Limitations:

Interest income can be affected by fluctuating interest rates, inflation, and changes in monetary policy. Additionally, it may not account for taxes on interest earnings, which can reduce the net income received.

However, it is subject to external factors like interest rate changes and inflation, which can impact its reliability as a sole measure of financial performance.
