Calculators
Simple, interactive tools to put the ideas from our lessons into practice — from compounding to your retirement number. Everything runs in your browser; nothing is stored or shared. Educational only, never financial advice.
Getting Started
See how an initial sum and regular contributions grow over time — and how much of the result is compounding rather than your own money.
Retirement & Wealth Building
Work out your financial-independence number and how many years until you reach it, based on your savings rate and expected returns.
Retirement & Wealth Building
Compare the same monthly take-home outlay routed to a pension (with tax relief and employer match) versus an ISA, and see which leaves you more to spend.
Risk Management
Size a position from your risk rules: choose how much of your account to risk and where your stop is, and see how many units that allows.
