How to Use This Calculator
  1. Start by filling in the input fields below. Results update instantly as you type, so you can experiment with different values to see how they affect the outcome.
  2. Initial Investment — The upfront investment amount (entered as positive). Accepts values from $1 to $100,000,000 (default: $100,000).
  3. Year 1 Cash Flow — Net cash flow in year 1 (positive for inflow). Accepts values from $-10,000,000 to $100,000,000 (default: $25,000).
  4. Year 2 Cash Flow — Net cash flow in year 2. Accepts values from $-10,000,000 to $100,000,000 (default: $30,000).
  5. Year 3 Cash Flow — Net cash flow in year 3. Accepts values from $-10,000,000 to $100,000,000 (default: $35,000).
  6. Year 4 Cash Flow — Net cash flow in year 4. Accepts values from $-10,000,000 to $100,000,000 (default: $40,000).
  7. Year 5 Cash Flow — Net cash flow in year 5 (include exit value if applicable). Accepts values from $-10,000,000 to $100,000,000 (default: $50,000).
  8. Once all inputs are set, review your results in the Results panel. Here's what each output means:
  9. Internal Rate of Return (IRR) — The discount rate that makes NPV equal to zero. This is the primary result of this calculator.
  10. Multiple on Invested Capital — Total returns divided by initial investment.
  11. Total Cash Inflows — shown as a dollar amount.
  12. Net Profit — Total inflows minus initial investment.
  13. NPV at IRR — Should be approximately zero.
