Adding Payment Processing Fee to Gravity Forms Checkout

THIS POST MAY CONTAIN AFFILIATE LINKS. PLEASE READ OUR DISCLAIMER FOR MORE INFO.

If you are using Gravity Forms to collect payment for a service or to sell a product, or to collect donations you know that the payment processors, such as Stripe, Square, PayPal, all charge a fee. That fee is usually somewhere around 2.9% +.30.

We can’t make the fees go away, unfortunately, but if you’d like to pass that fee onto your customer or donator you can do that with a product field and a simple formula.

Setting up Your Form

The first step is to add another product field to your form. However, this field needs to be set to the Calculation field type:

Once the field is ready, you will need to add the formula below to the product field:

( {Product Field:ID} + .3 ) / (1 - .029) - {Product Field:ID}

You will need to switch out the {Product Field:ID} merge tag with your actual product field price merge tag:

Once the form is setup and saved, you will be able to pass the processing fee along to the customer.

The best part about using this specific formula is that the outcome is a perfect price split, your original product price, and the processing fee, as shown in the Stripe payment details below:

FAQs

What if you have multiple products?

You can add multiple products to the processing fee calculation formula. As demonstrated here:

Can you give the user the option to cover the processing fee?

Sure! If you add a radio button field to the form asking the user if they want to cover the fees and add conditional logic to the processing fee product to show/hide it depending on the users selection.

I am using this for an event registration. It is possible for certain users to select options that would reduce their price to 0, letting them register for free. In this case, their subtotal is $0 but, due to the processing fee calculation that is added on, it still charges them a fee of $0.31. How can I remedy this? I thought the answer may lie in conditional logic somehow, but can’t figure it out since I can only select one “total” field for the payment amount in the Stripe feed setup.

Hi Chris,

I wondered how you handle the two types of Stripe fees? For us in AU and I think elsewhere Stripe has the below:

1.75% + A$0.30 for Domestic cards
2.9% + A$0.30 for International cards

I can see from your calcs. above it looks like you only do one calculation?

Any response would be greatly appreciated!

Cheers I used this on a project today Chris!

Having the same issue as Tom, though being in Australia.

I wonder if you can block international cards in Stripe?

Most people use Visa or Mastercard in Australia for small business so if you can reject other cards that would work.

I think the fees are less for normal debt cards vs credit cards? which needs to be taken into account if so.

Probably have to ask the customer directly what card do you have with a drop down. A lot of logic but doable. If anyone has a work around keen to hear.

Can the Quantity: field on a Product be figured into the total? On my form, the page is letting parents order a year book — or a few year books, depending on whether they have a couple of kids in that school. It shows only the $1.35 for a single purchase — nothing changes when the Quantity is increased — I’d imagine there would be a “times” component added to the snippet?

Hey, do you think this fee recovery solution would work with recurring donations?

And doesn’t it require 2 different Stripe feeds, one with fees and one without?

Hi there, how do you do this when you have multiple products? There’s no way I can find to do the calculation off a total field…
