How to ask for a promotion?

TL;DR

To ask for a promotion, build the case before the conversation and show that you already work at the next level, not just that you work hard. Get clear on the business results you drive and be able to talk about them the way decision-makers do, then ask directly, opening the conversation by getting your manager talking about what the bigger role actually requires.

Insights

Doing your current job well is what got you here, but it is usually not what gets you promoted. The people who move up can show a higher level of business, strategic, and financial thinking. They understand how the company actually makes money, how their own work moves those numbers, and they can talk about it in those terms. Before you ask for a promotion, get specific about the results you drive and be ready to explain them the way a decision-maker would, because that is the level a bigger role is judged on.

When you have the conversation, do not lead with a list of demands. The stronger way to open is to get the other person talking first, so you understand what your manager and the team actually need. A simple and powerful opener is "Tell me": ask what a promotion would take, or what matters most to the team right now, and listen before you make your case. Then ask plainly for what you want. Asking well is mostly good questions and a clear request, not pressure.
