The cost of a scone

Postby FieryFairy on Mon Aug 23, 2010 7:11 pm

This is maybe a odd, but I am a bit bored and trying to work out if it is cheaper for me to buy scones (and then possibly muffins) from Tesco/Morrisons or to bake them. I suspect it is cheaper to buy them.

In calculating this I need to know how much, roughly, it would cost to have my electric fan oven on assuming I have it on for 5 minutes heating up, then 12 minutes baking, at 220 for scones (180 for muffins).

Does anyone, for example a physicist (they always know these sort of things) have any idea of this?

Thank you! :D

What a thing to think about - it's probably quite complicated, you'd have to think about things like the heat capacity of the scones I geuss..

It's not complicated at all and I'm no physicist.

Using the rough figures that I have...

Cost of electricity 12p/kwh
Oven rating 2.5kw
Cost per minute of running oven on full power = (12/60) * 2.5 = .5p

Even running the thing at full power for 17 minutes will only cost at most 8.5p

Divide that by number of delicious scones / muffins and add to cost of ingredients per unit.

It's probably still cheaper to make them yourself if you make a dozen or so.

I think that, for most plans, the cost of electricity units scale somewhat depending on how many you use? (And even where you live?) Not criticising, just wondering where the average came from.

Also, I have to ask - FieryFairy, are you really big on scones and trying to save money, or are you trying to win a beer bet or something?

Very helpful replies, thank you! I think you can buy value scones at Morrisons at about 28p for 8, but even then it is probably cheaper and more satisfying to make my own.

And I am afraid to say I am actually just big on scones... No beer bet to settle here!

Morrisons value will taste nowhere near as good as your own.

Last I checked the average price per kWh was 16p, hardly a massive increase though per scone.
If you do physics, panic.

My latest bill funnily enough. :P
