In my opinion 300k net. Live off 100k and invest 200k. That's 2.4 million per year for investments which is pretty decent. 100k is enough to live on and drive etc in Nairobi assuming you are single or have only one kid and a working spouse.

And the rent would be how much?

Deduct school fees and utilities from that. You'll be left with next to nothing if anything at all

You probably earn more, that's why. Comfortable is relative and you may already be used to luxuries not available to the common man. A single man will live very comfortably in Nairobi spending 100k per month on all expenses. The OP asked for a comfortable life, not luxurious life. 30k will get you a decent two bedroom apartment within a 20 km radius from CBD with secure parking. 70k is enough to maintain a basic 1500cc Premio, drink every Friday+nyama choma etc. 100k is a lot of money to spend for a bachelor or a man with a low maintenance employed girlfriend. However, I agree that the budget may exceed 100k if a kid comes into the picture because there will be need for at least 3 bedrooms (50k stand alone house in a gated estate), and normal expenses that come along with kids e.g live-n househelp, medical check-ups etc. So, 100k expenses may be a very tough call to live comfortably when raising a child. Say 150k if there is a kid. So, spend 150k and save/invest 150k.

90% of salary earning employees earn less than 100k married or otherwise.the trick is to adjust as the fortunes change.try to live within means and take that as the comfortable life in that season.some start down there but through hardwork and honesty later live a relatively comfortable life in a third world country standards

50K rent is not considered decent. It's considered rich. Decent ni kitu 15-30(single/small family)

If you don't believe, check all these popular places where your comfortable working class & biz people live- Ruaka, Thindigua etc

Kilimani isn't for kila mtu

Again it depends on your type of school for your kidos and how much peer pressure you can withstand from akina johnies.

Talk of salaries is talk about employment in the formal sector, which accounts for very limited numbers in Kenya.

Normally in Kenya, most people do wages and side hustles that tend to have multiplier effects. For example you can guess how the police constable ended up having a Toyota packed outside the post.

Anyway, @2012's question doesn't appear to have an answer since worry has very little to do with wage or salary but has much to do with ambition and desire. Moreover, even if one had 2.4M per year for investment there'd still be worries about how exactly to invest the money especially when the time needed to run any venture is limited because one is busy earning the salary.

Worry in an urban set up is a function of how capital works and normally, the greater the capital the greater the worry.

Notice how so far guys are talking about consumption. But consumption has no end.

BTW, I'd be interested to know how many wazuans have gold as part of their possession and why they have it in the first place...

Living without worries is relative. If you are well off, you can go and rent those 200k plus per month houses in exclusive gated estates in Rosslyn or other areas of Spring Valley but be prepared to live with rich Indians, I think that lifestyle requires 1 million plus per month. If you have some property generating that in rent, you can rest easy among the super elite without worries. If that 1 million monthly cashflow is from business, you can live there but with worries because businesses don't have stable income.

I'd say that some like @Hamburglar work for Trump inc.
