Individual saving means spending less on consumption than available from one's disposable income. What an individual saves can be held in many ways. It can be deposited in a bank, put into a pension fund, used to buy a business, pay down debt, or kept under the mattress, for example. The common element is the claim on assets that can be used to pay for future consumption. If there is a return on the saving in the form of interest, dividend, rent, or capital gain, there can be a net gain in individual saving, and thus in individual wealth.
