AboutNetWorthFlow
NetWorthFlow is a financial education platform built to bring government-grade accuracy to everyday personal finance decisions. All calculators are built from primary government sources and reviewed annually.
Accurate, Transparent, Privacy-First Financial Tools
We believe every American deserves access to financial calculators that reflect the actual laws, rates, and limits published by the federal government — not approximations or outdated data.
NetWorthFlow builds and maintains 17+ interactive calculators covering tax planning, retirement, Social Security, student loans, mortgages, and investment growth. Every calculation runs 100% client-side in your browser — no data is ever transmitted to any server or stored anywhere.
How We Build and Verify Our Calculators
Primary Government Sources Only
Every tax rate, contribution limit, and benefit formula is sourced exclusively from official U.S. government publications: IRS Revenue Procedures, SSA actuarial tables, HHS Federal Poverty Guidelines, and CFPB consumer guides.
Annual Review Cycle
All constants and thresholds are reviewed every January when the IRS and SSA publish their inflation-adjusted values for the new tax year. Calculators are updated before the new tax filing season begins.
Transparent Assumptions
Where calculators require simplifying assumptions (such as using current salary as a proxy for AIME, or applying a 15% LTCG rate), these are clearly disclosed in code comments, calculator disclaimers, and FAQ sections.
Conservative Estimates
When uncertainty exists in an estimate, we default to the conservative interpretation — we would rather slightly understate your expected benefit than present an overoptimistic number that leads to poor planning decisions.
Official Government Publications We Use
Tax brackets, standard deductions, contribution limits, phase-outs, and withholding tables — updated annually via Revenue Procedures.
Bend points, FICA wage bases, earnings test thresholds, claiming age adjustments, and COLA rates.
Annual Federal Poverty Level (FPL) guidelines used in Income-Driven Repayment (IDR) student loan calculations.
Mortgage amortization rules, homebuying guidelines, and consumer debt calculations.
CPI-U historical and estimated data used in inflation-adjusted salary calculations.
Survey of Consumer Finances (SCF) data used in net worth percentile benchmarks.
Educational Use Only
NetWorthFlow calculators are designed for educational and illustrative purposes only. They do not constitute tax, legal, or financial advice. Individual circumstances vary significantly, and the models presented here cannot capture the full complexity of your personal tax situation, investment history, or benefit eligibility. Always consult a licensed CPA, Enrolled Agent, or fiduciary financial advisor before making retirement planning, tax filing, or debt repayment decisions.
Data is verified annually against official IRS, SSA, and government publications. However, laws change. Always cross-reference critical figures with the relevant government agency before making financial decisions.
