Step by step
Open Stamp Duty (SDLT) Calculator
Visit /uk/tools/uk-stamp-duty in any modern browser. The tool loads instantly and runs entirely on your device, so no inputs are transmitted to a server.
Gather your inputs
Have your tool specific input fields ready. Accuracy on the output depends entirely on the quality of these numbers. If a value is uncertain, use the most realistic figure rather than rounding aggressively.
Enter the values
Fill each field in turn. Stamp Duty (SDLT) Calculator validates ranges as you type, so an obvious typo (for example a negative balance where one cannot exist) will flag immediately.
Read the result
The output is a stamp duty (sdlt) result, derived from the inputs above, computed using domain specific formula. Treat it as a precise answer to the question you posed, not an approximation.
Verify and compare
Re-run the calculation with a slightly different input to test sensitivity. For deeper comparison against another approach, see related tools in the UK Finance hub or pick a related stamp duty (sdlt) tool below.
