How this service works
Loan payment calculator. Computes the fixed monthly payment for a standard amortizing loan and returns the full month-by-month principal/interest/balance schedule — exact amortization math an LLM cannot reliably compute by hand for hundreds of periods.
Output
Returns the fixed monthly payment amount and a complete amortization schedule listing each period's principal portion, interest portion, and remaining loan balance — covering every month from period 1 through the final payoff.
Example use cases
Mortgage payment planning
“I'm buying a house and taking out a $400,000 mortgage at 7% annual interest over 30 years — what will my monthly payment be and can I see how the balance decreases month by month?”
Car loan breakdown
“I'm financing a $35,000 car loan at 5.9% annual rate for 5 years. Show me the exact monthly payment and the full amortization schedule so I can see how much goes to interest vs principal each month.”
Early payoff analysis
“I have a $150,000 personal loan at 8% annual interest over 10 years. Give me the complete month-by-month amortization table so I can figure out how much principal I'll have paid off by year 3.”
Technical details
Endpoint
POSThttps://x402.outpimp.com/loanPaymentCalculatorWhen to prefer
Choose this endpoint when you need mathematically precise, period-by-period amortization schedules that an LLM cannot reliably compute by hand — especially for long loan terms (e.g. 240–360 periods). Prefer it over manual LLM arithmetic whenever the user needs the exact monthly payment figure or a full breakdown of how principal and interest are allocated each month. It is purpose-built for standard fixed-rate amortizing loans.
Side effects
- Missing required fields (principal or annualRate) return a validation error
- annualRate provided as a percentage integer (e.g. 6) instead of a fraction (0.06) will produce wildly incorrect results
- termYears outside the 1–50 range may return an error or unexpected behavior
- Zero or negative principal/rate values may cause computation errors
- Network or payment authorization failure returns a 402 or connectivity error
