Editing ROI Calculator

Use this easy-to-use editing ROI calculator to learn how much you can save per year by using EditorNinja instead of hiring editors on your own. You will also learn how much extra revenue you are currently leaving on the table by editing in-house or having writers edit the work of others.

Of course, a common use case for EditorNinja is when an editor quits and you still need editing done. We can get started the day you join EditorNinja. Schedule a free editorial assessment here.
