When to use this calculator
- Before buying, renting, refinancing or reviewing a property investment.
- When you want to compare cash flow, tax, yield or ownership costs.
- When you need a fast estimate before speaking to an agent, lender or adviser.
- When you want to see how a rate or price change moves the result.
Example: total cash needed to complete a home purchase
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Purchase price | £275,000 |
| Variable tax / SDLT input | £4,750 |
| Legal fees | £1,450 |
| Survey fees | £650 |
A mortgage payment can look fine and still leave the purchase short on completion day. This example is about the cash required to actually finish the deal.
Method & assumptions
This calculator estimates purchase-side costs by combining a percentage of the price you enter with any fixed legal and survey fees you enter. It does not apply a country-specific property-tax table. Use it to total the cash you need on top of the purchase price, then use a jurisdiction-specific transfer-tax calculator when you need statutory bands.
Common mistakes
- Comparing rent and ownership costs without including taxes, fees and maintenance.
- Using purchase price alone without testing financing or vacancy assumptions.
- Relying on yield or growth in isolation instead of reviewing the full property case.
- Using the wrong national transaction-tax calculator for the purchase location.
What to do next
- Run a second scenario with a higher rate or lower rental yield.
- Compare the result with a buy-versus-rent or mortgage calculator before making an offer.
- Use the matching national transaction-tax calculator for the purchase location.
- Note the key figures to share with your solicitor or lender.
