Highlights
- A method for calculating rates of return by compounding interim returns.
- Used in investment performance measurement to ensure accuracy over time.
- Helps investors assess cumulative returns without distortions.
The linking method is a widely used technique for calculating rates of return by sequentially multiplying interim returns over multiple periods. This approach ensures an accurate representation of an investment’s cumulative growth while accounting for variations in performance across different time frames.
Where R₁, R₂, ..., Rₙ represent the interim rates of return for each period. This method prevents misrepresentation of returns by ensuring that each period’s gain or loss is factored into the next.

- Accurate Return Measurement – Reflects the true effect of compounding on investment growth.
- Comparable Performance Analysis – Standardizes return calculations for fair comparisons across investments.
- Fair Benchmarking – Ensures that performance metrics align with industry standards.
Real-World Applications
The linking method is commonly used in:
- Mutual Fund and Portfolio Performance Reporting – Ensures consistency when tracking investment growth over time.
- Pension Fund and Institutional Investments – Helps fund managers assess long-term returns accurately.
- Financial Planning and Forecasting – Provides realistic return projections for investors.
Conclusion
The linking method is a critical tool for calculating investment returns accurately over multiple periods. By compounding interim returns, it provides a true reflection of cumulative performance, helping investors make informed decisions. Its ability to maintain accuracy and consistency makes it an essential method in financial analysis and portfolio management.
