How this service works
Mortgage and loan payment calculator: enter principal, annual rate, and term to get the exact monthly payment, total amount paid over the life of the loan, and total interest owed. Built for home-buying estimates, amortization sanity checks, and personal-finance planning agents that need real numbers instead of a rough guess. Not financial advice — just exact arithmetic on the inputs you give it.
Output
Returns the exact monthly payment amount, the total amount paid over the full loan term, and the total interest owed — computed arithmetically from the provided principal, annual rate, and term inputs.
Example use cases
Example prompt
“Can you calculate the exact monthly payment, total paid, and total interest for a $450,000 mortgage at 6.75% annual interest over 30 years?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/mortgage-calculatorWhen to prefer
Use this endpoint when you need exact, deterministic arithmetic for mortgage or loan payment calculations — especially for home-buying estimates, amortization planning, or any personal finance agent that requires precise numbers rather than approximations. Prefer this over general-purpose LLM math when exactness matters.
Side effects
- Missing required fields (principal, annual_rate_percent, years) return an error or zero/null result
- Non-numeric string inputs may cause calculation errors
- Very unusual term lengths or edge-case rates (0% or negative) may produce unexpected results
- The calculation type enum must match one of: compound_interest, loan_payment, roi — wrong values may return incorrect calculation
