Custom Fields - Complex IF formulas

JFDex

I am looking to move our sales CRM to Pipedrive.

Our deals are usually home loans, and we require a custom field to calculate loan repayments over a period of time.

The repayments are also dependant on loan repayment frequency (weekly, fortnightly, half-monthly & monthly).

Is there a way to set up a custom IF formula to accomodate these variances?

Alternatively, is there an app that allows the connection of complex formulas/loan fields?

There used to be a 3rd-party integration. Not sure if it is around anymore.

Better to use Make/Integromat or Zapier or Relay.app.
