Coast FIRE Calculator for 50 Year Olds
At 50, Coast FIRE is absolutely still achievable with the right strategy and realistic expectations. While you have less time for compound growth than younger savers, you likely have advantages they don't: higher income, lower expenses (perhaps with children grown), a clearer picture of your actual retirement needs, and more financial discipline developed over decades of experience.
Why This Matters
Here's the reality: with 15 years until traditional retirement, you'd need approximately $362k invested today to reach a $1M retirement goal through compound growth alone. If that seems high, consider that catch-up contributions, Social Security optimization, and potentially working a few extra years can dramatically change the equation. Use our calculator to model different scenarios and find the path that works for your situation.
Key Considerations for Your Situation
Coast FIRE at 45-50 is absolutely achievable, though it requires focused effort and realistic expectations. The good news: you may have higher income, lower expenses (kids becoming independent), and more clarity on what you actually need in retirement than younger savers.
Take full advantage of catch-up contributions if you're 50+. You can contribute an extra $7,500 to your 401k ($30,500 total) and an extra $1,000 to your IRA ($8,000 total). These catch-up provisions exist specifically to help late starters accelerate their savings.
Consider reducing your annual spending target to lower your FI number. A $10,000 reduction in annual spending reduces your FI number by $250,000 (using the 4% rule). Sometimes small lifestyle adjustments have outsized impacts on your required savings.
Evaluate whether part-time work could be part of your Coast FIRE strategy. Many people find that working 20 hours per week in a low-stress job provides both income and purpose while allowing their investments to continue growing toward full financial independence.
Late-Start Acceleration Tactics
Catch-up contributions unlock at 50: extra $7,500 to 401(k) ($30,500 total) and $1,000 to IRA ($8,000 total). This alone adds $8,500/year to tax-advantaged savings.
Social Security optimization is critical: claiming at 62 vs 70 changes your benefit by 77%. Each year you delay past 62 adds ~8% to your lifetime benefit.
Consider the "bridge strategy": work part-time from 55-62 to cover expenses while letting investments grow, then claim Social Security to supplement.
Your FI number may be lower than you think: if you'll have Social Security, pension, or paid-off house, you need less in investments than standard calculations suggest.
Healthcare Planning by Age
The 55-65 gap is expensive: expect $1,000-2,000/month for ACA coverage before Medicare eligibility. Factor this into your Coast FIRE spending.
COBRA can bridge short gaps (18 months) but costs full premium plus 2% admin fee. Budget $1,500-2,500/month for family coverage.
Medicare starts at 65, but you must enroll during your Initial Enrollment Period or face lifetime penalties. Mark your calendar 3 months before your 65th birthday.
Consider part-time work specifically for health benefits. Many employers offer coverage for 20-30 hour/week employees - a perfect "coasting" arrangement.
Healthcare costs vary significantly by state, age, and family size. Factor in premium subsidies, deductibles, and out-of-pocket maximums when planning your Coast FIRE budget.
The Psychology of Coast FIRE
Regret minimization becomes powerful motivation. Ask: "Will I regret not taking this chance?" Most people regret what they didn't do, not what they did.
The "Tail End" concept: you may have already used 90%+ of your in-person time with parents, siblings, or even your own kids. Coast FIRE can reclaim this time.
Permission to enjoy your money is harder after decades of saving. Practice spending on meaningful experiences now - it's a skill that atrophies.
"Die With Zero" philosophy: the goal isn't to die with the most money. It's to maximize life experiences while ensuring you don't run out. You may be over-saving.

Frequently Asked Questions
Can I reach Coast FIRE at 50?
Coast FIRE is possible at 50, though it requires focused strategy. With 15 years to retirement, you'll need approximately $362k saved today to coast to a $1M goal. If you're short of that, consider catch-up contributions ($7,500 extra to 401k after 50), a flexible retirement age, or part-time work as a bridge strategy. Many people find Coast FIRE achievable by combining these approaches.
How much should a 50 year old have saved for Coast FIRE?
There's no universal answer since it depends on your target retirement spending. Using the 4% rule, if you want $40,000/year in retirement (requiring about $1M), you'd need approximately $362k at age 50 to coast to that goal with 7% returns. For $60,000/year (requiring $1.5M), you'd need about $544k. Use our calculator with your specific spending expectations for a personalized target.
What's a good savings rate at 50?
At 50, maximize what you can while taking advantage of catch-up contributions ($7,500 extra to 401k, $1,000 extra to IRA after 50). Even a 15-20% savings rate combined with these additional contributions can make a significant difference. If you're behind on savings, consider whether a few extra working years might relieve pressure and allow for a more comfortable Coast FIRE transition.
What's the Coast FIRE formula for a 50 year old?
The formula is: Coast FIRE Number = FI Number ÷ (1 + return rate)^years. For a 50 year old targeting retirement at 65 with a $1M FI number and 7% returns: $1M ÷ 1.07^15 = approximately $362k needed today. If your FI number is different (based on your expected spending times 25), adjust accordingly. Our calculator does this math automatically and shows you year-by-year projections.
Your Next Steps
Run the numbers with our calculator using both your current savings and conservative return assumptions (5-6% instead of 7%).
Explore catch-up contribution options: $7,500 extra to 401k and $1,000 extra to IRA if you're 50 or older.
Consider whether delaying retirement by 2-3 years might make your Coast FIRE number more achievable.
