A practical way to think about returns
If you want more context on setting targets and choosing return assumptions, see the savings goal questions in the FAQ.
Investment markets do not move in a straight line. Some years are strong, some are weak, and short-term declines are part of long-term investing. That is why this calculator is best used for planning ranges, not promises.
The default 7% rate is a real-return style assumption that many long-term planners use. A common framing is roughly 10% nominal growth over long periods in broad US equities, minus about 3% inflation, leaving around 7% in today's purchasing-power terms. In other words, your goal and monthly figure are interpreted in today's money.
