A Microsoft Azure Consumption Commitment (MACC) trades a multi-year spend pledge for discount tiers and credit flexibility. The discount is real — 8–35% depending on tier — but the trap is real too: Microsoft sellers are quota-credited on commitment size, so they push you to over-commit, and unconsumed commitment surrenders at term end. Size a MACC at 70–85% of your base-case forecast, keep growth on pay-as-you-go, and negotiate Marketplace credit eligibility. Here is exactly how.
A MACC is a contractual commitment to spend a set amount on Azure over a defined term — typically one, three, or five years — in exchange for improved consumption rates and credit flexibility. The discount scales with both commitment volume and term length: roughly 8–15% at the $1M tier, 15–30% at the $10M tier, and 25–35%+ at the largest enterprise tiers. The MACC is the base layer of Azure discount; reservations and Azure Hybrid Benefit stack on top of it. It is the first negotiation because it sets the rate against which every other layer is applied.
The non-obvious mechanic: a MACC is a floor, not a ceiling. You can spend above it on pay-as-you-go without penalty. You cannot spend below it without surrendering the shortfall. So the only sizing error that costs you money is committing too high — never too low.
This is a sub-guide in our Microsoft cost optimization pillar. It pairs with the Unified Support and Azure FinOps guides and sits under our Microsoft vendor practice. For the discount layers that stack on the MACC, see Inside Azure licensing.
Below are the discount tiers we benchmark against, plus the recommended commitment level for each. Note how the recommended commit level drops as the tier rises — larger commitments carry more surrender risk because growth forecasts at scale are less reliable, and the absolute dollars at stake are larger.
| MACC annual tier | Term | Typical discount vs list | Marketplace credit | Recommended commit |
|---|---|---|---|---|
| $1M+ | 1–3yr | 8–15% | Limited | 80–85% of base case |
| $5M+ | 3yr | 12–22% | Negotiable to 25% | 75–80% of base case |
| $10M+ | 3–5yr | 15–30% | Negotiable to 30–50% | 70–80% of base case |
| $50M+ | 5yr | 25–35%+ | Custom | 70–75% of base case |
The over-commitment trap is the single most expensive MACC error. Microsoft account teams have a structural incentive to size the commitment at the high end of your growth projections because the commitment scales their account quota credit. A customer who commits to 40% Azure growth over three years and delivers 20% reaches term end with a large unconsumed balance — and that balance surrenders. The discount you captured on the consumed portion rarely offsets the value you forfeited on the unconsumed portion.
| Scenario | 3yr commitment | Actual consumption | Discount captured | Surrender | Net outcome |
|---|---|---|---|---|---|
| Over-committed | $30M | $21M | ~$4.2M | $9M | Net loss vs PAYG |
| Right-sized | $21M | $24M | ~$4.0M | $0 | Full discount kept |
"The commitment-sizing question is the highest-leverage decision in the entire Azure negotiation — and the one Microsoft most wants you to get wrong."
We model your commitment against real consumption history and engineer the ramp. The sizing decision alone usually pays for the engagement many times over.
Credit flexibility turns "use it or lose it" into "use it somewhere useful." A negotiated MACC can allow a portion of committed spend — we have seen 30–50% at enterprise tiers — to be applied to Azure Marketplace listings and certain non-Azure Microsoft SKUs such as GitHub Enterprise. This matters because it gives you somewhere to drain unconsumed commitment before it surrenders. The clause is frequently left unaddressed by customers who focus only on the headline discount. Negotiate the eligibility breadth, the cap, and the timing of application — not just the percentage.
They are not alternatives; they are layers. The MACC sets the base rate. Reservations and Savings Plans discount specific workloads on top of the MACC rate. Pay-as-you-go covers everything above the commitment with no penalty. The optimal structure commits conservatively on the MACC, layers reservations on stable workloads, and lets variable and growth workloads ride PAYG. The detail of the reservation layer is in Azure Reservations & Savings Plans.
| Layer | Discount basis | Penalty if unused | Best for |
|---|---|---|---|
| MACC | Total Azure spend | Surrender | Base rate, all workloads |
| Reservations | Specific SKU/term | Forfeit hours | Stable, known SKUs |
| Savings Plans | Hourly compute spend | Forfeit unused | Variable compute |
| Pay-as-you-go | None | None | Growth headroom |

Start nine to twelve months before the commitment anniversary, because the consumption baseline Microsoft uses to anchor your next commitment is measured in the trailing months. If your FinOps cleanup has not happened by then, you are committing against inflated consumption. The strongest sequence is FinOps cleanup first, then MACC renegotiation against the clean baseline — the order we set out in the Azure FinOps guide and the complete Microsoft EA guide. Renew early and clean, and you negotiate against a number you control; renew late and dirty, and Microsoft negotiates against your waste.
For Azure commitments above $5M, independent advisory on the MACC sizing and ramp typically captures cost reduction equal to ten to twenty times the advisory fee — most of it from avoiding surrender, not from a bigger headline discount.
