An actuary basically helps the team analyse data, build models, and keep the numbers accurate so the business can make smart decisions. The day-to-day depends on the team you’re in. In reserving, you’re looking at past claims data to estimate how much money the company needs to set aside for future claims. In reporting, you’re helping produce the regular financial reports, checking assumptions, and making sure everything ties up for auditors and regulators. In pricing, you’re helping work out how much products should cost by analysing risks and trends. And in capital modelling, you’re running models that test how the company would cope in different scenarios, like big financial shocks or extreme events. Whichever area you’re in, you’re mainly supporting the seniors, learning the software/tools, and gradually taking on more responsibility as you pass exams.
