Two numbers, two meanings
The first figure is the balance your account statement would actually show at that age. The second is the same balance shrunk back to today's prices using the inflation rate, which is the number to compare against your current cost of living. Someone with $50,000 saved, adding $700 a month at 7% from 35 to 65, would see about $1.26 million on the statement, but that would feel more like $520,000 does today at 3% inflation.
The last row turns the result into a rough income using the 4% rule, which is often the most useful way to judge whether a balance is enough.
Making the projection realistic
Projections like this assume a smooth return every year, while real markets jump around. Many people also shift toward bonds as they get older, which lowers the expected return in the last decade. If you plan to do that, try a return one point lower for a more conservative estimate.
Common questions
How much will I have if I save $500 a month for 30 years?
At 7% you would have about $610,000, or roughly $250,000 in today's money at 3% inflation.
Why does inflation matter so much?
Over 30 years, 3% inflation cuts buying power by more than half, so a projection in future dollars can look much bigger than it feels.
Should I include Social Security or a pension?
This calculator covers savings only. Add pension income separately when judging whether you have enough.
