Let’s put things in perspective now. If you are young and unmarried, and not living in Nairobi, you could be paying as little as 700 /- a month for your one-room rented apartment. If you are on the coast your home is most likely in the style of a “Swahili house,” where each room opens onto a shared courtyard, there is a shared outhouse, and if your village has electricity you may be paying a bit extra a month based on your meter-usage (add around 200 /- a month). You may spend anywhere from about 100 /- to 200 /- a day on transport, though this is a very high estimate, and you could easily pay as little as 40 /- a day. For example, I pay 30 /- each way to get from my house into Mombasa town.
If you want to go to lunch, you can get a rice and beans meal from street-side vendors for as little as 30/- in larger towns. Move up into a local-cuisine hoteli and lunch is costing around 100/- to 150/-. You may be able to afford more Western-style, “fast food,” lunch, costing anywhere from 250/- to 500/-. If you cook yourself, your dinner may cost as little as 30/-, but adding meat into the meal also gets expensive. You may go food shopping at a supermarket, but that actually doesn’t add to the cost and may be less expensive then purchasing from the local dukas (shop-stalls). However, being a bachelor, you may forgo all this and pay someone to cook and clean for you, or you may eat with a local, older family.
You have gotten this far most likely because your father was a land-owner on top of working his own trade. The stereotype is that you are of the Kikuyu tribe which comprises 30% of the population here and are notoriously good businessmen, but the fact of the matter is that modern-day successful Kenyans come from all tribes, and may even be inter-tribal, with parents hailing from different tribes. You may be the first-born of the family and thus allowed the most privileges, given the most opportunity, but also the greatest burden because there is an expectation that if your family cannot afford to help all their children equally, then those children that do succeed will help out their younger siblings.
