Mortgage

Understanding how mortgage loans work and how payments are calculated

What is a mortgage?

A mortgage is a long-term loan used to purchase real estate. The borrower repays the loan over time through regular payments that include both principal and interest.

How do mortgage payments work?

Mortgage payments are typically made monthly and consist of two main components: principal (the borrowed amount) and interest (the cost of borrowing). Early payments are interest-heavy, while later payments reduce principal faster.

Key factors that affect a mortgage

Several factors influence mortgage payments and total cost, including:

Example of a mortgage calculation

Loan amount: $250,000
Interest rate: 5%
Loan term: 30 years

Estimated monthly payment ≈ $1,342

Why mortgage planning matters

Choosing an affordable mortgage helps prevent financial stress and long-term debt problems. Understanding mortgage mechanics allows borrowers to compare offers and plan housing costs accurately.

Can mortgage costs change?

Yes. Variable interest rates, refinancing, and additional payments can all change total mortgage cost over time. Regular review of mortgage terms is recommended.
