TSB Mortgage Calculator

The TSB Mortgage Calculator is a comprehensive tool designed to help you plan and manage your mortgage with TSB Bank across Ireland, New Zealand, and the United Kingdom. Whether you're a first-time buyer, an existing customer looking to switch, or an investor considering a buy-to-let property, this calculator provides instant results to help you make informed decisions.

Our TSB mortgage calculator covers multiple scenarios including standard repayment calculations, affordability assessments, buy-to-let analysis, overpayment planning, and mortgage switching. The calculator automatically adjusts for different regions, using the appropriate currency symbols and formatting for Ireland (EUR), New Zealand (NZD), and the United Kingdom (GBP).

For first-time buyers, the affordability calculator takes into account the typically higher borrowing capacity available, often allowing up to 3.5 times annual income compared to 3 times for other borrowers. The buy-to-let calculator helps investors assess rental yield and coverage ratios, which are crucial factors lenders consider when approving investment property mortgages.

The overpayment calculator shows you exactly how much interest you can save and how much time you can shave off your mortgage term by making extra payments. Whether you choose to make regular monthly overpayments or a one-time lump sum payment, you'll see the immediate impact on your total interest costs and loan term.

For existing TSB customers or those considering switching to TSB, the switch calculator compares your current mortgage terms with potential new terms. It calculates monthly savings, total interest savings, and the break-even period to help you determine if switching is financially beneficial. The calculator accounts for switching costs such as legal fees and valuation fees, giving you a complete picture of the financial impact.

All calculations include property tax and home insurance costs where applicable, providing a comprehensive view of your total monthly housing costs. The payment schedule feature shows a detailed month-by-month breakdown of your mortgage, including principal payments, interest payments, and any overpayments, with the ability to export the schedule to CSV for your records.

Whether you're using the TSB mortgage calculator app, accessing it online, or planning your mortgage switch, this tool provides accurate calculations based on standard mortgage formulas. Remember that actual rates and terms may vary based on your credit profile, property type, and other factors, so always consult with TSB or a qualified mortgage advisor for personalized advice.
