I want to do a calculation on
qty * rate = amount
amount - discount + taxes = bill amount
bill amount + round off = net amount

I know it can be done easily, but the problem is that any one can change the value through inspect element. To stop that I have to recalculate the values again in server
side and this will make the work duplicate and increase the chances of error from developer side.


please suggest me the right way...

The right way is to do both client and server side validation. Never rely exclusively on client side validation because it can be altered or hacked.

Do the calculation on client side but then verify it on server side.
