Your discounts won't change after migration, because your current contractual rates are guaranteed for the duration of your contract. As long as your usage remains the same, your total costs won't increase. To see how your billing and discounts will look after the migration, you can use the BigQuery Sample Data Export. To understand your savings, commitment utilization, and effective savings rate, you can use the Compute flexible CUD example queries. To view your discount percentages before migration (old CUD model) or after migration (new CUD model), choose one of the following steps.

- To view your effective CUD discount compared to List On-Demand Price, see Calculate your overall flexible CUDs savings.

After you migrate to the new model, SKUs can have different usage rates based on the consumption model you use them under.
In the following example, we analyze the SKU named N2 Instance Core running in
Americas (SKU ID: BB77-5FDA-69D9). This SKU has three primary consumption
models:
- On-Demand: Standard, pay-as-you-go usage (consumption model
7754-699E-0EBF). - 1-Year Flexible CUD: Usage covered by a 1-year commitment
(consumption model
D97B-0795-975B). - 3-Year Flexible CUD: Usage covered by a 3-year commitment
(consumption model
70D7-D1AB-12A4).
Use the Pricing user interface to see details about the pricing for each model:
In the Google Cloud console, go to your Cloud Billing account.
[Go to your Cloud Billing account](https://console.cloud.google.com/billing){: target="console" track-type="tutorial" track-name="consoleLink" track-metadata-position="body" class="button button-primary" }Select Pricing from the sidebar.
Both the public list price and your contractual prices are displayed.
In this example, we add two columns to show the savings ($/%) compared to the on-demand consumption model.
| Fields from pricing UI | Added fields to show savings calculations | ||||||
|---|---|---|---|---|---|---|---|
| SKU ID | Consumption model ID | Consumption model description | List price ($) | Contract price ($) | Effective discount (consumption model list vs contract) |

The preceding chart uses five formulas to calculate the dollar savings in the columns named Savings from on-demand contract rates and Savings from on-demand list rates.
The calculations use the formula New Price - Baseline Price to show savings
as a negative value. The accompanying percentage is then calculated by dividing
that dollar saving by the baseline price.
Savings from on-demand list rates (for on-demand usage)
This formula calculates your initial savings from using the discounted On-demand Contract Price instead of the public On-demand List Price.
Formula: On-demand Contract Price − On-demand List Price
Example from chart: $0.02055 − $0.03161 = −$0.01106
Savings from on-demand contract rates (for 3-Year CUD)
This formula calculates the additional savings gained by using a 3-Year Flexible CUD compared to the already discounted On-demand Contract Price.
Formula: 3-Year CUD Contract Price − On-demand Contract Price
Example from chart: $0.01408 − $0.02055 = −$0.00647
Savings from on-demand list rates (for 3-Year CUD)
This formula calculates the total savings gained by using a 3-Year Flexible CUD compared to the public On-demand List Price.
Formula: 3-Year CUD Contract Price − On-demand List Price
Example from chart: $0.01408 − $0.03161 = −$0.01753
Savings from on-demand contract rates (for 1-Year CUD)
This formula calculates the additional savings gained by using a 1-Year Flexible CUD compared to the on-demand Contract Price.
Formula: 1-Year CUD Contract Price − On-demand Contract Price
Example from chart: $0.01878 − $0.02055 = −$0.00177
Savings from on-demand list rates (for 1-Year CUD)
This formula calculates the total savings gained by using a 1-Year Flexible CUD compared to the public On-demand List Price.
Formula: 1-Year CUD Contract Price − On-demand List Price
Example from chart: $0.01878 − $0.03161 = −$0.01283
Calculate the effective savings rate (ROI)
To calculate your effective savings rate (ROI), use the CUD KPI sample queries. Separate sample queries are available specifically for the legacy data model and the new data model to facilitate comparison.
