What We Do
Imagine Calculator provides free financial tools to help you visualize investment outcomes, understand the effects of compounding, and explore historical market data. 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
- DCA Calculator— Simulate dollar-cost averaging into crypto or stocks.
- Compound Interest— Project growth with compound interest and monthly contributions.

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.

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