Why do I undercharge?
The short answer
Undercharging can come from missing costs, unclear boundaries, or discomfort with asking for money. Start with the work and numbers before deciding the problem is your confidence.

Check the price you really receive
Look at a recent project. Include preparation, messages, revisions, and unpaid administration, not only the final task. Did you agree to extra work without discussing the price?
Compare the original agreement with what happened. If the work expanded, clearer limits may matter as much as a higher price. A deliberate discount is different from reducing your fee because silence feels uncomfortable.
Notice when the discount appears in the conversation: before a request, after a concern, or after the work has already expanded.
An imagined example
Imagine you quote for one written page, then include several meetings and unlimited edits. The client may think those are part of the offer. Defining the number of revisions would make the agreement clearer before you discuss another price.
Write the next offer differently
State what is included, what costs extra, and when payment is due. Practise saying the price without adding a discount immediately.
Use real costs and relevant market information when setting a fee. A chart cannot calculate the correct price or prove what a client will pay. It can help you reflect on the feelings that arise when you name your terms.
