Sounds about right, we used to get angry messages from head office if we went above 20c per litre back in the early 90's, adjusting for inflation that comes out to about 40c now. Adjust again for more malt and higher hop loads and your figure would be close.
Hops have also gone up in price spectacularly, Czech Saaz was the most expensive hop around at the time at all of $9 per kilo ($17 / kg in 2016 money)
Personally I come in average about $1 a litre. If something low(er) ABV than my median 5.5%, reuse yeast, malt driven over hop drive, I'm as low as 40c a litre, but I don't brew these too often...
A fermenting batch of honey wheat, 50L batch (~45L packed, after losses) low on the ingredients at $28 grain, $2 hops, $7 honey, $2 yeast starter (reused yeast w/extract starter) putting me at about $40.
I use about $2 of gas, $2 electricity per brew (******* South Australia) as a conservatively high number, my fermentation fridge costs about $1 a month (measured with a killawatt)... oh look ~$45 for 45 litres for a ~5.5% beer
this beer would have been OK without the honey too, about 4.5% but cheaper.
Naturally there's other minor things which to the home brewer are incidental and not considered such as priming sugars, caps (2c each for me)
Now in a hoppier beer of similar gravity I would have a slightly higher grain cost but higher hop cost, probably come in around $1.20 a litre.
I just make sure I buy my hops in bulk at good prices, grains I get for a good price, yeast I'll reuse if it's suitable else
Works for me
