What does the Portfolio Diversification do?
Portfolio Diversification works out the diversification score from the Stocks, Bonds, and Real Estate, following standard Finance conventions — the page defaults produce a diversification score of 59/100.
- Inputs: Stocks, Bonds, and Real Estate.
- Output: the diversification score, plus the intermediate steps behind it.
- Method: the standard Finance formula, evaluated entirely in your browser.
Quick answer
With the default inputs (stocks of 60,000, bonds of 20,000, real estate of 10,000), portfolio diversification returns a diversification score of 59/100. Assumptions and limits are summarized below.
How does the Portfolio Diversification work?
Portfolio Diversification computes the diversification score directly from your inputs — the Stocks, Bonds, and Real Estate feed the formula. Nothing is uploaded: the math runs locally in your browser and the result appears as you type.
How the Portfolio Diversification works
Portfolio Diversification turns the values you enter into a verified diversification score — the formula, every intermediate step, and the assumptions sit beside the result instead of hidden behind it.
Using the Portfolio Diversification
- Stocks — the value that feeds directly into the formula — match it to the scenario you are modeling before moving on.
- Bonds — a core input the formula applies directly — keep the units consistent with the label.
- Real Estate — one of the values the calculation builds from; the result reflects exactly what you type here.
- Check the result. The diversification score is shown as soon as the inputs are valid, and the steps beneath it show exactly how it was derived.
- Explore. Each input change recalculates instantly; watching the diversification score move tells you which factor dominates your case.
The formula behind the result
Portfolio Diversification substitutes the Stocks, Bonds, and Real Estate into the formula, evaluates it in the order shown in the steps panel, and reports the output rounded for readability.
Worked example: with stocks of 60,000, bonds of 20,000, real estate of 10,000, this portfolio diversification calculation returns Diversification Score: 59/100. The same run reports HHI: 0.415 | 60% / 20% / 10% / 5% / 5%.
The steps it follows:
- Calculate total portfolio
- Calculate weight of each asset class
- HHI = sum of squared weights
- Diversification = 1 − HHI (higher = more diversified)
Substitute your own values and the same steps produce your answer — that is the point of a calculator that shows its working.
Understanding the result
To interpret the result from portfolio diversification, read it together with the intermediate figures — the pairing is what makes the number auditable.
Where it helps
Common scenarios for Portfolio Diversification: planning ahead, comparing scenarios side by side, and double-checking the diversification score. The step list makes it equally useful for learning the method and for double-checking someone else's numbers.
Common mistakes
Mixing up inputs with similar labels is the classic portfolio diversification mistake; the steps panel is the quickest way to spot a value that landed in the wrong field.
Tip: If the diversification score looks wrong, read the steps panel before re-entering anything; it usually shows exactly where the number departed from expectation.
Assumptions and limitations
Portfolio Diversification assumes the units shown in each label — entering values in different units will skew the figure proportionally.
Why use this calculator
Because the page doubles as documentation: Portfolio Diversification puts the formula, a worked example, and the assumptions right beside the calculator.

Frequently Asked Questions
What does the Portfolio Diversification calculate?
Portfolio Diversification answers one question well — given the values you provide, what is the figure? Enter the Stocks, Bonds, and Real Estate, and the result panel returns the value with the full working underneath. Because the working is visible: Portfolio Diversification shows each operation behind the figure in the steps panel, so you can verify the result instead of trusting a black box.
How is the diversification score calculated?
The first steps are calculate total portfolio, then calculate weight of each asset class. The relationship between the inputs is fixed by the formula, and Portfolio Diversification makes each substitution explicit so nothing about the output is hidden.
What do I need to use the Portfolio Diversification?
The Stocks, Bonds, and Real Estate it asks for, or the page defaults if you just want to see the calculation work. Each input maps directly to the formula, and changing any one of them recalculates the diversification score instantly.
What does the result from the Portfolio Diversification mean?
The main number the portfolio diversification returns is the diversification score for your exact inputs, and the supporting figures and step list give it context. The model behind Portfolio Diversification covers the standard case; special cases, edge values, or jurisdiction-specific rules may need manual adjustment.
When is the Portfolio Diversification most useful?
Students, planners, and professionals use it for planning ahead, comparing scenarios side by side, and double-checking the diversification score, and for sanity-checking numbers that arrived from somewhere else.
