CPF - How meaningful can the interest be?

I have always been an avid reader of AK71's blog.

Today he wrote about the interest that his SA account earned.

So I thought that I shall share a little bit about our CPF contributions for 2015.

Well a little bit of background. We have been working for about 13 yrs (averaged out between the Teo of us).

It was only in the last 3-4 years when our earnings have reached the point that our mandatory contribution has hit the limit of $17000 per pax. 

So based on a simple calculation, our total CPF contribution and including our employees would be $62900.
Our deductions for housing and MediShield plans was ~$15500

Therefore the net growth should be ~$46900.

However when I compare our 2014 vs 2015 year end balance. Our CPF net gain was ~$64000.

What exactly happened???

Well it's because the total interest that we earned for all our monies in CPF was ~$15500.

So I totally concurred with AK71 when he said in one of his blogpost that a lot of his SA money is from the government.

For me, I will say that the government is paying for my housing mortgages and a big chunk of my MediShield expenses.

Of course, for the earned interest to be meaningful, the CPF monies have to be of a certain size. 

Cheers!
