Title: Incorrect calculation Last modified: September 2, 2022 --- # Incorrect calculation * Resolved [montyenglish](https://wordpress.org/support/users/montyenglish/) * (@montyenglish) * [3 years, 9 months ago](https://wordpress.org/support/topic/incorrect-calculation-3/) * Hi, I need to calculate price based on quantity of words for a proofreading service. The calculator is not multiplying correctly the price, might be a very silly mistake. The price was initially having decimals 0.012/word but I then changed it to see if that was causing the issue in the calculation. * Could you give me a help? * this is the formula: price {quantity} * {product_price} * Many thanks, Ludovica * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fincorrect-calculation-3%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Krzysztof Piątkowski](https://wordpress.org/support/users/wckalkulator/) * (@wckalkulator) * [3 years, 9 months ago](https://wordpress.org/support/topic/incorrect-calculation-3/#post-15978134) * [@montyenglish](https://wordpress.org/support/users/montyenglish/) Hi, please write your whole formula or better send me screen shots of your configuration. * The result of formula is the product price.

You named your field “quantity”, but {quantity} is reserved for default product quantity field (next to “add to basket” button). Use some other name, for example“ word_qty” and your formula will be {word_qty}*{product_price} * Thread Starter [montyenglish](https://wordpress.org/support/users/montyenglish/) * (@montyenglish) * [3 years, 9 months ago](https://wordpress.org/support/topic/incorrect-calculation-3/#post-15979811) * I updated the field and the formula but now the price keeps being £0 rather then updating depending on the quantity insert. Is there anything else that I am missing? * Plugin Author [Krzysztof Piątkowski](https://wordpress.org/support/users/wckalkulator/) * (@wckalkulator) * [3 years, 9 months ago](https://wordpress.org/support/topic/incorrect-calculation-3/#post-15980143) * [@montyenglish](https://wordpress.org/support/users/montyenglish/) it works. Just enter some number in input field and the price is updating. * Thread Starter [montyenglish](https://wordpress.org/support/users/montyenglish/) * (@montyenglish) * [3 years, 9 months ago](https://wordpress.org/support/topic/incorrect-calculation-3/#post-15980882) * The total price updates itself just if I click on it, is supposed to be this way? But it remains £0 regardless of the input.

You have one input field on product page, which is default 0. If I type “1” the price is £3,00 and it is updating. * Thread Starter [montyenglish](https://wordpress.org/support/users/montyenglish/) * (@montyenglish) * [3 years, 8 months ago](https://wordpress.org/support/topic/incorrect-calculation-3/#post-16004607) * So if I update the input and I type 1 or 3 etc the price stays 0, it updates correctly just if the input is 1 and I press the cursor up (also I didn’t notice there was a cursors before), but the input remains 1… The layout doesn’t seem to be user-friendly and also for the client is not working as should be. Any suggestion how to amend it? Otherwise we will switch to a general “ask for a quote” form.

POST request is sent when you leave field. I can change that behaviour to update price after some delay when user stays in the field. * You need to change styling by yourself.
