growth alone will get you to FI by retirement, you only need to cover current expenses with work income.
Can I still work after reaching Coast FIRE?
Yes. Coast FIRE means work is optional for savings purposes, you can work a lower-stress job, freelance, or pursue passion projects. You just need to cover current living expenses while your investments compound.
How does Coast FIRE work for digital nomads?
Digital nomads can leverage geo-arbitrage to reduce current expenses, making it easier to cover living costs after reaching Coast FIRE while their investments compound. Living in lower-cost countries means you need less income from work while coasting.
Coast FIRE vs Barista FIRE: what's the difference?
Coast FIRE means your investments alone will compound to your full FI number, so you only need earned income to cover today's living costs, at any job. Barista FIRE goes a step further: the part-time work itself is part of the plan, often chosen specifically for health insurance or extra savings. Many nomads treat Coast FIRE as the milestone and Barista FIRE as one way to live once they've hit it.
What return assumption should I use for Coast FIRE?
Most Coast FIRE calculators, including this one, default to a 7% real return (after inflation), based on long-run stock market averages. If you hold a more conservative portfolio or want a safety margin, try 5% instead, it raises your coast fire number and gives you a more cautious estimate. The lower your assumed return, the more you need saved today to reach the same FI target.
