How this service works
QuantOracle: tvm/npv
Output
Returns the computed NPV (e.g. 5297.52), the number of periods, a decision recommendation (ACCEPT or REJECT), payback period, profitability index, and an array of individual present values for each cash flow period.
Example use cases
Example prompt
“What's the NPV of a project with cash flows of $1,000, $2,000, and $3,000 over 3 years using a 10% discount rate — and should I accept or reject it?”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/tvm/npvWhen to prefer
Use this endpoint when you need fast, programmatic NPV computation with a built-in ACCEPT/REJECT decision signal and per-period present value breakdown. Prefer over generic finance libraries when you need a pay-per-call API with no setup, especially for agent workflows performing capital budgeting or investment screening at scale.
Side effects
- Invalid or empty cash_flows array — returns error
- discount_rate missing or non-numeric — returns validation error
- Negative discount rates may produce unexpected results
- Very large cash flow arrays may exceed processing limits
