Our App is in the alpha stage, the beta is coming soon.

Welcome to Costs to Expect



Costs to Expect is a service focused on tracking and forecasting expenses. We are trying to simplify your budgets. There are three core products in the service; the Open Source REST API, our App and an Open Source website showing the costs to raise our children to adulthood.

Our API is the backbone of the service, everything depends on it. Our API is available to anyone who wants to use it. Our focus is expenses, however, that will change as the product matures.

The documentation for the API is available as a Postman collection.

  • We have added a JSON `data` field to resources. The `data` field can be used to store any optional data specific to your resource.
  • We have added additional tests.


  • We have updated our dev dependencies and switched to a new faker library.
  • We have moved the `Header` class to the `App\Response` namespace.
  • We have tweaked our `Option` classes; we no longer use the same data array to generate Post and Get responses.


  • We have corrected our resource-type and resources schemas; the required properties nesting is correct.


  • We have removed the `effective_date` field from resources; the new `data` field will take over responsibility for storing this data as necessary.
  • We have removed the `Response\Header\Headers` class; the class is mostly duplicated code and serves no purpose.
