Combine three asset weights and returns into an expected portfolio return.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Portfolio return to answer this question: combine three asset weights and returns into an expected portfolio return? Enter Asset 1 weight, Asset 1 expected return, Asset 2 weight, and 3 other inputs; the calculator shows Weighted expected portfolio return. Try changing one number and watch what happens to Weighted expected portfolio return. The answer tells you Weighted expected portfolio return.
Age 15Explain it to a 15-year-oldConnect it to the formula
A weighted expected return does not measure volatility, correlation, sequence risk or guarantee future performance. The rule is Portfolio return = weight 1 × return 1 + weight 2 × return 2 + weight 3 × return 3. Its input values are Asset 1 weight (%), Asset 1 expected return (%), Asset 2 weight (%), Asset 2 expected return (%), Asset 3 weight (%), Asset 3 expected return (%), and the main result is Weighted expected portfolio return. Try changing one number and watch what happens to Weighted expected portfolio return.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a personal-finance model from stated cash amounts, rates and time assumptions. The implemented relation is Portfolio return = weight 1 × return 1 + weight 2 × return 2 + weight 3 × return 3, evaluated from Asset 1 weight (%), Asset 1 expected return (%), Asset 2 weight (%), Asset 2 expected return (%), Asset 3 weight (%), Asset 3 expected return (%) to produce Weighted expected portfolio return. A weighted expected return does not measure volatility, correlation, sequence risk or guarantee future performance. The result cannot predict markets or include unentered taxes, fees, legal rules, benefits, insurance terms or personal circumstances. Verify material decisions against current documents.
What this personal finance tool does
Combine three asset weights and returns into an expected portfolio return.
Why the relationship works
A weighted expected return does not measure volatility, correlation, sequence risk or guarantee future performance.
The formula
Portfolio return = weight 1 × return 1 + weight 2 × return 2 + weight 3 × return 3
Inputs and time periods
This model uses Asset 1 weight, Asset 1 expected return, Asset 2 weight, Asset 2 expected return, Asset 3 weight, Asset 3 expected return. Keep currencies and time periods consistent, and distinguish current known amounts from assumptions about future rates.
What the result means
The primary output is Weighted expected portfolio return; supporting outputs include Highest asset expected return, Lowest asset expected return. Compare scenarios by changing one input at a time.
Limits of this compact model
This educational calculator cannot predict markets or account for every tax, fee, legal rule, benefit, insurance policy or personal circumstance. Verify material decisions with current documents and qualified advice.
