Why investors speak in IRR

When a VC says "we target 30% IRR," or a real estate developer promises "25% IRR," they mean the annualised return that makes NPV = 0 on all the cash flows.

IRR is the lingua franca of investment returns because it:

  1. Accounts for time value of money
  2. Is scale-independent (% return, not absolute)
  3. Is comparable across projects of different sizes and durations

IRR benchmarks in India (2024)

  • Startup venture capital: Target IRR 25–40% (reflecting high failure rate)
  • Private equity (growth stage): Target 18–25%
  • Real estate development (plotted land/villas): Projected 20–30% (often overstated)
  • Listed equity (Nifty 50): Historical 12–14% CAGR
  • SME expansion (equipment, outlets): Acceptable 15–20%
  • Debt instruments: Bank loan rate + 3–5% risk premium

The reinvestment rate problem

IRR implicitly assumes that interim cash flows (year 1, year 2 returns) are reinvested at the same IRR. For high-IRR projects, this is unrealistic.

Example: A project with 30% IRR and large Year 1 cash flows assumes you can reinvest those flows at 30% — usually impossible. MIRR with a realistic 12% reinvestment rate would give a lower, more honest return figure.

For real estate developers reading this

Promoted IRRs on real estate projects often assume:

  • Full capital invested upfront (actual cash calls are phased)
  • Optimistic exit valuations
  • No holding period delays

Ask developers for the XIRR (Excel IRR for irregular cash flows) and verify exit cap rate assumptions independently.
