During booking of expenses its wrong calculation doing. Please help to resolve.

There are possible reasons why an expense is calculating incorrectly, @sanoj-tokenz-com.

When you create the expense, and the item's amount is incorrect, be sure to review the cost rate and account used.

Here's how: 

1. Go to the Sales tab on the left side. 
2. Choose Product and Services. 
3. Find the purchase name, then click Edit under Action. 
4. Check the amount. If it's wrong, make necessary changes, then hit Save and Close.  

Also, check if the expense is taxable or not. The calculation may depend on the tax rate you're using.

If the same problem, I'd suggest performing troubleshooting steps. At times, the stored data can cause some issues in your browser's web pages. 

You can press the following keyboard shortcuts : 

• Ctrl+ Shift + N (Google Chrome)
• Ctrl + Shift + P (Mozilla Firefox)
• Ctrl + Shift + P (Internet Explorer)
• Command + Shift + N (Safari)

Once logged in, go back to the expense page and re-create to check if the amount is correct. If that works, you can clear the cache depending on which browser you're using through this helpful article: Delete Temporary Internet Files. Clearing the cache or cookies is the best way to get a clean slate. Using another compatible browser is a good alternative too.
