Work out load balancer cost instantly with clear inputs, formula shown and shareable results.
Load balancer pricing charges an hourly base plus capacity units, where a unit is defined by whichever of four dimensions is highest: new connections, active connections, processed bytes and rule evaluations. You pay for the maximum, not the sum, so identifying the dominant dimension tells you what to optimise — usually connection reuse.
Capacity units
new connection units = rate / 25; active units = connections / 3000; data units = GB per hour; LCU = max of these; cost = base + LCU x rate x 730
Because the unit is designed to represent overall capacity consumed. Charging the sum would double count a single connection that also transfers data.
Keep-alive and HTTP/2 reduce new connection rate, the usual dominant dimension. Serving static assets from a CDN reduces the data dimension.
