1. What is a Central Heating Finance Calculator?

Definition: This calculator computes the monthly payment amount for financing a central heating system based on loan amount, interest rate, and term length.

Purpose: It helps homeowners and contractors determine affordable payment plans for heating system installations or upgrades.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:
