In short: The ex-dividend date is the first day a stock trades without the right to its next dividend. If you buy on or after the ex-dividend date, the seller receives that dividend. If you buy before it, you do.
The four dividend dates
- Declaration date: the company's board announces the dividend amount, record date, and payment date.
- Ex-dividend date: the cutoff for buyers. Purchases made on or after this date don't receive the upcoming dividend.
- Record date: the date you must be on the company's books as a shareholder to receive the dividend.
- Payment date: the date the dividend is actually paid to eligible shareholders.
How the ex-dividend date is set
According to the SEC's Investor.gov, the ex-dividend date for stocks is usually set on the record date, or one business day before it if the record date is not a business day. This reflects the current one-business-day settlement cycle for most stock trades.
There is an exception for very large dividends. When a dividend equals 25% or more of the stock's value, special rules apply and the ex-dividend date is set differently.
What happens to the share price
On the ex-dividend date, the share price often falls by roughly the amount of the dividend, because new buyers no longer receive it. Other market forces affect the price on any given day, so the drop is rarely exact.
This is why buying just before the ex-date to "capture" a dividend doesn't produce free money. You receive the dividend, but the shares are typically worth about that much less, and the dividend may be taxable.
Ex-dividend dates and taxes
The ex-dividend date is also the reference point for the IRS holding period that determines whether a dividend is qualified. Holding a stock only briefly around the ex-date can make the dividend ordinary rather than qualified. See the dividend taxes guide for details.
Why this calculator doesn't use dates
The Dividend Calculator projects years into the future, so it models payments by frequency rather than specific dates. It assumes you own your shares throughout and are eligible for every payment.
Worked examples
Example based on Investor.gov's illustration
- A company sets a record date of Monday, March 16, 2026.
- Because the record date is a business day, the ex-dividend date is also March 16, 2026.
- To receive the dividend, you would need to buy the shares before March 16, by Friday, March 13, excluding holidays.
- If the record date had fallen on a Sunday, the ex-dividend date would move to the prior business day, Friday, March 13.
Result: Buy before the ex-dividend date to be entitled to the dividend.
Hypothetical example: the price adjustment
- A stock closes at $50.00 the day before its ex-dividend date and will pay a $0.50 dividend.
- All else being equal, it might open around $49.50 on the ex-date.
- A buyer the day before receives $0.50 but holds shares worth about $0.50 less.
Result: Total value is roughly unchanged before tax. The dividend is not a free gain.
Examples are hypothetical and use round numbers for illustration. They do not describe any real security.
Common misconceptions
- “You need to hold the stock until the payment date.” Entitlement is based on owning the shares before the ex-dividend date. You can sell on or after the ex-date and still receive the dividend on the payment date.
- “Buying right before the ex-date is a reliable way to earn extra income.” The share price typically adjusts down by about the dividend amount, and short holding periods can make the dividend non-qualified for tax purposes.
Run your own numbers with these assumptions.
Use the Dividend CalculatorFrequently asked questions
If I buy on the ex-dividend date, do I get the dividend?
No. The seller receives it. You must buy before the ex-dividend date.
If I sell on the ex-dividend date, do I still get the dividend?
Yes, for a regular cash dividend. If you owned the shares before the ex-date, you remain entitled even if you sell on or after it.
