It all depends on what you're spending your salary on.
If a large portion of your salary is used to repay a bond then below CPI increases can possibly still work out to being an increase.
If a large portion of your salary is used to purchase food and pay municipal bills then not even a 10% increase is going to work out being an increase.
So I got my lowest increase to date this month..
15%.
Then again my first increase was 30% and it was less than the 15% increase I got now.
I moved out in the beginning of the year. The company was thoughtful enough to give me a 23% increase just before I moved out.
The first 3 months after moving out were hell.. I was always broke before the 10th of the month, but I very soon learnt that shopping between Checkers, PNP, Fruit and Veg city and our local butcher could save me about R1000pm.
Groceries now cost less than R1000 per month for my gf and I. We don't do takeaways more than once a week else it gets too expensive.
Luxuries are a thing of the past. No more PC upgrades, no Console, no new TVs, no new anything... Its taken 6 months to save for a holiday when just a year ago I could bank on my December salary.
What I've learnt is: Never move out of your parents house

Pity my mom already has a tenant staying with her... no going back for me
I believe that any TVs, Radios, PC's, Gadgets, electronics, etc. should not be included in the CPI, as that drops it too much.
If it weren't for that, our CPI would probably be about 10-15%.
Life is so expensive... its a joke :\
