Heroku prorates all costs to the second. The price per database/month is the maximum you're charged if your database stays provisioned 24 hours a day, 7 days a week since your last billing cycle.
Before the ending of our free plans on November 28, 2022, we will introduce our new Mini data plans:
- The Mini Heroku Postgres plan for $5/month.
- The Mini Heroku Data for Redis plan for $3/month.
For example, if you create a Mini Postgres database and delete it after 15 days, it will cost you roughly $2.50.
Learn more about our Eco and Mini plans here.
Currently, our cheapest plans are:
The Hobby Basic plan for Heroku Postgres is available for $9/month.
The Premium-0 plan for Heroku Data for Redis is available for $15/month.
For example, if you create a Hobby Basic Postgres database and delete it after 15 days, it will cost you roughly $4.50.
