About the Author — A Qualified Actuary Making Swiss Finance Simple
Hi, I’m Aga (Agnieszka) — a UK- and Poland-qualified actuary living in Zurich.
For over 15 years, I’ve worked in reserving, risk modelling, and financial structuring.
But behind all those formulas, what I really enjoy is explaining money in a way that genuinely helps in real life.
How It Started
When I moved to Switzerland, I was simply trying to find my footing — new role, new routines, and a financial system that took some decoding.
But the more I looked into our pension statements, tax deductions, and mortgage rules, the more I realised how complicated (and powerful) the Swiss system really is.
As an actuary, I couldn’t resist diving deeper — building spreadsheets, modelling tax outcomes, and testing “what-if” scenarios.
Soon friends began asking me to explain how health insurance, 3a accounts, or WEF withdrawals really work.
That’s how Actuary Explains was born — to turn that curiosity into something practical for others, not just for my own family and friends.
Twelve years later, my husband and I moved into our second Swiss home — a place big enough for our family of four. It’s the seventh property we’ve bought together, each one teaching us more about planning, trade-offs, and the value of long-term thinking.
Through this blog, I share those lessons along with the analytical tools that helped us turn financial dreams into structured, achievable goals.
What You’ll Find Here
I write about the systems that quietly shape your financial future — Swiss pensions (Pillars 1–3), home ownership, mortgage planning, investing, and tax optimisation — but I explain them in plain English, grounded in facts, not jargon.
Whether you’re a professional looking to optimise your taxes, an expat family working toward your first home, or simply curious about smarter ways to invest, my goal is to help you act confidently — not just read about finance.
My Journey
I earned my Master’s in Quantitative Methods in Economics and Information Systems at the Warsaw School of Economics and studied Financial Econometrics at the Norwegian School of Economics.
I also pursued Mathematics at the University of Warsaw — a mix that shaped how I think: rigorous in analysis, practical in application.
I’m a Fellow of the Institute and Faculty of Actuaries (FIA, UK) and a Polish Qualified Actuary (Licence No. 0248) — credentials built over more than 15 years across pensions, insurance, and investments.
Why I Write
I’ve always loved reading, writing, and exploring how things work — and yes, I’m a bit of a numbers nerd.
As an actuary, I’ve spent years analysing pensions, insurance, and investments — not just professionally but for my own family.
I realised that many people around me faced the same questions I once researched quietly in the background.
So I decided to share what I’ve learned — the logic, the strategy, and the small tweaks that can make a big difference — through this blog and later podcast.
Finance doesn’t have to feel distant or intimidating.
It can be something you truly understand — a tool to build freedom, security, and better choices for your family.
Actuary Explains is where I share that belief — through stories, models, and insights that make the Swiss system clear and actionable.
