Backend Formula for the Mortgage Overpayment UK Calculator
The formula behind the **Mortgage Overpayment UK Calculator** is critical in determining the financial impact of overpayments. Here’s how it works:
Step-by-Step Breakdown: The calculation uses the following formula:
- Monthly Payment Calculation: Uses P = L[c(1 + c)^n] / [(1 + c)^n – 1], where P is the monthly payment, L is the loan amount, c is the monthly interest rate, and n is the number of payments.
- Adjust for Overpayment: Add the overpayment amount to the monthly payment.
- Iterative Balance Calculation: Reduce the principal by the adjusted payment and accrue interest monthly until the balance is zero.
Illustrative Example: Consider a £200,000 mortgage at a 3% annual interest rate over 25 years, with a £100 monthly overpayment. The original term results in a monthly payment of about £948.42. Adding £100 reduces the term significantly and saves thousands in interest.
Common Variations: Some calculators might use different compounding periods (e.g., daily vs. monthly), but this one assumes monthly compounding for simplicity and consistency.
