"Common" Magic Items for sale - Side Topic on cost

[koralas]

Arduin, to not bog your thread down in a side discussion on the basis for setting the prices of the items, I thought it best to open a new discussion.

Again, you failed to read the intro post. The folding boat would cost ~$42,500,000 in the currency value I'm using. The boat I listed costs about $20,000 in today’s money.

No, you just failed to describe how you arrive at your calculations. You state X made the C&C equivalent of Y, but not how you arrive at the result.

First; setting a framework for understanding price. In late medieval period the annual wage for a person like a Master Mason was about 190 C&C S.P.s per year. That is a tad less than 20 g.p. a year for a middle class wage earner.

This would be an arbitrary statement without a basis to work from on your theory. Also included should be the cost of goods using your calculations to compare against the C&C prices.

Consider that each day a Master Carpenter in 1300 made about 5 pence, in 1375 the Master Carpenter and Mason made only about 4 pence, and in 1450 it was about 6 pence. So doing simple math, we will set the wage at 5 pence/day and multiply by the number of working days. Of course that is dependent on number of working days, lets say it is as high as 300, that is 1500 pence/year. This results in 1SP = 8d using your estimate of 190SP for the Mason's annual wage.

As a comparison, the CKG sets a Craftsman/Guild Members wages at 3GP/month, 36GP/yr, or 360SP/yr.

If you are using a different basis for the wage, then fine, but how did you arrive at that number?

Then consider the cost of goods, lets take a Draft Horse, that is the equivalent of a Heavy Horse, and they cost roughly 150-240d in the 1400's, we will use the high end of that for our calculation. A Heavy Horse in C&C costs 200GP. Using the calculation above, 240d comes out to 30SP, or 3GP. Also consider that a "wealthy peasant's" wedding feast was also about 240d, while C&C doesn't have a strict number for this, lets say it is the equivalent of a good tavern meal at 1GP, and if there are 30 attenders that would be 30GP as opposed to 3GP. Mail Armor was 100s, or 1200d, that is 150SP, 15GP, compared to 150GP for a Mail Hauberk in C&C.

Don't get me wrong I like the topic, but if we are not using C&C as the basis for the cost of goods, we need to understand what that basis is.
