Compound interest, real maths and why '15% a month' is a scam. The boring, reliable way to build wealth over time, with no get-rich-quick promises.

  1. 1

    Protecting is making

    Free●○○○○ difficulty

    Not losing money to interest, fees, scams and impulse buys is the first and safest 'return'. Your one action: find one leak this week (a forgotten subscription, a late fee, a card balance) and plug it.

  2. 2

    Pay yourself first

    Free with a code●○○○○ difficulty

    Save first, automatically, on payday, then spend what's left. Even a small amount builds the habit. Your one action: set up a standing order to a separate savings pot for the day after payday, even if it's £5.

  3. 3

    The boring order of operations

    Free with a code●●○○○ difficulty

    The boring order: priority bills, a starter buffer, clear expensive debt, take the employer pension match, full emergency fund, then long-term saving or investing. Your one action: write down which stage you're at today and the one next step in it.

  4. 4

    Compound interest: the real maths

    Free with a code●●○○○ difficulty

    Compound growth = growth on growth: amount × (1 + rate)^years. Compare savings using AER. Your one action: check the AER on your savings and work out what it would add to your balance in a year.

  5. 5

    The rule of 72

    Free with a code●●○○○ difficulty

    72 ÷ rate ≈ years to double. It works for savings, debt and inflation. Your one action: take the highest rate you pay or earn and work out its doubling time.

  6. 6

    Start at 22 vs start at 32

    Free with a code●●●○○ difficulty

    Time does the heavy lifting: ten extra years at the start can be worth more than decades of bigger payments later. Your one action: start a regular amount you can keep up, even £10 a month, rather than waiting for a 'proper' amount.

  7. 7

    Inflation vs your savings rate

    Free with a code●●●○○ difficulty

    Compare your savings rate with inflation: below it, your money buys less each year. Cash still suits emergency money. Your one action: check your savings rate against the latest inflation figure and see if a better easy-access or fixed rate would beat it.

  8. 8

    ISA, LISA, pension: the tax-free bubbles

    Free with a code●●●○○ difficulty

    ISAs, LISAs and pensions are tax-free wrappers, not investments. Pensions often come with employer money and tax relief. Your one action: check your payslip or pension account to see what you and your employer pay in each month.

  9. 9

    Index funds and the fee drag

    Free with a code●●●●○ difficulty

    Index funds aim to copy a market and are usually cheaper; fees compound against you every year. Compare the TOTAL cost: fund charge + platform fee + dealing fees. Your one action: if you have a pension or investments, find their total yearly charges in your latest statement.

  10. 10

    Risk, spreading and one meme coin

    Free with a code●●●●○ difficulty

    Higher possible returns come with higher risk. Spreading across many companies, industries and countries reduces the damage from any one failure, but can't remove risk. Your one action: if you hold investments, check whether they're spread out or riding on one thing.

  11. 11

    Time in the market, not timing it

    Free with a code●●●●○ difficulty

    Long-term money benefits from time, not timing. Regular amounts smooth your entry price, and panic selling locks in losses. Your one action: write one sentence on what your long-term money is for and when you'll need it, and read it next time markets wobble.

  12. 12

    The 15%-a-month maths

    Free with a code●●●●● difficulty

    15% a month compounds to about 5.35 times a year: £1,000 would pass £150,000 in 3 years. Nothing legitimate does that; it's a scam pattern. Your one action: when you see a monthly return promise, multiply it out (1 + rate) to the power 12 before you believe a word.

  13. 👑

    BOSS: Ronnie's Millionaire Masterclass

    Free with a code●●●●● difficulty

    Real wealth is boring: protect what you have, save automatically, compound over years, keep costs low, spread risk, and ignore anyone promising monthly miracles. Your one action: save the FCA register and Report Fraud (0300 123 2040) in your phone so you can check or report in a minute.

Build Wealth the Boring Way: quick answers

Mo owes £2,000 on a card at 25% APR and has £2,000 in savings earning 4%. Roughly what does keeping the debt cost him over a year, before the interest he earns?

About £500. Right: 25% of £2,000 is about £500 a year. Clearing it (while keeping a small buffer) 'earns' him that £500 back, with no market risk.
