Frequently asked questions
What is Button Counter?
Button Counter gives you a view of your financial future: how long your savings will last and what changes when you adjust something. You enter your age, your savings and what you want to spend each month. Button Counter then shows the chance that your money lasts until your end age, based on 4,000 simulations of good and bad market years.
Why Button Counter instead of a simple calculator?
A simple calculator answers one sum, such as how long an amount lasts or how much tax you pay on savings. Button Counter puts everything in one plan: your savings, your pension and state pension, work per period, one or two people and the rules of your country. Instead of one number you see the chance that your money is enough, based on 4,000 simulations. Every number shows whether it comes from a source, is an assumption or was entered by you.
How much savings do I need to stop working?
That depends on your monthly budget, your age and the pension you will receive. Button Counter calculates the amount you need for a 90% chance that your money is enough. As a rough rule of thumb, people often need 25 to 30 times the yearly spending that their pensions do not cover.
How is the chance of success calculated?
Button Counter runs 4,000 simulations in which returns go up and down each year. It does this for three portfolios (defensive, balanced and aggressive), after costs, tax and inflation, so every amount is in today’s money. The chance of success is the share of simulations in which your money lasts until your end age. Two crash scenarios, one like 2008 and one like 2022, are shown separately.
Which countries does Button Counter support?
Button Counter has its own rules for the Netherlands, Belgium, Germany, France, Spain, Italy, Portugal, Ireland, the United Kingdom and the United States, plus a general setting for other countries. Each country has its own state pension, pension age and tax on investments. Button Counter also compares what your budget is worth in 31 European countries, based on Eurostat price levels.
Is Button Counter free, and what happens to my data?
At the moment Button Counter is free to use, has no advertising and needs no account. What you enter stays in your own browser on your own device and is not sent to Button Counter. Visits and the use of features are counted anonymously, without cookies.
Is this financial advice?
No. Button Counter is a general calculation tool that gives estimates based on simplified rules and assumptions. It does not give advice about your personal situation. Check official sources and consult an independent, licensed adviser before you make important financial decisions.
