Before you look for an affordable medical aid, first review you monthly budget and decide upon what you can afford. Health care is expensive but paying for your medical aid every month should not break your budget. Most medical aids will advise that you do not join a plan that will cost your more than 10% of your gross income. Remember that you will get a small tax benefit for having medical aid cover so you should factor this in as well.
If you have a large family and many dependents, then your medical aid can be costly and you may cross this 10% budget.
