How to measure your real net worth after inflation
A 5% rise in net worth looks good. But if prices rose 3% over the same year, part of that gain only kept up with the cost of living. A real net worth calculation makes the difference visible.
Nominal versus real change
The nominal change is how much your net worth grew in dollars. The real change removes inflation from that growth and shows whether your purchasing power actually increased.
Work through an example
Say your net worth was $100,000 at the start of the year. With 3% annual inflation, you need $103,000 at year-end to keep the same purchasing power. If your net worth is $108,000 at year-end, the nominal gain is 8%. The real result is $108,000 ÷ $103,000 − 1 ≈ +4.9%. Your purchasing power grew by about 4.9%, not 8%.
Separate savings added during the year
Money you save from your income during the year also raises net worth, even if your assets did not grow in value. For a fair comparison, add those savings to the required amount, grown by inflation from the date they were added. That keeps "I saved money" separate from "my assets beat inflation".
Which inflation rate to use
The official consumer price index is a common starting point. If your spending differs from the average basket, you can use a personal rate instead. What matters is using the same method every year; if you change it, years are no longer comparable.
