When to use this calculator
- Before buying, renting, refinancing, or reviewing a property investment.
- When you want to compare cash flow, yield, growth, and ownership costs side by side.
- When you need a fast estimate before speaking to an agent, lender, or adviser.
- When you are assessing whether a rental property still makes financial sense after a mortgage rate change.
- When you want to compare the total cost of renting against owning over a five- or ten-year horizon.
Example: modelling a property tax bill
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Property value | £300,000 |
| Tax rate | 1.5% |
| Tax estimate | £4,500 |
| Use case | Compare against completion and ownership costs |
The point of this example is not the exact rate; it is seeing how quickly a seemingly small percentage turns into a real cash amount.
How to read your results
Result
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Method & assumptionsAuthoritative sources
This calculator estimates Stamp Duty Land Tax (SDLT) for residential property purchases in England. It applies the standard tiered rate bands and automatically applies the additional-property surcharge where you indicate the purchase is a second home or buy-to-let. First-time buyer relief is applied when eligible, subject to the applicable price cap. The calculator does not cover Land and Buildings Transaction Tax (Scotland) or Land Transaction Tax (Wales), and does not account for linked transactions, mixed-use properties, or corporate purchaser rules, which can significantly alter the tax due. Figures are indicative and should be confirmed with a qualified conveyancing solicitor before exchange of contracts. Tax legislation changes frequently, so verify current thresholds with HMRC before relying on any estimate.

Common mistakes
- !Comparing rent and ownership costs without including taxes, fees, and maintenance.
- !Using purchase price alone without testing the impact of financing or vacancy assumptions.
- !Relying on yield or growth in isolation instead of reviewing the full property case.
- !Forgetting Stamp Duty Land Tax (or its Scottish and Welsh equivalents), which can add thousands to the true cost of purchase.
- !Using optimistic rental growth figures without also testing a flat or declining rent scenario to check downside resilience.
What to do next
- Run a second scenario with a higher rate or lower rental yield to check downside resilience.
- Compare the result with a buy-versus-rent or stamp duty calculator before making an offer.
- Use the related guides below to understand agent fees, legal costs, and ongoing maintenance budgets.
- If you are assessing a buy-to-let, check the gross yield against the net yield after mortgage interest, voids, and management fees.
- Note down the key figures from this scenario to share with your solicitor or mortgage broker so they are working from the same assumptions.
