If you've already submitted your application, there's not much you can do anyway except wait.
Here at Travel.SE we semi-regularly see questions from people in your situation who are confused by those parts of the application, so we can probably assume that ECOs are also familiar with the common ways to misunderstand them. If the numbers are clear enough that they can make sense of your application at all, it is unlikely that they'll refuse you solely for a bureaucratic mistake.
If they can't make sense of your numbers, you might get a refusal saying in essence "these numbers don't make sense to me". At least for the UK you'll get an individually written letter that tells you exactly what they didn't like in the application. (Some other countries reject with pithy form letters where you have to engage in a lot of guesswork). You can then immediately reapply with a clearer explanation.
