Kotlin vs Ruby on Rails: which pays more?
The median for Kotlin is $196,000 per year (typically $156,750–$203,750), versus $119,233 for Ruby on Rails ($90,350–$146,250). That puts Kotlin about 64% ahead at the median.
Both figures are computed live from active listings on JobsRadar and normalized to annualized USD, so Kotlin and Ruby on Rails are compared on equal terms regardless of the currency each role was originally posted in. Only roles that publish a salary range feed the medians; numbers refresh every few hours as new roles post and older ones close, so this comparison reflects the market right now rather than a fixed survey. Use it as a directional benchmark when weighing one path against the other.
