Key Takeaways

What every buyer should know about Broadcom per core billing.

  • 16 cores per CPU minimum. Low core hosts overpay.
  • Fragmentation multiplies the penalty. Many small hosts cost more.
  • Consolidation is the biggest lever. Cut billed cores first.
  • Rate matters second. A low rate on bloated cores still overpays.
  • Right size before the term. Multi year locks the core count.
  • Quantify the floor penalty. Then act on it.
  • Directional only. Negotiate the real rate.

Broadcom prices VMware per core with a minimum of 16 cores per CPU. Hosts with fewer than 16 cores per CPU still bill 16, so fragmented estates pay a floor penalty on cores they do not have.

Quantify the penalty, then consolidate against it.

Quick answer

Broadcom bills VMware per core with a 16 core per CPU minimum, so a CPU with fewer than 16 physical cores still bills 16. Example: 2 CPUs at 10 physical cores bill 32 cores, a 12 core floor penalty per host. See VMware per core licensing and Broadcom VMware.

Per core subscription estimator

What drives the per core subscription cost?

Broadcom bills VMware per core with a 16 core per CPU minimum, so a CPU with fewer than 16 physical cores still bills 16.

The 16 core floor

Each CPU bills a minimum of 16 cores. A 10 core CPU bills 16, so six cores are pure floor penalty per socket.

Host fragmentation

Many small hosts multiply the floor penalty. Consolidating onto fewer, denser hosts cuts the billed core count.

The negotiated rate

The per core rate is set by volume and term. A lower rate on a bloated core count still overpays, so fix the cores first.

Right sizing the estate

Retiring idle hosts and consolidating workloads is the largest lever, ahead of the rate negotiation.

Term and true up

Multi year terms lock the rate but also the core count. Right size before you commit the term.

Where the common advice on Broadcom per core billing is wrong

The standard advice is to negotiate the per core rate down and accept the core count. We disagree. The rate matters, but the 16 core floor on fragmented estates is the bigger leak. The buyer side move is to consolidate low core hosts and retire idle ones to cut the billed core count first, then negotiate the rate on the reduced base.

The first Broadcom renewal is not a discount conversation. It is a leverage conversation. Build a credible exit path twelve months out and the per core quote reshapes itself.

Seven leverage points on every Broadcom VMware contract

  1. Score renewal risk twelve months before the term ends. Not when the quote lands.
  2. Model the per core math including the 16 core minimum. Know the real billable count.
  3. Consolidate workloads onto denser hosts before renewal. Cut wasted cores.
  4. Match the bundle to your workload mix. VCF and VVF are not interchangeable.
  5. Build a credible exit path to Nutanix, Proxmox, or Azure. Leverage needs an alternative.
  6. Cap the multi year uplift at signing. Broadcom defaults to steep annual increases.
  7. Never share calculator output with your Broadcom account team. Buyer side data only.

What to do next

  1. Run the Broadcom renewal risk assessment as the first pass.
  2. Run the VMware licensing calculator to model per core cost.
  3. Run the VCF migration cost estimator if a VCF move is in scope.
  4. Pull your host inventory and physical core counts per CPU for the whole estate.
  5. Score readiness with the renewal readiness assessment.
  6. Price the exit path to Nutanix, Proxmox, or Azure before the renewal call.
  7. Engage independent buyer side advisory if VMware spend is over $500K annually.

Frequently asked questions

How does Broadcom per core billing work?

Broadcom prices VMware per core with a minimum of 16 cores per CPU. A CPU with fewer than 16 physical cores still bills 16 cores.

What is the core floor penalty?

It is the gap between physical cores and billed cores caused by the 16 core minimum. A 10 core CPU bills 16, so six cores per socket are floor penalty.

How do we cut the penalty?

Consolidate workloads onto fewer, denser hosts and retire idle hosts. Fewer CPUs at 16 plus cores means less wasted floor.

How accurate is the calculator?

It is directional, applying the 16 core floor to your CPU and core inputs. Your negotiated rate sets the final cost.

Should we negotiate the rate or the cores first?

Cores first. A lower rate on an inflated core count still overpays. Right size the estate, then negotiate the rate on the reduced base.

Is the calculator free?

Yes. It is free and runs in your browser. No payment and no account required.

Should we share the output with Broadcom?

No. It is buyer side data. Build the position internally and negotiate on your modeled core count.

How does Redress engage on Broadcom per core?

We model the floor penalty, plan the consolidation, benchmark the rate against our deal database, and sit at the table for the renewal. We are not a Broadcom partner.
