How can I calculate product price based on letter count?

Hi, I’m designing my florist website and needed an app to help me do the following.

I have some floral letters priced at £30. Once my customer enters the word they require I want the amount of letters they have entered to multiple with the price of each letter £30.
if someone wants the word DAD, I would need the following to happen

D A D = 3 letters

£30 x 3 = total

If their is an app available I would love to know!

Hello @BelleRose1 , Have you got your solution? As you want to update the price according to the amount of letters that your customer enters then you can try the Inkybay app.

You can also set the price per character for a text that your customer will enter on a custom product. Suppose you’ve set $2 per character, and a word consist of 5 characters then the customizing price will be 5*2=10 in total.
