About AON Dividend Returns

Aon plc (AON) is a dividend-paying stock. When dividends are reinvested through a DRIP (Dividend Reinvestment Plan), they purchase additional shares, which then generate their own dividends—creating a compounding effect that can significantly boost long-term returns.

How We Calculate Total Return

Our total return calculator simulates dividend reinvestment (DRIP) by assuming each dividend payment is used to purchase additional shares at the closing price on the ex-dividend date. This methodology provides an accurate representation of how a dividend reinvestment plan would perform.
