Investment Return Calculator
Compound growth is the single most useful concept in long-term investing — and the easiest to mis-estimate by eye. This calculator projects the future value of recurring contributions, both before and after a chosen inflation assumption.
The investment-return calculator answers the question “if I save $X per year at Y% over Z years, what will I have?” — and crucially, it answers it in both nominal and real (after-inflation) dollars. Mortgage-amortisation logic for debt-side compounding is on the Loan & Mortgage Calculator.
Preview — the interface is shown here for reference. The calculation engine is in development. Standard compound-growth formulas mean this is among the easiest of our preview shells to activate; expect it in an early update.
