How to Calculate GST Manually, Assuming a GST Rate of 10%

To calculate GST at 10% rate: just multiple your GST exclusive amount by 0.1
$500 is GST exlusive value
$500 * 0.1 = $50 GST amount
To get GST inclusive amount multiply GST exclusive value by 1.1
$500 is GST exlusive value
$500 * 1.1 = $550 GST inclusive amount
To get GST part of GST inclusive amount you need divide GST inclusive amount by 11
$220 is GST inclusive value
$220 / 11 = $20 GST value
To get GST exclusive amount while knowing GST inclusive value you need to multiply GST inclusive price by 10 ant then divide result by 11
