Many retirees spend years carefully planning for taxes, Social Security, investment withdrawals, and healthcare costs. Yet one retirement expense often catches people completely by surprise. It is called IRMAA, which stands for Income Related Monthly Adjustment Amount. Most retirees simply know it as the Medicare surcharge. The frustrating part is that many people do not discover IRMAA until after the damage has already been done. A large Roth conversion, a substantial capital gain, the sale of a property, or a large IRA withdrawal can trigger higher Medicare premiums years later.
One of the most important concepts in investing is also one of the simplest: compound interest. Most people understand the basic idea that investing can help your money grow. What many people underestimate is how dramatically time can impact the outcome. When people think about building wealth, they often focus on finding the right investment, earning a higher return, or predicting where the market is headed next. While those things receive a lot of attention, they are often far less important than a much simpler factor: how long your money remains invested.
