AT&T Inc. pays a 4.7%% trailing yield. Here is what a steady monthly plan does to that income over 20 years.
Dividend data as of August 7, 2026
Using T’s own 4.7%% trailing yield and -11.8% dividend growth, with every dividend reinvested and a modest 5% a year of share-price growth. Year 1 pays $591; year 20 pays $391, which is $32.57 a month.
T’s dividend has SHRUNK over its recorded history (-11.8% a year). The example uses that real number rather than a flattering one — a falling dividend is exactly the risk this tool exists to show.
Milestones
The month your projected dividend income first covers each bill. Change any amount to your own.
The first bill most people cover, usually years before the big ones.
Small, unavoidable, and due every single month.
The point where dividends start covering a real necessity.
The big one. In most plans this is the last to fall.
The three layers add up to the portfolio value exactly. With reinvestment off the middle layer is zero — those dividends went to your bank account instead.
Yield on cost measures the dividend against the money you actually paid, so it climbs as the dividend grows. It is a nice number to watch and a bad number to decide with — it says nothing about whether the shares are worth buying today.
Every year up to year 10, then every fifth year.

Open the calculator prefilled with T, then change the amount, the monthly contribution, the horizon and the assumptions.
The same worked example, run on the other securities in this set.
Every number after today rests on assumptions you can change, and changing them changes the answer a lot. Dividends are declared at a board’s discretion and can be reduced or stopped at any time — several of the securities on this page have done exactly that. The calculator ignores tax, fees, foreign withholding and currency moves, all of which reduce real income. Past dividend growth does not predict future dividend growth. This is educational information, not investment advice; you are responsible for your own decisions, and a regulated adviser is worth the money for the big ones.
