A very useful plugin, I recommend!
I use this add-on for Contact Form 7 in order to calculate fields of online sales certificate and it works very well. If you want advanced features (multiple calculated fields, intermediate variables...), then you will need the PRO version. But the investment is well worth the cost ;-)

Excellent plugin
The plugin is easy to use and the pro version allows you to make multiple calculated tags. It is a great addition to Contact Form 7. I'm using the pro version to calculate payment information for the customer along with the integrated Stripe checkout. Although the email and attached files are sent before checkout, there are separate redirect pages where the customer may be sent after successful or unsuccessful payment.
