Historical dividend calculator

What historical dividend testing can reveal

A current yield is a snapshot. Historical testing adds the sequence of earlier prices and distributions. It can show whether payments remained steady, how reinvestment changed share count, how far the portfolio declined and what the position was worth at the end of the selected period.

Divvestor uses stored market history to create educational what-if scenarios. A historical result describes the past under the selected assumptions; it is not a forecast or promise.

Price history and distribution history serve different purposes

Price history shows how the market value of each share changed. Distribution history shows cash paid per share. A high-income investment can distribute substantial cash while losing market value, which is why the two histories should be reviewed together.

What a portfolio backtest should account for

• The date when each investment actually began trading.
• Cash distributions paid during the selected period.
• Stock splits and reverse splits that change share counts and per-share comparisons.
• Reinvestment purchases made at historical prices.
• Taxes, expenses and cash removed from the strategy.
• Periods of decline rather than only starting and ending values.

How to use historical results responsibly

Compare several periods and assumptions. A strategy that looks excellent during one market window may behave differently during another. Test lower distributions, less favorable prices and different reinvestment levels. The goal is not to discover a perfect portfolio—it is to understand the tradeoffs hidden by a single yield figure.
