How this service works
QuantOracle: tvm/irr
Output
Returns the IRR as a decimal and percentage, the number of periods, the NPV at the computed IRR (should be ~0), total amount invested, total cash received, and the profit multiple (total received / total invested). Also includes computation time in milliseconds.
Example use cases
Example prompt
“What's the IRR on an investment where I put in $10,000 upfront and receive $3,000, $4,000, $4,500, and $5,000 over the next four periods?”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/tvm/irrWhen to prefer
Use this endpoint when you need a fast, precise IRR calculation from a known cash flow series, especially in financial modeling, project evaluation, or investment screening workflows. Prefer it over spreadsheet tools or manual iteration when automating capital budgeting or portfolio analysis pipelines.
Side effects
- No sign change in cash flows (all positive or all negative) — IRR cannot be computed, returns error
- Non-convergence when cash flows have multiple IRR solutions (non-normal cash flows)
- Empty or single-element cash_flows array — insufficient data for IRR
- Invalid data types in cash_flows (non-numeric values)
