If you bought shares in the smallest of the big four banks, ANZ Group Holdings Ltd (ASX: ANZ) three years ago, you might have bought in at the stock's multi-year low.
The bank share plunged on the onset of the COVID-19 pandemic, reaching a low of around $15.11 in late May 2020.
At that point in time, an $8,000 investment in the stock would have seen a buyer boasting 529 shares.
Today, that parcel would be worth $12,680.13. The ANZ share price last traded at $23.97, 59% higher than its 2020 low.
For comparison, the S&P/ASX 200 Index (ASX: XJO) has risen 32% since that time.
With that in mind, no doubt investors who bought the dip in ANZ shares are happy with their investment.
And while they've been realising capital gains, they've also received some worthwhile passive income.
All dividends ANZ shares have provided since 2020
Here's a breakdown of all the dividends one who invested in ANZ shares exactly three years ago has likely received:
| ANZ dividends' pay date | Type | Dividend amount |
| December 2022 | Final | 74 cents |
| July 2022 | Interim | 72 cents |
| December 2021 | Final | 72 cents |
| July 2021 | Interim | 70 cents |
| December 2020 | Final | 35 cents |
| August 2020 | Interim | 25 cents |
| Total: | $3.48 |
As the above chart shows, each ANZ share has yielded $3.48 of dividends over the last three years.
That means our figurative $8,000 investment has offered $1,840.92 of passive income over its life.
Impressively, that leaves ANZ shares having provided a return on investment (ROI), considering both share price appreciation and dividends, of nearly 82% since May 2020.
Not to mention, all dividends provided by the bank in that time have been fully franked. Thus, they could bring additional benefits for some investors come tax time.
Those invested in the bank won't have to wait long before they receive their next dividend.
ANZ traded ex-dividend last week, with its 81-cent interim dividend set to hit accounts late next week.
Considering its upcoming interim dividend and its most recent final dividend, ANZ shares currently boast a 6.47% dividend yield.
