How the UK Mortgage Calculator Works
This mortgage calculator helps you understand your monthly mortgage payments and the total cost of your home loan. It uses standard mortgage calculation formulas used by UK lenders.
What You Need to Know
- Repayment Mortgage: You pay back both the capital (loan amount) and interest each month. By the end of the term, you'll own the property outright.
- Interest-Only Mortgage: You only pay the interest each month. You'll need to repay the full loan amount at the end of the term.
- Overpayments: Making extra payments can significantly reduce your mortgage term and save thousands in interest.
- Deposit: Most lenders require at least 5-10% deposit. A larger deposit usually means better interest rates.
Tips for First-Time Buyers
- Save for a larger deposit to access better rates
- Consider mortgage terms carefully - longer terms mean lower monthly payments but more interest overall
- Factor in additional costs like stamp duty, legal fees, and surveys
- Check if you qualify for first-time buyer schemes like Help to Buy
- Get a mortgage in principle before house hunting
