2. Estimates Only — Results May Vary

- Variable interest rates and market fluctuations
- Changes in tax law, rates, and regulations

- Changes in income, expenses, or life circumstances
- Insurance premiums, which vary by carrier, location, and individual risk factors
Do not make major financial decisions based solely on the results from these calculators without consulting a qualified professional.
3. Calculator Assumptions & Methodology
Each calculator relies on specific mathematical models and assumptions. Key assumptions are described below:
Coast FIRE Calculator: FI Target = Annual Spending × 25 (based on the 4% safe withdrawal rule from the Trinity Study, 1998). Coast Number = FI Target ÷ (1 + Return Rate)^Years. Assumes a constant nominal annual return. Does not account for inflation, sequence-of-returns risk, or Social Security income. The 4% rule is a guideline, not a guarantee.
Credit Card Payoff Accelerator: Interest calculated monthly as Balance × (APR ÷ 12). Simulation runs month-by-month. Assumes a fixed APR and fixed payment. Does not account for fees, penalty rates, or minimum payment changes. Actual card terms vary by issuer.
Freelance Rate Calculator: Gross revenue needed = (Salary + Costs) ÷ (1 − SE Tax Rate). Self-employment tax default is 15.3% (the combined employee/employer FICA rate). Individual income tax rates, deductions, and state taxes are not included. Consult a CPA for personalized tax calculations.
True Car Cost Calculator: Depreciation estimated at 15% per year compound — a general average for new vehicles. Actual depreciation varies significantly by make, model, mileage, and market conditions. Does not include registration fees, parking, or tolls.
Subscription Bleed Calculator: Opportunity cost uses the Future Value of Annuity formula at 7% annual return (a commonly cited inflation-adjusted historical average for diversified US equity index funds). Past market performance does not guarantee future results. Actual investment returns will vary.
Loan Calculator: Uses standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1]. Assumes a fixed interest rate for the entire loan term. Does not include origination fees, prepayment penalties, or other lender-specific charges unless reflected in the APR you enter.
