Rather than jump on the back of an old thread with no replies for more than five years, I've created a new topic for you.

 

I'm not sure what you're actually asking, please elaborate?

You can check this doc regarding the financial requirement

 

Quote

7.2.2. At the entry clearance/initial leave to remain stage and the further leave stage, the amount of cash savings above £16,000 must be divided by 2.5 (to reflect the 2.5 year or 30- month period before the applicant will have to make a further application) to give the amount which can be used in meeting the financial requirement. The following equation is to be used:

 

(x minus 16,000) divided by 2.5 = y

 

Where x is the total amount of cash savings held by the applicant, their partner, or both jointly for at least the 6 months prior to the date of application and under their control.

 

And y is the amount which can be used towards the financial requirement.

 

As far as I can see you are £6300 short of the £18600 needed per year.   What that means in terms of cash savings required to make up the shortfall is £31750.
