🎲 Expected Return Calculator (Portfolio)

A portfolio's expected return is the weighted average of the expected returns of its individual holdings, with each holding's weight reflecting its share of total portfolio value. This calculator takes a list of weights and a matching list of expected returns for each asset or holding and computes the resulting portfolio-level expected return.

Understanding your expected return result

Example allocation: 60% stocks at an 8% expected return, 30% bonds at 4%, and 10% cash at 2% combine to a 6.2% portfolio expected return, shown by asset in the table below.

Bonds30%4%1.2 percentage points
Cash10%2%0.2 percentage points
  • Expected return figures for each asset class are assumptions supplied by the user, often drawn from historical averages or an investor's own capital-market projections — this calculator does not generate or validate those figures independently.
  • This calculation measures expected return only; it does not measure portfolio risk (such as standard deviation) or the diversification benefit of combining assets with different correlations, both of which are separate concepts in portfolio theory.
  • If the entered weights do not sum to 100%, the calculator normalizes them proportionally so the expected-return calculation remains valid; the reported weight sum lets you check your inputs.

What is portfolio expected return?

Expected return is a weighted average: each asset's expected return is multiplied by its share (weight) of the total portfolio, and these products are summed to produce a single expected-return figure for the portfolio as a whole. This weighted-average approach is a foundational concept in modern portfolio theory, as taught in the CFA Institute curriculum, and underlies more advanced portfolio construction techniques.

The weights represent the proportion of total portfolio value allocated to each asset or asset class and, in a fully invested portfolio, should sum to 100% (or 1, if expressed as decimals). This calculator normalizes the entered weights by their sum, so weights do not need to be entered as exact percentages of 100 for the calculation to be mathematically valid, though the weight sum is also reported for reference.

Expected return, as calculated here, is a forward-looking estimate based on the expected returns supplied for each asset — it is not a guarantee and does not itself measure risk. Two portfolios can have an identical expected return while differing substantially in volatility, which is why expected return is typically evaluated alongside a risk or variance measure.

How to use this expected return calculator

  1. Enter the portfolio weights for each holding or asset class, separated by commas, in any consistent unit (percentages or raw proportions).
  2. Enter the expected return for each holding, in the same order as the weights, separated by commas.
  3. Ensure the two lists have the same number of entries — each weight must correspond to exactly one expected return.
  4. Read the portfolio's weighted-average expected return and the sum of the entered weights, useful for checking that the allocation adds up as intended.
  5. Example: a portfolio weighted 60% stocks, 30% bonds and 10% cash, with expected returns of 8%, 4% and 2% respectively, has a portfolio expected return of 6.2%.

The formula behind portfolio expected return

E(Rₚ) = Σ [wᵢ ÷ Σw × Rᵢ], for each asset i
where wᵢ = weight of asset i, Rᵢ = expected return of asset i, Σw = sum of all entered weights

Each asset's weight is divided by the sum of all entered weights to normalize it (so the weights effectively total 100% regardless of the units entered), then multiplied by that asset's expected return. Summing these weighted contributions across all assets produces the portfolio's overall expected return.

Common mistakes

  • Entering weights and returns in a different order, which pairs the wrong expected return with the wrong asset weight.
  • Treating expected return as a guaranteed outcome rather than a forward-looking, assumption-based estimate that may not match actual realized returns.
  • Ignoring risk entirely — a higher expected return portfolio may also carry substantially higher volatility, which this calculator does not measure.
  • Using inconsistent or outdated expected-return assumptions for individual assets, since the portfolio result is only as reliable as those inputs.
  • Forgetting to include all holdings in the portfolio; omitting a significant asset class will produce an expected return that does not represent the full actual portfolio.

Pertanyaan yang sering diajukan

How is portfolio expected return calculated?

Portfolio expected return is calculated as a weighted average: each holding's expected return is multiplied by its proportional weight in the portfolio, and these weighted values are summed. This weighted-average method is the standard approach used in modern portfolio theory to estimate how a combination of assets is expected to perform.

Do the portfolio weights need to add up to exactly 100%?

This calculator normalizes the entered weights by their total, so the expected-return calculation remains mathematically valid even if the weights do not sum to exactly 100. However, for the result to reflect your actual intended allocation, the weights should represent the true proportional share of each asset in the portfolio.

Does expected return account for risk?

No. Expected return is purely a weighted average of anticipated returns and does not incorporate volatility, correlation between assets, or downside risk. Two portfolios can share an identical expected return while having very different risk profiles, which is why portfolio analysis typically pairs expected return with a separate risk measure such as standard deviation.

Where do the expected return assumptions for each asset come from?

This calculator does not generate expected-return assumptions — they are inputs the user supplies, commonly derived from historical average returns for an asset class, published capital-market assumptions from financial institutions, or an investor's own forecast. The reliability of the portfolio-level result depends entirely on the reliability of these individual inputs.

Can expected portfolio return change if I rebalance the weights?

Yes. Because expected return is a weighted average, shifting more weight toward a higher-expected-return asset increases the portfolio's expected return (holding each asset's own expected return constant), and shifting weight toward a lower-expected-return asset decreases it. This is the basic mechanism behind asset-allocation decisions in portfolio construction.
