+=item calc_recur CUST_PKG START_DATE DETAILS_ARRAYREF OPTIONS_HASHREF
+
+Calculates and returns the setup or recurring fees, respectively, for this
+package.  Implementation is in the FS::part_pkg:* module specific to this price
+plan.
+
+Adds invoicing details to the passed-in DETAILS_ARRAYREF
+
+Options are passed as a hashref.  Available options:
+
+=over 4
+
+=item freq_override
+
+Frequency override (for calc_recur)
+
+=item discounts
+
+This option is filled in by the method rather than controlling its operation.
+It is an arrayref.  Applicable discounts will be added to the arrayref, as
+L<FS::cust_bill_pkg_discount|FS::cust_bill_pkg_discount records>.
+
+=item real_pkgpart
+
+For package add-ons, is the base L<FS::part_pkg|package definition>, otherwise
+no different than pkgpart.
+
+=item precommit_hooks
+
+This option is filled in by the method rather than controlling its operation.
+It is an arrayref.  Anonymous coderefs will be added to the arrayref.  They
+need to be called before completing the billing operation.  For calc_recur
+only.
+
+=item increment_next_bill
+
+Increment the next bill date (boolean, for calc_recur).  Typically true except
+for particular situations.
+
+=item setup_fee
+
+This option is filled in by the method rather than controlling its operation.
+It indicates a deferred setup fee that is billed at calc_recur time (see price
+plan option prorate_defer_bill).
+
+=back
+
+Note: Don't calculate prices when not actually billing the package.  For that,
+see the L</base_setup|base_setup> and L</base_recur|base_recur> methods.
