Our goal is to make financial concepts accessible through interactive calculators and data-driven scenarios. All tools are for educational purposes only and do not constitute financial advice.

Our Calculators

Methodology

Calculations are performed client-side using deterministic formulas. Compound interest uses A = P(1 + r/n)^(nt). CAGR uses (endValue / startValue)^(1/years) − 1. DCA sums periodic purchases at historical prices. Inflation adjustment uses CPI-U ratios from the Bureau of Labor Statistics.

Data Sources

Cryptocurrency: Live prices from CoinGecko; historical snapshots in our static dataset.

CPI: U.S. BLS CPI-U annual averages, 2000 through 2026 (2026 estimated where noted).

Benchmarks: S&P 500 and gold year-start levels for scenario comparison tables.

Data last verified: May 15, 2026 (2026-05-15)
