By allowing you to invest in more shares than you could typically afford, you have the chance to gain higher returns when your portfolio rises in value. However, this also puts you at risk of bigger losses if the value of your portfolio drops.
Margin lenders will only lend a percentage of the total investment amount. This percentage is known as the loan to value ratio (LVR). So if a margin loan's LVR is 65%, if you plan to borrow to buy $10,000 worth of shares, you would need to pay $3500, or 35% as a deposit.
