Need Help with VAT Reverse Calculator

Hey everyone,

I'm facing a bit of a dilemma with VAT reverse calculation and could use some guidance. Here's the scenario: I have the total amount including VAT, but I need to figure out the original price before VAT was added. I've tried a few online calculators, but the results seem inconsistent.

Could someone please recommend a reliable VAT reverse calculator or share a foolproof method to calculate this manually? Your expertise would be greatly appreciated! I'm eager to learn and get this right. Thanks in advance for any help or advice you can offer!
