Here's how you can optimise the 1% extra interest...
1.	Leave your CPF savings in your accounts to earn the extra interest
	The first $60,000 of your combined CPF balances, with up to $20,000 from your Ordinary Account (OA), will earn an extra 1% interest. So, leave your money in your CPF accounts to enjoy this extra interest. Click here to calculate your extra interest.
2.	Transfer savings from your Ordinary Account (OA) to the Special Account (SA)
	Transfer the savings from your OA to your SA for higher interest if you do not intend to use your OA for housing. You can transfer an amount up to the prevailing Minimum Sum (MS) of $117,000* in your SA. *Effective from 1 July 2009.
