Compute the standard commercial real estate underwriting metrics from raw figures: NOI, cap rate, DSCR, debt yield, LTV, LTC, operating expense ratio, break-even occupancy and yield on cost. Supply whatever you have — each metric is returned only when its inputs are present, with the formula used. Use this instead of computing CRE ratios yourself.

## Request body

- object
  - `annualRevenue` number: Gross/effective annual revenue
  - `annualExpenses` number: Annual operating expenses (excl. debt service)
  - `netOperatingIncome` number: Supply directly, or let it derive from revenue - expenses
  - `propertyValue` number
  - `purchasePrice` number
  - `totalProjectCost` number: For LTC and yield-on-cost
  - `loanAmount` number
  - `annualDebtService` number: Annual, not monthly
  - `rate` number: DECIMAL (0.0725 = 7.25%), used to derive debt service
  - `amortizationYears` integer

## Response `200`

The computed result.

- object
  - `tool` 'calculate_metrics', required
  - `deterministic` boolean
  - `result` object, required: Result fields: netOperatingIncome, annualDebtService, capRate, dscr, debtYield, ltv, ltc, operatingExpenseRatio, breakEvenOccupancy, yieldOnCost, formulas, missing.
