"Home Alone" fans are reminiscing about lower grocery bills after a TikTok video pointed out how much Kevin McCallister spent on his solo shopping trip in 1990 versus what it would cost today.

The film follows the antics of the young boy, played by Macaulay Culkin, as he is accidentally left behind by his parents who jet off to Paris for Christmas.

As the fictional 8-year old is left to fend for himself, he makes a trip to the local grocery store to pick up some food, toiletries and household necessities.

His bill comes out to about $20. One TikToker estimated that Culkin would spend close to $70 on the same grocery haul if the goods were purchased this year from Target, an increase of 250%.

How has inflation changed since 1990?

Inflation is a generalized rise in prices. It can occur across the board in an economy, or it could affect individual products or services, such as gas, rent and groceries.

$1 in 1990 has the same purchasing power as $2.30 today. Over the past 33 years, this is a change of $1.30. According to the Bureau of Labor Statistics' inflation calculator, $19.83 in December 1990 has the same buying power as $45.62 in October of 2023 − the most recent CPI data available for this year.

From 2021 to 2022, U.S. retail food prices rose by 11% − the largest annual increase in over 40 years, according to the Government Accountability Office. While average inflation was increasing in 1990 at 5.4%, it was not nearly as high as 8% last year.
