That was the same VAT man that told me I could claim a refund on the VAT for the half pint of shandy that I had bought him but had to pay the VAT on the drink I bought myself at the same time................. They are from another planet.alien

Not if you want "Proof of delivery" you can't and it's a foolish thing to post a VAT return without making sure you get a signature for it.

Humblest apologies for bringing this popular thread up again like, but i need a little bit of simple help from you mathmaticians.

How do i work out the initial cost of my combined invoices BEFORE VAT?
So, to simplify that, for example, VAT received from customers that I've invoiced: ?153.75., what therefore was the invoice total BEFORE the VAT was added at 15%, and also 17.5% for invoices handed out after 01/01/10?

Not happy with the way I've worded that ^^

?1000 + VAT @15% = ?1150, yes?

Simple formula required for working out the price before VAT which is obviously ?1000.

Same required for the 17.5 % rate too.

If VAT was at 15% divide total by 115 and multiply the answer by 100. That should give you the price before VAT was added.

Same applies if VAT was at 17.5%. Divide by 117.5 and multiply by 100 to get the pre-vat cost.

So ?153.75 divided by 115 = ?1.3369565

?1.3369565 multiplied by 100 = ?133.69565

Double check
?133.69565 + 15% = ?153.74999 which rounds up to ?153.75

Same sum but @ 17.5%

?153.75 divided by 117.5 = ?1.3085106

?1.3085106 multiplied by 100 = ?130.85106

Double check
?130.85106 + 17.5% = ?153.74999 which rounds up to ?153.75

Thank's Snoops. It's all coming back to me now from the last time I was VAT registered 6 years ago.

I'm sure MD will appreciate this too. lol:

Hang on, no. It's not working.
I've got a total VAT figure only here, and I need to work out what the cost was before the VAT was added.

You're assuming I've got a figure that's the total INCLUDING VAT. I've only got the VAT total that I've received from my cussies.

Don't understand...

Which is worked out the way Snoopy explained....

It's fun! lol:

OK.
I've got ?15 here (VAT received)
How do I work out what the invoice was before I added that VAT.

Same goes for another ?17.50 that I've got (17.5% VAT charged in this case)

Obviously the answers are simply ?100 in both cases, but what's the formula for working it out?
