Coast FIRE Calculator: Single Parent
Planning for Coast FIRE as a single parent 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 $50k/year in expenses) to your realistic savings capacity ($500/month is common for this scenario). Our calculator lets you adjust these defaults to match your specific reality.
Why This Matters
Coast FIRE as a single parent is challenging but far from impossible. Childcare costs are often the biggest hurdle, but these are temporary - and expenses typically drop significantly as children become more independent. Many single parents reach Coast FIRE by focusing on incremental progress, leveraging available tax credits, and remembering that their timeline might be longer but no less valid. Your children watching you build financial discipline is also a gift that pays dividends for generations.
Key Considerations for Your Situation
Childcare costs are often the biggest hurdle, but they're temporary. Every year your children age, this expense typically decreases. Model your expenses declining over time in our calculator to see a more accurate trajectory toward Coast FIRE.
Take full advantage of tax credits and deductions available to you. Child tax credits, earned income tax credit (if eligible), and head of household filing status can add thousands to your annual savings capacity. Consult a tax professional to ensure you're capturing everything.
Focus on consistent saving rather than an aggressive percentage. Even $200-300/month invested consistently over 15-20 years can grow to a meaningful Coast FIRE number. Progress is more important than perfection.
Consider community resources and creative solutions: co-housing with other single parents, babysitting exchanges, and flexible work arrangements can reduce both costs and stress. Many single parents find the Coast FIRE community supportive and full of creative ideas.
Single Parent Financial Planning
Life insurance is non-negotiable: if something happens to you, your children need resources. Term insurance ($500k-1M) is affordable ($20-50/month) and essential.
Head of Household filing status provides better tax brackets than Single. Verify you qualify: unmarried, paid 50%+ of household costs, child lived with you 50%+ of year.
Child tax credit ($2,000/child) and dependent care FSA ($5,000/year pre-tax) provide meaningful savings. Ensure you're capturing all available benefits.
Build flexibility into your plan: childcare costs drop as kids age, then spike again (activities, cars, college). Model expenses declining then spiking, not staying flat.
Healthcare for Single Parents
CHIP (Children's Health Insurance Program) covers kids in families earning up to 200-300% FPL depending on state. Your kids may qualify even if you don't qualify for Medicaid.
ACA subsidies are more generous for families: a single parent with one child earning $50k qualifies for significant subsidies - potentially $300-500/month in premium help.
Children's coverage typically costs less to add than adult coverage. Price out "parent only" vs "parent + child" plans to find the best value.
Don't skip preventive care for yourself: as the sole parent, your health is essential. Annual checkups, dental care, and mental health support aren't luxuries.
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 Single Parent Coast FIRE
Guilt is your constant companion: saving for Coast FIRE while your kids see friends' families spending freely. Remember: financial security is a gift to your children.
Your kids are watching: the discipline, delayed gratification, and intentionality you model shapes their relationship with money for life. This is parenting.
The timeline feels endless when you're exhausted: single parenting AND saving aggressively is hard. Celebrate small wins. Progress is progress.
Self-care isn't selfish: burnout doesn't help your kids. Budget for occasional help, breaks, and sanity-preservation. You can't pour from an empty cup.

Frequently Asked Questions
Can I achieve Coast FIRE as a single parent?
Yes - Coast FIRE is achievable in any situation with the right strategy. Single Parent 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 as a single parent?
We've pre-filled $500/month based on typical single parent 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 as a single parent?
We've estimated $50k/year for single parent 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 as a single parent?
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 as a single parent are the specific tactics - which accounts to prioritize, how much emergency fund to keep, what risks you can take, and what timeline is realistic.
