This calculator gives you a clear picture of the opportunity cost of leaving your cash in a savings account instead of investing it. It completely replaces the original view's logic to tackle a brand new question, comparing standard bank interest against market returns to show how much wealth you might be leaving on the table. It's a straightforward and effective tool, though you'll want to remember that it doesn't account for taxes or inflation, which will take a bite out of your actual take-home amounts in the real world.
