Introduction

LoanPro's platform is powered by a robust, custom-built calculator that provides all of the calculations that represent a loan or line of credit account—such as APR, full amortization schedules, daily interest accrual, statements, and more. When using LoanPro's UI or API to calculate loan values of any sort, the Loan Management System sends a request to the calculator, and its output is saved and stored within LoanPro.

However, the calculator can also be interacted with directly via its own API. Doing so allows users to use LoanPro's powerful calculator without interacting with LoanPro.

How the Calculator Works

The calculator is built as a stateless service that interacts with LoanPro, meaning it has no association with any environments and never stores the data that it outputs. The calculator's statelessness allows for short response times, but it requires that transaction history is provided if you'd like to calculate the values for an activated loan.

Using the API Calculator

LoanPro's API Calculator uses a similar format to the Loan Management System API. However, the API Calculator uses a separate base URL and a specific set of functions. To learn more about using the API Calculator, continue to Using the API Calculator →
