Investing and trading calculators
Online calculators built for retail investors and traders — tools to support concrete financial decisions, not generic estimates.
FIRE calculator — financial independence and portfolio drawdown
The FIRE (Financial Independence, Retire Early) calculator runs in two modes. Path to FIRE projects how many years until you reach independence, complete with milestones, a cash-flow chart and the drawdown phase that follows.
Fund vs ETF fee calculator
A 25,000 EUR portfolio held in an active fund at 2% annual fees costs more than 50,000 EUR over 25 years versus the same money in an ETF at 0.2%. That isn't a typo — run the numbers yourself below.
DCF calculator — estimate a stock's intrinsic value
This DCF calculator estimates a stock's intrinsic (fair) value using the discounted-cash-flow method. Works for US equities (NYSE, NASDAQ), European exchanges and other international markets.
Compound interest calculator — projected investment growth
Project how your investment grows under the power of compounding. Enter the starting deposit, monthly contribution, expected annual return and time horizon — the result updates instantly in a chart and a year-by-year table.
What these calculators are for
Most investing and trading decisions come down to a calculation. What's a stock worth today if you project its future cash flows? How much do an active fund's fees actually cost you over 25 years? When can you realistically reach financial independence at your current savings rate? These calculators answer questions like that — simple form in, instant result out, with a chart you can read at a glance.
Each calculator comes with a written explainer and worked examples, so if the topic is new to you, the page walks through what the numbers mean and how to use them in your own decisions. Calculations on this page are for general information only — they're not investment advice.
