Our Methodology

Every calculator on Calcora uses standard financial formulas:

• Mortgage & Loan Payments: Calculated using the standard amortization formula M = P[r(1+r)^n]/[(1+r)^n−1], where P is principal, r is monthly rate, and n is total payments.
• Compound Interest: Uses the standard compound interest formula with periodic contributions, accounting for daily, monthly, or annual compounding.
• Take-Home Pay: Uses 2024–2025 federal tax brackets and approximate state income tax rates for all 50 states. Social Security (6.2%) and Medicare (1.45%) rates follow current IRS guidelines.
• Debt-to-Income: Calculates total monthly debt payments divided by gross monthly income — the same formula used by mortgage lenders.
• Home Affordability: Based on the 43% back-end DTI limit used by conventional mortgage lenders and the 28% front-end housing ratio guideline.
• Retirement: Projects savings growth using compound interest and applies the 4% safe withdrawal rate for estimated retirement income.

Results are estimates for planning purposes. For final financial decisions, consult a qualified professional and verify figures with your lender, tax advisor, or financial institution.
