Portfolio Return Calculator

Estimate your portfolio’s weighted average return

Weighted Portfolio Return:

⚠️ Ensure weights add up to 100% for accurate results.

Investing is not just about buying assets—it’s about knowing how well they perform over time. If you own stocks, bonds, mutual funds, ETFs, or real estate, it can be difficult to track performance when different assets grow at different rates.

This is where a Portfolio Return Calculator comes in. It helps investors calculate:

Total return – overall percentage gain or loss.
Annualized return – average yearly return.
Weighted return – return adjusted for portfolio allocation.

By using this calculator, you can easily measure how your portfolio is performing, compare it against benchmarks, and make informed financial decisions.

Key Inputs:

Initial Investment – How much you invested at the start.
Ending Value – Portfolio’s final value (including dividends/reinvestments).
Investment Period – Length of time you held the investments.
Contributions or Withdrawals – Additional deposits or withdrawals during the period.
Asset Allocation & Individual Returns – Used for weighted average calculations.

Key Outputs:

Step-by-Step Guide: Using the Portfolio Return Calculator

Step 1: Enter Initial Investment

Example: $50,000 at the beginning of the year.

Step 2: Enter Ending Value

Example: $62,000 after one year.

Step 3: Enter Additional Contributions/Withdrawals

Example: $5,000 contributed mid-year.

Step 4: Enter Time Period

Example: 1 year.

Step 5: Enter Individual Asset Allocation (Optional)

Example:

50% Stocks – 12% return.
30% Bonds – 4% return.
20% Real Estate – 8% return.

Step 6: Click “Calculate”

The calculator instantly shows your portfolio’s total, annualized, and weighted returns.

Example Calculation

Let’s say you invested in three assets:

Stocks: $25,000 with a 10% return.
Bonds: $15,000 with a 4% return.
Real Estate Fund: $10,000 with a 6% return.

Step 1: Weighted Returns

Stocks: 25,000 ÷ 50,000 = 50% allocation × 10% return = 5%.
Bonds: 15,000 ÷ 50,000 = 30% allocation × 4% return = 1.2%.
Real Estate: 10,000 ÷ 50,000 = 20% allocation × 6% return = 1.2%.

Step 2: Portfolio Weighted Average Return

= 5% + 1.2% + 1.2% = 7.4%.

Step 3: Portfolio Growth

= $50,000 × (1 + 0.074) = $53,700.

👉 Your portfolio gained $3,700 in one year, with a 7.4% return.
