Описание:

The plan was to make a nicer looking version of http://www.propyield.com/#calculator and also brand it up so it fits within your site.


Calculations message from Accountant:

Attached is the model which is based upon the model in Propyield but the stamp duty calculator in that model is incorrect. Hence, the calculator in KnightFrank is used (http://www.knightfrank.co.uk/stamp-duty-calculator)



Propyield

The variables are constants for all values from zero to infinity

Agency - 1.0%

Legal – 0.75%

Other – 0.57%

These are show in columns “I-L” on the attached spreadsheet



Stamp Duty

Cross checking of Knight Frank is shown on columns “S-Y” on the attached spreadsheet.

There needs also to be a ‘trigger’ in the model for the property being (i) residential buy to let (ii) commercial (Y/N)

Where it is a Residential BTL the model needs to add 3% to the rate on all stamp duty levels.



The table is shown in Frank Knight.

The attached replicates this

The rates are shown in cells “S5:W5”

The thresholds are show in cells “S6:W6”

The rates are not ‘cumulative’ – eg it only applies to that threshold area – if you go over £125,000 the rate only applies to the excess above £125,000 and not on the whole amount
