How this is calculated
Each month: new balance = previous balance × (1 + annual return ÷ 12) + monthly deposit. Contributions equal the starting amount plus all deposits; growth is the balance minus contributions.
For example, $1,000 invested at a nominal 12% annual rate for one year without deposits grows to $1,126.83 with monthly compounding. At a 0% return, adding $100 each month instead produces $2,200.
Inflation-adjusted value = final balance ÷ (1 + annual inflation)years. Taxes, fees, return volatility, and changing contributions are excluded.

Common questions
›When are deposits added?
At the end of each month, after that month's growth or loss. The first deposit therefore receives one month less growth than the starting balance.
›Is this rate the same as APY?
No. The entered rate is a nominal annual return divided by 12. APY includes compounding. This model assumes a constant rate and does not forecast actual investment performance.
›What does today's purchasing power mean?
It discounts the projected final balance by the annual inflation assumption over the selected horizon. It is an estimate of what that future amount would buy in today's dollars.
