Load Balancer Cost Calculator

Work out load balancer cost instantly with clear inputs, formula shown and shareable results.

About Load Balancer Cost Calculator

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.

Formula

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

Worked example

With the default values below, Load Balancer Cost Calculator returns Monthly load balancer cost of $162.43. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why is only the maximum dimension charged?

Because the unit is designed to represent overall capacity consumed. Charging the sum would double count a single connection that also transfers data.

How is load balancer cost reduced?

Keep-alive and HTTP/2 reduce new connection rate, the usual dominant dimension. Serving static assets from a CDN reduces the data dimension.
