Mathematical Audit

How Investment Growth Is Calculated

The visualizer uses adjusted close prices from Yahoo Finance to simulate historical portfolio growth with optional DCA and dividend reinvestment.

Shares = Initial Investment ÷ Adjusted Close Price on Start Date
Monthly DCA: New Shares += Monthly Contribution ÷ Current Adjusted Close
Dividend Reinvest: New Shares += (Shares × Dividend) ÷ Adjusted Close
Portfolio Value = Total Shares × Current Adjusted Close
CAGR = (Final Value ÷ Initial Investment)^(1 ÷ Years) − 1
Total Return = (Final Value − Total Contributed) ÷ Total Contributed
Max Drawdown = Min((Value − Peak) ÷ Peak) over all time points

Adjusted close prices account for stock splits and dividend payouts, providing an accurate picture of total return. All calculations run entirely in your browser.
