Answers from our legacy knowledge base, updated for the current calculator experience.
Are these calculators financial advice?
No. Fire-Calc tools are educational and scenario-based. They help you compare assumptions, but they do not replace personalized advice from licensed professionals.
FIRE basics: what is FIRE and the 4% rule?
FIRE means Financial Independence, Retire Early. A common planning shortcut is the 4% rule, where first-year withdrawals are 4% of portfolio value and later years are adjusted for inflation. This is a heuristic, not a guarantee.
Which calculators are available?
Current tools include FIRE, Advanced FIRE, Coast FIRE, Compound Interest, Retirement Goal, Budget Planner, Debt Payoff, Emergency Fund, Mortgage, Rent vs Buy, Paycheck, and Job Offer Comparison planning workflows.
- Use retirement calculators for long-horizon balance modeling.
- Use debt, budget, and paycheck tools for monthly cash-flow planning.
- Use housing tools to compare long-term ownership versus renting costs.
Homebuying questions: rent vs buy, affordability, and PMI
Buying often becomes more favorable with longer stay horizons, stable income, and sufficient reserves. Affordability guidelines often target housing costs under 28% of gross income and all debt under 36%. PMI is typically required for low down payments and can often be removed later when equity thresholds are reached.
Debt and budgeting: avalanche, snowball, and 50/30/20
Avalanche targets highest interest first to reduce total cost. Snowball targets smallest balances first for momentum. The 50/30/20 guideline allocates 50% to needs, 30% to wants, and 20% to savings/debt payoff.
Emergency fund sizing guidance
A common target is 3–6 months of essential expenses, with 6–12 months often preferred for variable income, single-income households, or higher job uncertainty.
Retirement account basics and contribution limits
401(k) plans are typically pre-tax with potential employer match; Roth IRAs are funded with after-tax dollars and can provide tax-free qualified withdrawals. Contribution limits and eligibility thresholds can change annually, so always confirm current IRS rules before acting.
What if my income is too high for direct Roth IRA contributions?
Some households evaluate a “backdoor Roth” strategy (nondeductible traditional IRA contribution followed by Roth conversion). Because tax treatment can be complex, especially with existing pre-tax IRA balances, consult a tax professional before implementation.
