Coast FIRE Calculator: Divorced
Planning for Coast FIRE after divorce comes with unique considerations that generic calculators often miss. Your situation affects everything from your FI number (we've pre-filled a typical estimate of $45k/year in expenses) to your realistic savings capacity ($700/month is common for this scenario). Our calculator lets you adjust these defaults to match your specific reality.
Why This Matters
Divorce often means financial rebuilding, but Coast FIRE remains achievable. If you received retirement assets through a QDRO (Qualified Domestic Relations Order), that's a foundation to build on. Your expenses may actually be lower as a single household. Many divorcees find that the process clarifies their priorities and motivates more intentional financial behavior. Focus first on rebuilding an emergency fund (this provides psychological security), then return to aggressive retirement saving. Your timeline might be adjusted, but your goal is still valid.
Key Considerations for Your Situation
If you received retirement assets through a QDRO (Qualified Domestic Relations Order), that's your foundation to build on. These assets maintain their tax-advantaged status. Make sure you understand what you received and how it's invested.
Your expenses may actually be lower as a single household than they were married. Revisit your FI number with fresh eyes - many divorcees find they need less than they assumed because they're only planning for one person.
Focus on rebuilding your emergency fund first. Having 6+ months of expenses in cash provides psychological security during a turbulent time and ensures a temporary setback doesn't derail your long-term plans. Then return to aggressive retirement saving.
Don't let the emotional weight of "starting over" discourage you. Many people who divorce in their 30s or 40s still reach Coast FIRE within 7-10 years. Your timeline is adjusted, not eliminated.
Post-Divorce Financial Rebuilding
QDRO (Qualified Domestic Relations Order) funds retain their tax-advantaged status. Ensure these were transferred correctly and understand what accounts you received.
Social Security on ex-spouse's record: if married 10+ years, you may claim benefits on their record (doesn't reduce their benefit). This can significantly impact retirement income.
Name changes and beneficiary updates: ensure all financial accounts, insurance policies, and legal documents reflect your current status and intended beneficiaries.
Rebuilding credit: if joint accounts damaged your score, start rebuilding immediately. A secured credit card used responsibly for 6-12 months can restore good credit.
Healthcare After Divorce
COBRA continues ex-spouse's employer coverage for 36 months after divorce (not 18). This extended period is specifically for divorce situations.
ACA marketplace treats you as single for subsidy purposes. Your new, lower household income may qualify you for significant subsidies.
Document any health conditions while you have good coverage. Get copies of medical records, establish care with providers, and fill prescriptions before coverage changes.
Children can often stay on either parent's insurance. Coordinate with your ex-spouse to ensure continuous coverage and understand who's responsible for which costs.
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 Post-Divorce Coast FIRE
Starting over is demoralizing: watching your net worth split in half (or worse) after years of building is emotionally devastating. Grieve the loss, then rebuild.
Comparison to your married past is toxic: you had two incomes, shared expenses, combined assets. Your single life has different math. Compare to your future, not your past.
Spite can be motivation: "I'll show them I can thrive" is a valid reason to pursue Coast FIRE. Use whatever fuel gets you through the rebuilding phase.
New relationship finances are complicated: merging money after divorce carries extra weight. Consider keeping finances separate longer than you would have the first time.

Frequently Asked Questions
Can I achieve Coast FIRE after divorce?
Yes - Coast FIRE is achievable in any situation with the right strategy. Divorced households have unique challenges, but many people in your exact situation have reached financial independence. The path may look different (different timeline, different strategies, different FI number), but the destination is the same. Our calculator helps you plan around the specific factors that affect your situation.
What's a realistic savings rate after divorce?
We've pre-filled $700/month based on typical divorced situations, but this varies widely. Generally, aim for 15-25% of your income if possible, adjusting for your specific circumstances. Some months you may save more, some less - consistency over time matters more than hitting an exact percentage every month. Use our calculator to see how different savings rates affect your timeline.
How much should I budget for annual expenses after divorce?
We've estimated $45k/year for divorced households, which is typical for this situation. This number directly determines your FI number (Annual Expenses ÷ 0.04 = FI Number). The lower your spending, the lower your Coast FIRE target. Track your actual spending for a few months to get a realistic number - many people are surprised (in either direction) by their true expenses.
What's the best Coast FIRE strategy after divorce?
The fundamentals remain the same regardless of situation: 1) Maximize the gap between income and expenses, 2) Invest consistently in low-cost index funds, 3) Take full advantage of available tax-advantaged accounts, and 4) Stay the course through market volatility. What differs after divorce are the specific tactics - which accounts to prioritize, how much emergency fund to keep, what risks you can take, and what timeline is realistic.
