What Is a Weighted Return ?
Understanding Weighted Returns
A weighted return calculates the true overall performance of a portfolio by weighting each asset's return by the dollar amount invested. This reflects how much each position actually contributed to your total gains or losses.
Why Simple Average Return Misleads
If Asset A returns 50% on $1,000 and Asset B returns -10% on $99,000, the simple average is 20% — but you actually lost $9,400. The weighted return shows -9.4%, the truth.

Weighted Return Formula
The Weighted Return Formula Explained
The weighted return formula: multiply each value by its weight, sum those products, then divide by the total of all weights.

Values
Weights
Step 1: List values and weights
Enter each value alongside its weight. For example: Stocks 12 (weight 50000), Bonds 5 (weight 30000), REITs 8 (weight 20000).
Step 2: Multiply each value by its weight
12 × 50000 = 600000, 5 × 30000 = 150000, 8 × 20000 = 160000.
Step 3: Sum all the products
600000 + 150000 + 160000 = 910000.
Step 4: Sum all the weights
50000 + 30000 + 20000 = 100000.
Step 5: Divide to get the result
910000 ÷ 100000 = 9.10.
Common Weighted Return Mistakes
Using simple average when weights differ
When values have unequal importance, simple averaging misleads. This calculator weights correctly.
Dividing by count instead of total weight
Always divide by the sum of weights, not the number of values.
Swapping values and weights
Putting values in the weight column produces wrong results. The labeled columns prevent this.
Correct approach
Multiply each value by its weight. Sum products. Sum weights. Divide. The calculator automates this.
Weighted Return Examples
Weighted Return Example 1
Use the weighted return calculator to compute weighted results. Edit values below.
The weighted result accounts for different weights across categories, giving a more accurate composite than a simple average.
Weighted Return Example 2

The weighted result reflects the true composite value when different sources have different levels of importance or volume.
Where Weighted Return Is Used
Equity Portfolio
Compute your overall stock portfolio return by weighting each position's gain/loss by its dollar allocation.
401(k) & Retirement
See how your retirement fund allocation across stocks, bonds, and money market produces a blended annual return.
Mutual Fund Mix
Evaluate your multi-fund investment strategy by weighting each fund's performance by the capital you've committed.
Crypto Portfolio
Track overall crypto performance across holdings with vastly different position sizes and volatile returns.
Important Weighted Return Notes
Weights must be positive. The calculator requires positive weights. A weight of zero excludes that value entirely.
Equal weights = simple average. If every value has the same weight, the weighted result equals the simple average.
Result always falls between min and max values. No matter the weight distribution, the result will always be between the smallest and largest values.
Larger weights dominate the result. The larger a weight relative to the total, the more the result is pulled toward that value.
