SDLTM13215 - Calculation of stamp duty: Rent: Variable or uncertain rent: Example 4

A lease for a term of four years is granted on 1 April 2018, with an initial rent of£100,000 per annum which is increased by 4% per year.

The net present value (NPV) of this lease is calculated on the basis of the rent increasesfor each year as they are:

  • known at the date of grant;
  • within the first five years of the term of the lease; and
  • not calculated in line with RPI

The figures of rent for the NPV calculation are therefore:

Year 1 £100,000
Year 2 £104,000
Year 3 £108,160
Year 4 £112,486

The calculation will not require review because the known rent increases are included inthe original NPV calculation and are not estimated or contingent.
