UK Property Buying Calculators

Buying a property in the UK involves dozens of financial decisions, each one building on the last. Before you even start viewing homes, you need a clear picture of what you can afford, what the total cost will look like, and how different scenarios affect your monthly budget over the years ahead.

The journey typically begins with affordability. Lenders assess your income, outgoings, and deposit to determine how much they will lend. Our mortgage affordability calculator models this process so you can set a realistic budget before approaching a broker. Once you know your price range, the mortgage calculator shows exactly what your monthly repayments will be across different terms and interest rates, while the interest-only mortgage calculator lets you compare the cost of repaying just the interest during the term.

Stamp duty is one of the biggest upfront costs that catches buyers off guard. The rates differ depending on whether you are a first-time buyer, purchasing a second home, or buying in Scotland or Wales. Our stamp duty calculator covers all of these scenarios with SDLT, LBTT, and LTT variants, plus a dedicated first-time buyer calculator that applies the current relief thresholds. If you have recently sold a previous main residence and believe you are owed a refund on the higher rate, the stamp duty refund calculator walks you through the claim.

For those looking beyond their own home, the buy-to-let mortgage calculator factors in rental yield expectations and the stricter lending criteria that apply to investment properties. The capital gains tax calculator then shows what you would owe when selling an investment property, taking the annual exempt amount and your tax band into account. If you are thinking long term about passing property wealth to family, the inheritance tax calculator estimates the liability on your estate and models how gifts, trusts, and reliefs reduce the bill.

Shared ownership and Right to Buy open routes to the property ladder that work differently from a standard purchase. Our shared ownership calculator models staircasing -- the process of buying additional shares over time -- while the Right to Buy calculator shows the discount available to qualifying council tenants and what the net purchase price would be.

Finally, the loan-to-value calculator helps you understand how your deposit size affects the rates you are offered, and the mortgage overpayment calculator demonstrates how even small extra payments each month can shave years off your term and save thousands in interest. Together, these tools give you a complete financial map of the property buying journey from first enquiry to final payment.
