How It Works
Real return is calculated by subtracting the inflation rate from your nominal return. The formula is: Real Return = Nominal Return – Inflation Rate. If you earned a 15% return on an investment but inflation was 3%, your real return is approximately 12%. This adjustment matters because inflation silently erodes purchasing power. A 7% return during high inflation (say 6%) delivers only 1% real return—barely beating cash savings. Conversely, a 5% return with 1% inflation gives you a 4% real return, meaningfully growing your wealth.
Why It Matters for Investors
Angel investors must think in real returns because nominal numbers deceive. A portfolio showing 8% annual gains looks respectable until inflation runs 5-6%, leaving actual wealth growth minimal. Real return is especially critical for long-term investments like venture equity, where you're committing capital for 7-10 years. If your startup exits at 3x return over a decade, but inflation averaged 2.5% annually, your real return drops significantly. Understanding this distinction helps you set realistic performance benchmarks and compare opportunities fairly. Comparing a real estate investment yielding 6% nominal to an early-stage equity position requires converting both to real returns for accurate appraisal.
Example
Imagine you invest $100,000 in a Series A round. After five years, your stake is worth $250,000—a 150% nominal return, or 20% annually. Impressive on paper. But if average inflation over those five years was 3% annually, your real return was closer to 17% annually. That $250,000 buys less than it would have in a zero-inflation scenario. Now consider a different scenario: a 12% nominal return with 5% inflation yields only 7% real return. The second investment might outperform the first in real terms despite lower nominal gains. This is why sophisticated investors track inflation-adjusted returns.
Key Takeaways
- Real return adjusts investment gains for inflation, showing true purchasing power increase
- Calculate it by subtracting inflation rate from nominal return
- Nominal returns can be misleading—a 10% gain with 8% inflation is actually just 2% real return
- Angel investors should evaluate exit multiples and holding period returns in inflation-adjusted terms for accurate opportunity comparison
- Real return expectations should exceed historical inflation rates (typically 2-3%) to justify investment risk
