Overview

Spend-based committed use discounts (CUD) provide a discount in exchange for your commitment to spend a minimum amount for a service or product. The discount applies to all of your vCPU and memory usage for the service.

The committed use discount dashboard provides a summary of your commitments, including region, cost, term, start and end dates, and trailing 30-day calculations for commitment cost, savings, utilization, and coverage.

The commitment analysis report helps you to visualize and understand the effectiveness and financial impact of the committed use discounts you have purchased.

Using the dashboard and analysis report, you can analyze your usage alongside your commitments to answer questions such as:

  • How much are my committed use discounts saving me on my bill?
  • Am I fully utilizing my existing commitments?
  • How much of my eligible usage is covered by commitments?
  • Is there an opportunity to save more by increasing my commitments?
  • Can I improve my commitment utilization by enabling discount sharing?

Viewing commitments

You can view a summary of all the committed use discounts you've purchased for your Cloud Billing account in the dashboard. To view a detailed analysis of a specific commitment, select it from the list of commitments in the dashboard.

  • Active commitment - The current quantity of commitments you have purchased for the given set of filters you select.
  • State - Identifies the state of the commitment as one of the following.

    • Creating - The commitment is being created.
    • Not yet active - The commitment has been created but is not yet active.
    • Active - The commitment is active.

      Spend-based commitments become active at the beginning of the next hour.

    • Expired - The commitment has expired.

  • Term - The term length of the commitment, such as 1 year or 3 years.

  • Start date - The year, month, and day that the comittment started.

  • End date - The year, month, and day that the comittment ends.

  • Recommendation - Estimated savings calculated by the CUD recommender.

  • Trailing 30-day commitment cost - The cost of ownership of a commitment, independent of your usage.

  • Trailing 30-day savings - The net savings from the commitments based on the last 30 days of usage. Total committed use discounts (credits) applied to eligible on-demand usage minus the cost of the commitment fee.

  • Trailing 30-day utilization - The percentage of available committed use discounts that were applied to eligible on-demand usage.

  • Trailing 30-day coverage - The percentage of eligible usage whose effective cost was reduced by your commitment.

You can also purchase commitments from the committed use discount dashboard. To purchase a new commitment while viewing the dashboard select Purchase.

Understanding the analysis report

The committed use discount analysis page shows the details of the selected commitment for the period specified in the filter, including summary cards, a stacked bar chart, and a summary table of the commitment's totals.

Summary table

The summary table appears below the stacked bar chart, at the bottom of the analysis page, displaying aggregate quantities and hourly averages for the time range being shown.

Understanding your bill

Google Cloud uses a balance sheet format for your bill:

  1. You are billed a commitment fee, which is the discounted cost of your covered usage. You are billed this fee on a recurring basis, regardless of your usage.
  2. You are billed for the standard on-demand costs for resources that you consume.
  3. You receive committed use discount credits that appear in your bill as negative costs. These offset the portion of your eligible on-demand charges covered by the commitment.

The net impact of these three components is that you receive a discount on the usage covered by your commitment. The sum of your commitment fee (1) and committed use discount credits (3) equals the savings from your committed use discounts.

Example of usage equaling commitment

This example shows a Cloud Billing account where the spend-based committed use discount equals the usage for the one-hour period.

You purchase a one-year commitment for $50/hour of on-demand spend on Cloud SQL databases in the us-central-1 region. This one-year commitment gives you a 25% discount on covered usage, resulting in your net cost being $37.50/hour.

  1. You are charged a $37.50 commitment fee.
  2. You are charged $50 of on-demand costs for the one hour.
  3. You receive $50 in credit that offsets your $50 of on-demand costs.

Total costs = $37.50 + $50 - $50 = $37.50

In this example, your committed use discount covers all of your usage and there is no overage. Your final cost for the hour is $37.50 with the committed use discount. Without the discount, the total cost for the hour would have been $50.

Example of using more than commitment

This example shows a Cloud Billing account where the actual usage is more than the spend-based committed use discounts purchased. This results in an overage, where you pay the on-demand rate for the amount beyond your commitment.

You purchase a one-year commitment for $40/hour of on-demand spend on Cloud SQL databases in the us-central-1 region. This one-year commitment gives you a 25% discount on covered usage, resulting in your net cost being $30/hour.

  1. You are charged a $30 commitment fee.
  2. You are charged $50 of on-demand costs for the one hour.
  3. You receive $40 in credit that offsets your $40 of on-demand costs.

Total costs = $30 + $50 - $40 = $40

In this example, your committed use discount covers some of your usage. You paid $10 in overage at the on-demand rates and received a 25% discount on the $40 of on-demand equivalent costs covered by your commitment. Your final cost for the hour is $40 with the committed use discount. Without the discount, the total cost for the hour would have been $50.

Example of using less than commitment

This example shows a Cloud Billing account where the actual usage is less than the spend-based committed use discounts purchased. This results in an unused portion of the commitment.

You purchase a one-year commitment for $60/hour of on-demand spend on Cloud SQL databases in the us-central-1 region. This one-year commitment gives you a 25% discount on covered usage, resulting in your net cost being $45/hour.

  1. You are charged a $45 commitment fee.
  2. You are charged $50 of on-demand costs for the one hour.
  3. You receive $50 in credit that offsets your $50 of on-demand costs.

Total costs = $45 + $50 - $50 = $45

In this example, your committed use discount covers all of your usage and there was no overage. However, you committed to $60 of on-demand equivalent spend and only spent $50, failing to use the last $10 of credit paid for. Your final cost for the hour is $45 with the committed use discount. Without the discount, the total cost for the hour would have been $50.

Understanding your invoice or statement

You can view all three components of the spend-based committed use discount on your invoice or statement.

  • Commitment fee - The SKU description begins with Commitment - dollar based. For example, the commitment fee for a Cloud SQL CUD in the us-central-1 region for 3 years would appear as Commitment - dollar based v1: Cloud SQL database in us-central1 for 3 years.
  • On-demand costs - Charges for your usage at the on-demand equivalent cost. For example, Postgres DB custom CORE running in Americas.
  • Credits - These offset the portion of your on-demand equivalent costs that are covered by your committed use discount.

Understanding your Cloud Billing reports

Cloud Billing reports let you view your Google Cloud usage costs and credits to discover and analyze trends. The Cloud Billing reports provide a variety of user-configurable options to view the costs that are important to you, including options to view your credits.

To view the individual components that comprise your committed use discounts, group your costs by SKU. The default report view (not grouped by SKU) does not break out the CUD components but instead includes the net of the three components.

To view only your ongoing commitment fees, limit the report results to the relevant commitment fee SKUs using the SKUs filter. For example, select the SKUs filter and type Commitment [YOUR COMMITMENT TYPE].

To understand how your commitment fees and credits are applied to your Cloud Billing account and projects, see Attribution of committed use discount fees and credits.

Viewing CUD fees and credits in your data exports

If you are exporting your Cloud Billing data to BigQuery, you can use queries to analyze the data.

For examples of how you might use BigQuery queries to view your commitment fees and credits in your Cloud Billing data exports, see Committed use discount queries.

Viewing commitments in your local currency

If you have a billing account in your local currency, you can view information about the discounts you've purchased by accessing the committed use discount dashboard and the committed analysis page.

To view your active and expired Trailing 30-day commitment costs, Trailing 30-day savings, Trailing 30-day utilization, and Trailing 30-day coverage, use the committed use discount dashboard. You can view your active commitments in your local currency and USD.

You can view savings, analysis chart details, commitment covered costs, and eligible costs not covered in your local currency with the committed analysis page.
