Zero: Financial Knowledge

• 34 interactive calculators — mortgage repayments and overpayments, offset and fixed-vs-tracker comparisons, stamp duty, ISA and investment growth, pension tax relief and the annual allowance, retirement drawdown, State Pension, Capital Gains Tax, Inheritance Tax, salary breakdown, emergency fund, Premium Bonds and more.

• A private daily finance tracker — log income, bills, transfers and accounts, see your tax and deductions, and keep a clear picture of where your money goes.

• Plain-English guidance — clear explanations on every calculator, so you learn as you go. No jargon, no assumptions.

• Made to fit you — a quick profile tailors figures to your age and situation; adjust text size, hide sensitive values at a glance, and switch between light and dark themes.
