What we publish

MoneyMath Hub publishes free calculators and explanatory content for personal finance — borrowing, investing, retirement, inflation, and U.S. paycheck planning. Every page is designed to show the formula behind a result, document its assumptions, and help readers compare scenarios before making a money decision.

Methodology principles

Calculators implement standard finance and payroll formulas. Inputs are processed in the browser; we do not store the numbers you enter. Where a tool depends on tax tables, withholding rules, or state-specific logic, those assumptions are surfaced on the page so the math is auditable. Results are educational estimates and should be verified against current official guidance, your lender or employer, or a qualified professional.

Sourcing standards

Tax and payroll pages link to authoritative primary sources where relevant — for example IRS Publication 15-T, the IRS Tax Withholding Estimator, the SSA Social Security wage base, and the Federation of Tax Administrators directory of state tax agencies. For finance formulas, we reference the standard textbook definitions used in time-value-of-money, mortgage amortization, and bond yield calculations.

Update approach

Pages are reviewed when formulas, source assumptions, examples, supporting explanations, or user experience need improvement. Tax-sensitive pages (paycheck, retirement, take-home pay) are revisited when withholding rules, contribution limits, or bracket structures change. Each calculator carries a visible "Updated" date so readers can see when the page was last revised.

Trust commitments

We aim for clarity, consistency, and transparent assumptions. We do not present calculator outputs as financial, investment, tax, payroll, legal, or accounting advice. Advertising or affiliate relationships, where used, do not influence calculator formulas or methodology, and any monetized recommendation should be clearly disclosed on the page where it appears.

Corrections

If you spot an error in a formula, assumption, or explanation, email hello@moneymathhub.app with the page URL and a short note. See our Contact page for what to include in a correction request.
