Calculating Monthly Expenses for Visitor Visa Application Purposes

Hi!

For my UK visitor visa application I’m calculating my monthly expenses and I’m just curious if my methodology would make sense to the visa officer.

So, I’m going to calculate an average of my spendings for last three months.

However, I’m going to exclude:

- my phone bill and gym membership fees as they are reimbursed by my employer (this is shown in my payslips)

- the transactions that are basically me sending money from my regular spending account to my savings account.

- one time transaction for my home insurance.

- And plane tickets and Airbnb reservation fees I paid for the planned trip.

I will explain all of this in my cover letter. Do you think this methodology and justifications are reasonable?
