1. What is the Martin Lewis Mortgage Formula?

The Martin Lewis mortgage formula is a standard calculation used to determine monthly mortgage payments based on loan amount, interest rate, and term length. It's the same formula used by most mortgage lenders to calculate repayments.

2. How the Calculator Works

The calculator uses the standard mortgage formula:

Where:

• \( Loan\ Amount \) — Total amount borrowed
• \( Interest\ Rate \) — Annual interest rate (as decimal)
• \( Term\ in\ Months \) — Loan duration in months

Explanation: This formula accounts for compound interest over the life of the loan to calculate fixed monthly payments that will pay off the loan by the end of the term.

3. Importance of Mortgage Calculation

Details: Understanding your potential mortgage payments helps with budgeting, comparing loan offers, and determining how much you can afford to borrow.

4. Using the Calculator

Tips: Enter the loan amount, annual interest rate (as percentage), loan term in years, and select your currency. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this include taxes and insurance?
A: No, this calculates principal and interest only. Your actual payment may include property taxes, insurance, and other fees.

Q2: How does interest rate affect payments?
A: Higher rates increase monthly payments significantly. A 1% rate increase can raise payments by 10% or more on a 30-year loan.

Q3: What's better - shorter term or lower rate?
A: Generally, a lower rate saves more money overall, but shorter terms build equity faster and pay less total interest.

Q4: How accurate is this calculator?
A: It provides exact calculations for fixed-rate mortgages. For adjustable-rate mortgages, it only calculates initial payments.

Q5: Can I calculate extra payments?
A: This shows standard payments only. Extra payments would require a more advanced amortization calculator.
