# Running your Savings Estimate
**Step 1:** Visit the Pump Dashboard.
**Step 2:** Click Finish Step 1 or Self-serve
**Step 3:** Click Connect AWS
**Step 4:** Create a Read Only Cloud Stack Formation (we only take permissions to see your past cost data and predict how much we could save you!)
Here are the permissions we ask for to calculate a savings estimate (we don't have permission to make any changes, these are just **read/get permissions.**

In 60 seconds or so, you can see your savings estimate on what we can realistically save you (independent of your past Reserved Instance and Savings Plan purchases). We calculate this based on your current Cloud Spend usage and estimate how much you could save further with Pump's model **for free**.
