https://www.historicalstatistics.org/Currencyconverter.html says in 1843 apparently 1 shilling was about 24 cents (1 pound=$4.79 and 20 shillings=1 pound so divided by 20 to get it), so 24*15 is $3.60. Adjusted for inflation using https://www.mortgagecalculator.org/calcs/inflation.php for 1843 to 2022, then https://www.usinflationcalculator.com/ for 2022 to 2025, and I end with 155.69 a week, or $8095.88 a year or $3.89/hr assuming a 40hr work week.

EDIT: Brain went and did 52 months not weeks.... wild.... sorry, fixed it.

Edit 2: Just a note my calculations are only directly based off consumer price index based inflation, which does not take a lot of things into account. There are other ways to value inflation, which they could have been using.

First off, $27,574 is $13.25 per hour, assuming the standard salary 40 hour weeks or $15.15 assuming hourly employee's standard 35 hour work week. This got me thinking: if kingreggieisreal got simple division wrong, what else did they get wrong...

Keeping in mind that conversion rate records from the time are lacking, from what we can surmise, in 1843 (when this story took place), a week's 15 shillings (£0.75) was worth about £110.90 today ($147.84 US). This would be about £5,766.8 per year ($7,688.76 US), or £2.77 per hour ($3.70 US) assuming 40-hour weeks, or £3.17 per hour ($4.22 US) assuming 35-hour weeks.

I'm not really sure what maths kingreggieisreal is using, but it seems flawed.

Regardless of how accurate that calculation is, keep in mind that this was not a typical minimum wage job. Kratchitt was in a office management/department head position. His subordinates git way less, most likely.

Actually, the math you’re quoting is a bit misleading. Cratchit did earn 15 shillings a week, but converting that to modern U.S. dollars isn’t straightforward. Simple inflation calculations like “$530/week → $13.50/hr” ignore things like typical work hours in Victorian England (often far longer than 40/week) and changes in living standards. Some estimates put his pay closer to $21/hr if you assume a 40‑hour week, but realistically, accounting for actual hours worked, his effective hourly rate might be much lower. So comparing it directly to modern minimum wage isn’t really accurate.

[off topic?]

I've yet to see an 'adjusted for inflation' that coincides with the actual costs of the different eras.

In 1960, $1 million would get you a Beverly Hills mansion, a fleet of cars, a Manhattan townhouse, and you'd have enough left over to live lavishly off the interest.

In 2025, $12 million will get you a fairly nice house.
