How this service works
Net present value and internal rate of return (IRR) for a list of cash flows, with a clear accept/reject-at-rate verdict.
Output
Returns NPV (numeric), IRR as a percentage, number of periods, payback period, number of sign changes in the cash flow series, a verdict string (accept or reject at the given rate), a plain-English summary, and optional disclaimer or degraded-mode flags.
Example use cases
Capital project accept/reject decision
“I'm evaluating a factory upgrade that costs $200,000 upfront and is expected to return $60,000, $70,000, $75,000, and $80,000 over the next four years. Using a 12% discount rate, should we accept or reject this project?”
Startup investment IRR check
“A startup pitch shows cash flows of -100000, 20000, 35000, 50000, 60000, and 70000 over five years. What's the IRR, and does the NPV look positive at a 10% discount rate?”
Real estate rental cash flow analysis
“I'm looking at a rental property with an initial outlay of -180000 and annual net cash flows of 22000 for each of the next seven years. Can you compute the NPV at 8% and tell me the internal rate of return and payback period?”
Technical details
Endpoint
GEThttps://finance-calculators.x402tookit.com/npv-irr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, paid-API-quality NPV and IRR computation with a built-in accept/reject verdict rather than implementing the math yourself. It is especially useful for AI agents performing investment screening, capital budgeting, or financial planning tasks where a clear recommendation at a stated discount rate is needed alongside the raw numbers.
Side effects
- Missing required 'flows' parameter returns an error
- Too many cash flow periods (over 60) may be rejected
- Non-numeric values in the flows string cause parse errors
- Cash flows with no sign change may yield no valid IRR (irrPct returned as null)
- Unusual cash flow patterns (multiple sign changes) may produce multiple IRRs or unreliable IRR; service may flag this via signChanges field
