Both C and D! Thanks

Krisso

C is calculated for example June - Actual costs £135,000 / June RPI x Jan API = 131897 (rounded to nearest £

D is calculated using the high/low calculation

14000 - 5000 = 9000
2000 - 200 = 1800

9000 / 1800 = 5 ( Value B )

Then to find the value of A multiple 5 by 2000 = £10000 and deduct this from £14000 = 4000 ( Value A )

Hope this helps
