Calculate portfolio return from assets and weights.
Quick answer: Investment Portfolio Calculator
Weight assets by value to see actual allocation vs your target pie chart.
Example: Total $180k: $108k equities → 60%, $45k bonds → 25%, $27k cash → 15% - if target was 70/20/10, you’re equity-heavy.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
