Box Theory —
the curriculum

Five interactive guides covering the foundational knowledge behind the Money Lifemap framework. Free to use, no login required. Built to be read, explored, and returned to — not printed and filed.

These guides are interactive HTML tools — they include calculators, sliders, scenario panels, and live illustrations that only work in a browser. This is intentional: the interactivity is the learning. All guides open in a new tab.

The learning arc

How the five guides build on each other

Step 1

Where to put it

Tax wrappers, ISAs, pensions, GIAs — the containers and their rules

Step 2

What to put in it

Investment construction, diversification, risk, cost, active vs passive

Step 3

Will it last?

Decumulation, withdrawal rates, risk of ruin, sequence-of-returns

Step 4

How to model it

Cash flow modelling, lifetime planning, assumptions, scenarios

Step 5

What kind of support do I need?

Self-direction vs guided session — understanding where you are

The guides can be read in any order, but the sequence above reflects the natural progression — from the mechanics of where money sits, through how it grows, through whether it lasts, to how to model it and finally how to decide what support is right for you.

Box Theory · Guide 1 of 3

The Box Theory

Introduces the concept of tax-efficient wrappers — ISAs, pensions, and general investment accounts — and explains why the container matters as much as its contents. Covers the Box Complexity Measure (BCM™) as a framework for understanding how complex your existing tax wrapper position is.

Box Theory · Guide 2 of 3

What Goes in the Box?

Moves inside the wrapper to explore investment construction principles. The guide begins with the insight your grandmother probably already knew — don't put all your eggs in one basket — and builds from there through diversification, asset classes, correlation, the impact of costs, and the active vs passive debate. Includes live interactive calculators.

Box Theory · Guide 3 of 3

Will It Last?

Addresses the shift from accumulation to decumulation — where the planning questions change fundamentally. Introduces risk of ruin, sustainable withdrawal rates, and the sequence-of-returns effect. Asks the question nobody asks until it's too late: not how much will I have, but will it be enough, for long enough? Includes live risk-of-ruin modelling.

Planning framework

The Cash Flow Framework

How cash flow modelling works and how to read a lifetime model

Explains the mechanics and purpose of cash flow modelling as a planning tool — how a lifetime model is constructed, what the key assumptions are, how to read and interpret the output, and how scenario analysis helps explore decisions without making them for you. Foundation reading before a guided session.

Guidance framework

Door A or Door B?

Understanding whether self-direction or guided support is right for you

Helps you think through where you are in your financial education journey and what kind of support is most useful right now. Door A is self-directed — using the free tools independently to build knowledge at your own pace. Door B is guided — working with an educator when your situation has complexity that benefits from structured support.

Self-direction Guidance need Activation level Where to start

Want to go deeper than the guides?

The guided Money Lifemap session uses the full cash flow modelling suite alongside an educator — working through your own figures, your own scenarios, with a second brain alongside you. The guides are the preparation; the session is where it comes to life.
