What is DRIP investing?
DRIP stands for Dividend Reinvestment Plan. Instead of taking a cash dividend out of the account, the dividend is used to acquire additional shares of the same stock or ETF. Those new shares can then produce future dividends, which is the basic engine behind the income snowball.
In Canada, many investors encounter broker-run synthetic DRIPs. The important detail is that whole-share DRIP usually needs the dividend payment to cover at least one full share at the current price. If the payment is short, the cash can remain uninvested until the next cycle or manual planning step.
The useful question is not whether DRIP sounds attractive in the abstract. It is whether the position has enough income, payment frequency, and buffer to keep reinvestment working under realistic price and dividend assumptions.
Core Metric
The DRIP Buffer explained
The DRIP Buffer is the cushion between the dividend cash generated in one payment cycle and the cost of one additional share. If a quarterly dividend payment is $120 and the share price is $100, the buffer is $20. If the share price is $130, the DRIP is below the whole-share threshold.
That threshold is also the DRIP Break Point: the share price where one dividend cycle no longer covers one new share. The Coverage Ratio turns the same idea into a simple multiple.
Buffer is useful because it keeps the DRIP conversation grounded in math. A position can have a dividend, a familiar ticker, and a long history, while still sitting close to the point where whole-share reinvestment stops.
Risk Lens
Price Creep - the silent DRIP killer
Price Creep is what happens when a share price rises faster than the dividend payment supporting the DRIP. The portfolio value may look stronger, but the reinvestment threshold can quietly move farther away.
Example: a position generates $95 per quarter and the share price moves from $88 to $102. The dividend did not disappear, but the whole-share DRIP may stop because the next share now costs more than the payment cycle produces.
Prospyr treats price creep as a planning framework and app concept: a way to understand when reinvestment math is getting tighter. On this public page, the safest next step is to model the same pressure inside the DRIP Engine Simulator.
