National Australia Bank Ltd (ASX: NAB) shares finished the week on a positive note.

Shares in the S&P/ASX 200 Index (ASX: XJO) bank stock closed up 0.6% on Friday trading for $37.73 apiece.

How does that compare the share price five years ago?

Let's find out.

How have NAB shares performed?

Five years ago, the ASX 200 was in its second month of recovery following the pandemic fuelled market crash in February 2020.

By 29 May 2020, NAB shares had already rebounded around 18% from their COVID lows.

Still, on that day, you could have picked up shares in the ASX 200 bank stock for $17.81 apiece.

Meaning a $10,000 investment would have netted you 561 shares, with enough change left over for a fast food burger.

At Friday's closing price of $37.73, those same shares were worth (a rounded) $21,167. Or a gain of 116.6%.

But let's not forget the dividends!

Adding in the passive income to NAB shares

If you'd bought NAB shares five years ago, you'd have been eligible to receive the last 10 NAB dividend payouts.

(Investors will receive NAB's latest interim dividend of 85 cents per share on 2 July. The ASX 200 bank stock traded ex-dividend on 12 May.)

All told, those 10 fully franked dividends work out to $7.29 a share in passive income.

Now, if add those dividend payouts to Friday's closing price, then the accumulated value of the NAB shares you bought five years ago is now $45.02.

Meaning those 561 shares you bought for $10,000 are worth $25,256.22, for a gain of 152.6%.

What's the latest from the ASX 200 bank?

NAB shares closed the day up 1.6% after the bank released its half year results on 7 May.

Highlights for the six months to 31 March included a 1.4% year on year increase in net operating income to $10.28 billion. Cash earnings of $3.58 billion were up 1.0%

NAB shareholders were also pleased to see that the bank's net interest margin (NIM) remained stable at 1.7%, despite stiff ongoing competition in the lending sector.

NAB's CEO, Andrew Irvine, was pleased with the bank's performance in a challenging environment.

"We are managing our business well in continued challenging operating conditions," NAB CEO Andrew Irvine said on the day.

Looking to what could impact NAB shares in the year ahead, Irvine added:

We are optimistic about the underlying growth outlook for the Australian and New Zealand economies. However, escalating global trade tensions are a key source of uncertainty. Against this backdrop, we have maintained strong balance sheet settings.
