    Hi All,
    Going to ask an incredibly silly question - maybe I have brain freeze or should have paid more attention in maths. I costed up some shiplap however my spreadsheet comes out to a totally different cost to what the supplier sent:
    I am being quoted £1.75 per Linear Metre. Now I thought this to be the same as a standard metre.
    The length of wood required in this example is 3.0.
    On the invoice I have a unit price for this of 4.38 and for the 30 lengths a cost of £131.40
    I cant arrive at that cost, I thought it would be £1.75 *3.0 for the cost of a 3M length (5.25)
    and then * by 30 lengths for a total cost of £157.
    I know my way is more expensive but I am just trying to understand what I have got wrong. I have added/minused VAT but this doesn't get me to the same figures which were quoted.
    What am I doing wrong?

    £4.38 + VAT = £5.25
    £131.40 + VAT = £157.68

    Did they actually charge you the VAT?

    VAT is 20% so multiply / divide by 1.2

    and just like that order is restored in the universe. You are absolutely correct. The VAT was throwing me. It was included in the final total, hence I was unable to arrive at the quoted figures. Its makes perfect sense now. Thanks again for that, appreciate it.
    KIAB and Dr Bodgit like this.

    You're right, a linear metre is a standard metre. They have stated that as it might be confused with a square metre - entirely possible with something like shiplap.

    ...and you have made allowance for the "lap" haven't you? - don't forget you lose a little board width when calculating how many you need.............
