 When you purchase a Savings Plan, you:
 
-- Commit to a specific amount of resource usage each month, calculated before taxes and discounts. This is the usage amount you will be billed for at the Savings Plan rate.
-- Will be charged at the Savings Plan's discounted rate for any usage within your committed amount.

-      This means that:
-        - If you use less than what you committed to, you will still be billed for the committed amount with the Savings Plan discount applied.
-        - If you use more than the committed amount, the extra usage will be charged at the regular on-demand rate.

 <Lightbox src="scaleway-savings-plan.webp" size="medium" alt="the image contains a graph showing a simulation of how the Savings Plan works for an account. X axis = month and Y axis = commitment amount in Euro. A horizontal line represents the committed amount. The graph displays the consumption of an account over three months. In the first month, the consumption is under the committed amount, so under the line. For the second month, the consumption is exactly the committed amount, so it joins the line. On the third and last month, the consumption went over the committed amount. Therefore, it goes over the line." />
 
+### Example
+
+If you have Savings Plan with a committed amount of 900€ per month, a 10% discount is applied. You consumption within the Savings Plan will cost you 810€ per month.
+
+If in the month of March, you use:
+
+| Number of Instances | Instance Type         | Hourly Price | Usage (in hours)  | Monthly total |
+| ------------ | ------------------- | ------ | ------ |------ |
+| 1        | DEV-1S |  0.008€   | 744  | 5.95€ |
+| 1    | POP2-64C-256G      | 2.35€ | 381 | 895.35€ |
+|   |  |      | **Total**  | 901.30€ |
+
+Since the Savings Plan has a committed amount of 900€, you would be charged:
+
+**810€** (the discounted monthly fee for the committed amount) **+** **1.03€** (the excess amount used above the committed amount, charged at the standard price) **=** **811.03€**.
+
+This means your total bill for March would be **811.03€**.
