Incomes - especially when it comes to the nobility - are complicated, I'm afraid.
The nobility are mostly landholders, and they don't have an "income" as we tend to think of it today. Take a "typical" Chelembian clanhead:
- He and his clansfolk live partly on the nalârd, partly at their city lârhus and perhaps partly travelling arouns several kantehusen. The clan income consists of what they grow on the nalârd, profits of trade and crafting done in the lârhusen.
- All that income is not the valhakar's; it's the clan's. Those who work the clan lands and craft for the clan franchises are paid, either in kind (i.e. they live in the clanhouses, eating what the clan grows and clothed in what the clan weaves) or maybe in cash.
- Whatever is left 'belongs' to the valhakar, although even this is a bit misleading, since it really 'belongs' to the clan - the valhakar just has the ultimate say about how any of the clan's goods and money are used.
So, it's really very, very variable. It varies with the clan's holdings, the quality of the harvest, the luck they have in trade and the number of "productive" clan members they have.
Even the upkeep costs are not usually spent in cash. Take a manor knight on Hârn. I estimate that his upkeep - without warhorse (which is extra) - to be around 2,700d per year. But that's not generally cash: it's food, cloth or clothing, fuel, lighting and housing for himself, a squire, 3 or so servants, feed and equipment for 3 horses (a hunter and 2 riding horses) and purchase and upkeep of his weapons, armour and so on. A lot of this might well come from his own estates - wool to weave, corn to make bread and ale, milk for the dairy, venison from the hunt, firewood from the woods, and so on. Other bits would probably be bought - armour and weapons, the finest clothing or cloth, luxury food for a feast and so on.
Oh, and his warhorse could cost an extra 600-900d per year to feed, keep and equip on top of that (grain, fruit and hay, firewood in deep winter and a groom, plus tack and caparisons, blankets, nets, troughs, buckets and so on).
Does that give you some outline idea?
