Monitoring Google Maps Costs
Google provides a free monthly usage allowance for all Maps APIs, and for most stores it's more than enough — you'd need tens of thousands of map loads or address searches per month before any charges kick in. That said, it's worth setting up a billing alert so you get an email if your usage ever unexpectedly crosses that threshold.
Note: In March 2025, Google updated its Maps Platform pricing. The free tier allowances referenced in this article reflect the current pricing as of that update. For a full breakdown, see Google Maps Licensing Explained.
What Is a Billing Alert?
A billing alert sends you an email when your Google Maps spending reaches a limit you define. Since the free tier effectively means $0 in charges, setting a $1 alert is a reliable early warning — if you ever receive that email, it means something unusual is happening with your map usage and it's worth investigating.
Note that billing alerts track usage after the fact — they notify you once a threshold has been crossed, but don't prevent it from happening. If you'd prefer a hard limit that cuts off usage automatically, see Setting Up Quotas to Limit Google Maps Usage instead.
Set Up a Billing Alert
1. Log into the correct Google account.
Make sure you're signed into the same account you used when setting up your Google Maps API key. You can verify this on the Google Account page.
2. Open the Google Cloud Billing page.
Go to Google Maps Billing Page.
3. Select your billing account.
Click on the name of the billing account you linked to your Google Maps key. If you haven't set up a billing account yet, you'll need to do that first before continuing.
4. Create a new budget.
In the left sidebar, click Budgets & alerts, then click Create budget.
5. Name your budget and configure the scope.
On the Scope screen, give the budget a name you'll recognize — something like "Store Locator Map Usage" works well. Make sure both Credits checkboxes are unchecked, then click Next.
Unchecking the Credits boxes ensures the alert reflects your actual billable usage, not usage offset by any Google promotional credits you may have received.
6. Set the budget amount.
On the Amount screen, enter $1 as your budget. This means you'll be notified as soon as your spending exceeds the free tier. Click Next.
7. Simplify the alert thresholds.
On the Actions screen, you'll see three default thresholds (50%, 90%, 100%). Delete the first two so that only the 100% threshold remains. This way you get a single clear notification rather than multiple emails as usage climbs.
8. Save the alert.
Click Finish. Your billing alert is now active.
Once set up, you'll receive an email if your Google Maps usage ever exceeds the free tier. You can return to the Budgets & alerts page at any time to check your current usage level or adjust the alert settings.
Billing alerts monitor your usage but don't cap it. To set hard limits that automatically stop requests once a daily threshold is reached, consider setting up service quotas.
