How much compression does RAR add to an uncompressed tarball?

A lot when the contents are compressible — since TAR applied none, RAR's encoder works on raw data, and text-heavy tarballs often shrink 60-80%. Payloads that were already compressed inside the tar, like images or .gz files, barely move.

Do recipients need paid software to open the RAR?

No — reading RAR is free everywhere: 7-Zip, PeaZip, and The Unarchiver all extract it without a license. It's writing RAR that requires the proprietary encoder. The caveat is that no operating system opens RAR out of the box, so recipients must have one of those tools installed.

Why pick RAR over the usual gzip for a tarball?

Two features gzip lacks: recovery records, which embed parity data that can repair a damaged download, and multi-volume splitting into fixed-size parts for large transfers. For distribution over unreliable connections those matter; for Unix-internal use, .tar.gz stays the simpler choice.
