How do I calculate interest paid on a working capital loan?

[AeroTwin7]

I have a working capital loan for 24,000. Interest charged $10,386. Total I owe is $34,386. I've paid 10,369 back this year. What part of is considered "interest" for tax deduction?

You should deduct the actual amount of interest you paid in 2016-$10,369.

All of that 10,369 is not interest - some of that is the loan. Payment consists of principal +  interest ideally.

So noted, interest actually paid in 2016, is tax deductible as a business expense.
