What does a 'good' yield or ROI mean?

Yield and return on investment (ROI) are often discussed using qualitative terms such as 'good', 'high', or 'low'. In practice, these terms are context-dependent and can mean different things depending on assumptions and circumstances.

Key Takeaways

  • 1There is no universal 'good' yield or ROI
  • 2Yield and ROI measure different aspects of performance
  • 3Risk, costs, and financing structure affect how figures are interpreted
  • 4Comparisons are most meaningful when assumptions are consistent

Yield is a comparison metric

Yield measures rental income relative to the purchase price of a property.

Because yield does not account for financing or most costs:

  • It is often used to compare properties at a high level
  • It does not indicate profitability or cash flow on its own
  • The same yield can produce very different outcomes once costs are included

Yield is best interpreted as a relative measure, not an absolute judgement.

ROI reflects efficiency of invested cash

ROI measures annual profit relative to the total cash invested.

Because ROI includes financing and costs:

  • It is sensitive to assumptions
  • Small changes can materially affect results
  • It varies significantly between cash and mortgaged purchases

ROI is best interpreted in relation to how much cash is committed and how returns are generated.

Why ranges are not universal

Published ranges or benchmarks for yield and ROI often vary because they depend on:

  • Property type and location
  • Financing structure
  • Cost assumptions
  • Market conditions at a given time

As a result, values described as "good" in one context may not be comparable in another.

Risk and stability matter

Higher yields or ROIs often come with:

  • Greater sensitivity to costs or interest rates
  • Less margin for error
  • Higher variability in cash flow

Lower yields or ROIs may reflect:

  • More stable assumptions
  • Lower exposure to changes
  • Different trade-offs between cash flow and risk

These trade-offs are not captured by a single number.

Using yield and ROI responsibly

Yield and ROI are most useful when:

  • Compared across properties using the same assumptions
  • Viewed alongside monthly and annual profit
  • Used to understand trade-offs rather than to rank outcomes

They are less useful when treated as targets or standalone indicators.

How the calculator presents these figures

The calculator displays yield and ROI based on the same rental, cost, and financing assumptions. Adjusting inputs shows how sensitive these figures are to changes in assumptions.

This helps place yield and ROI in context rather than treating them as fixed benchmarks.

Summary

There is no single definition of a "good" yield or ROI. Both metrics are context-dependent and should be interpreted alongside cash flow, costs, and assumptions. Understanding how the figures are calculated and what they represent is more important than comparing them to a fixed threshold.
