How it works

Small amounts, given time, become big ones

This is the whole idea in one picture. The early years look quiet — and then the growth starts growing on itself.

Assumed growth a year:

Nobody knows what markets will do. Move the rate and see how much the answer changes — that uncertainty is the point. The guide works throughout at the cautious 5%.

Birth Age 18 Age 45 Age 70 £34.5k by 18 £436k by 70
£100 a month from birth to 18, then nothing more added — just left alone. Assumes 5% average growth a year

Illustrative only. Real returns go up and down, some years are negative, and nothing here is a forecast or a guarantee.

Sound familiar?

You want to do the right thing. Nobody explains how.

Most of us open an account, cross our fingers, and quietly wonder if we've picked the wrong one.

Why now

Starting early matters more than starting big

Same £100 a month. Same 18th birthday. One family begins at birth, the other waits until their child is 10. Each block is about £1,700.

£34,526
Started at birth
18 years of saving
£11,719
Started at 10
8 years of saving
Waiting ten years costs £22,806 — not because of the missed payments, but because of all the growth those payments never got to earn.

A peek inside

Every chapter ends with what actually matters

No hunting through pages for the point. Each part closes with a short "Key takeaways" box — like this one, straight from Part 1.

— From Part 1: Why investing early matters
KEY TAKEAWAYS
  • Investing aims to grow real value over time; cash on its own quietly loses ground to inflation.
  • Starting five years late doesn't just cost five years of money — it costs the growth those years would have earned.

Everything, for less than a family takeaway

Delivered straight away. Read it tonight, or on your phone at the school gates tomorrow.

An educational guide — not personal financial advice.
Good questions

Things people ask before buying

Is this financial advice?

No — it's an educational guide. It explains how each account works so you can decide with confidence, and it includes a full disclaimer.

I know nothing about investing. Will I follow it?

Yes. It's written in plain English, every term is explained the first time it appears, and there's a glossary at the back.

What do I actually receive?

A PDF guide of over 70 pages that you can read on any device or print, plus a Start Here sheet and the four bonus tools — PDFs and one Excel spreadsheet. Everything arrives as a single zip.

Won't the tax numbers go out of date?

Allowances do change at Budgets, so the guide flags every figure — and the separate allowances sheet is designed to be swapped each year.

My child isn't a baby — is it still useful?

Very much so. The guide is clear about how the right choice shifts as your child gets older.

Eighteen years sounds like a long time. It flies.

The earlier you start, the easier it is. Make this the week you stop putting it off.
