Simple Investing

Your needs change over the course of life, but the underlying method stays the same: get your situation in order, choose a strategy that's simple to understand and stick with, and know the right tools to put it into practice. This course follows exactly that path, in three modules.

Module 1 — The Basics

Before talking about investing, let's get your personal situation in order: net worth, budget, savings and an emergency fund. There's nothing to buy in this module — only to put in order, one pillar at a time.

Net worth

Net worth is Assets − Liabilities = Net worth: the real snapshot of your financial solidity, what you own minus what you owe. Knowing it lets you see how much of your wealth is truly liquid — quickly available if needed — and whether the mix between property, financial investments and cash is balanced against your goals. A general principle: when a single category — property, financial assets or cash — exceeds 75-80% of total net worth, it's worth asking whether that concentration is a conscious choice or simply the result of how the wealth built up over time.

The budget

You can't improve what you don't measure. A budget lets you know precisely what comes in, what goes out, and above all what's left each month. The secret isn't giving up every pleasure, but making every pound spent visible. A useful starting rule is 60/20/20: 60% essential spending, 20% non-essential spending, 20% saving — a starting point, not a fixed rule: adapt it to your income level and a sustainable lifestyle.

Save before you invest

The golden rule: aim to save at least 20% of your net income. If that's not realistic today, start at 5% and increase it every time expenses fall or income rises — the starting figure doesn't matter, consistency does. Some useful questions to find room: is that expense a real need or a passing want? Are there contracts (utilities, insurance, subscriptions) you haven't renegotiated in years? It's best to avoid large purchases on credit: interest charges quietly erode savings.

The emergency fund

Why invest: your goals

Needs change over the course of life, and each goal calls for a different approach. Four broad goals come up most often:

Beyond these broad goals, there are concrete milestones that deserve their own plan: buying a home (a defined horizon and cautious risk management), travel and personal projects (a dedicated fund, without touching your main portfolio), boosting your pension with a supplementary pot, and your children's education — university, a master's or time abroad — by investing from an early age.

Time works for you

An investment's gains generate further gains in turn, year after year — compound interest. At an average annual return of 10%, in line with the long-run historical average of a global equity portfolio, £10,000 invested and never touched becomes roughly £25,900 after 10 years, £67,300 after 20 years, £174,500 after 30 years and £452,600 after 40 years. Past performance doesn't guarantee future results — this is an illustrative example based on the long-run historical average.

What ETFs are

For decades, building a diversified portfolio was only possible through funds run by banks — expensive and opaque. An ETF (Exchange Traded Fund) is a basket of securities bought on an exchange exactly like a single share. An ETF on the MSCI World means investing in over 1,400 companies across 23 developed countries at once, for an annual cost of just 0.10-0.20% — against 1.5-3% or more (up to 10-15 times as much) for traditional funds.

The most common alternatives in the UK

In the UK, the average saver is often steered towards products offered by their own bank or a traditional wealth manager. An honest assessment of the main ones:

Workplace/personal pension (SIPP): contributions get tax relief, up to annual allowance limits — a real tax advantage. The money is locked away until at least age 55 (rising to 57), though — complementary, not a substitute, worth discussing with a qualified adviser.

Module 2 — The Strategy

How the Global Equities + Cash strategy works in detail: why it was chosen, how it adapts to you, and how to manage it over time.

Your financial journey

The same strategy adapts, simply by changing the proportions, to every stage of life:

The percentages by age band are indicative, not a fixed rule: your ideal allocation also depends on your personal risk tolerance, not just your age.

Why this strategy — and not another

Many valid investment strategies exist. Here's why SimpleInvest didn't choose the more common alternatives — none of them is wrong, but for a beginner, understanding one thing well beats understanding four things poorly:

• MSCI World + Bonds (60/40): a tried-and-tested classic, but it requires familiarity with concepts like duration and interest-rate risk.
• MSCI ACWI (including emerging markets): broader geographic coverage in one instrument, but with higher volatility and greater geopolitical and currency risk.
• Multi-asset ETFs (e.g. Vanguard LifeStrategy): automatic rebalancing included, but less flexibility — no adjustable percentages or a separate Cash buffer.
• Actively managed funds (the ones your bank sells): charges of 1.5% to 3% or more, against 0.10-0.20% for a passive ETF — over 20-30 years, the difference can amount to tens of thousands of pounds.

Who it suits

How much Equities and how much Cash

The shorter the horizon, the less time there is to recover from a downturn. The largest historical crises (MSCI World: 2008 roughly -54%, 2020 roughly -34%, 2022 roughly -25%) took up to 3-5 years for a full recovery.

Initial capital and recurring contributions

Even a modest initial amount makes a huge difference over the long run thanks to compounding: the best time to start is as soon as possible. Anyone dealing with a significant lump sum — from a property sale or an inheritance — faces a different challenge: investing it all at once risks entering the market at its peak. Two prudent approaches: spread the purchases over 12-24 months, or start with a lower equity share (e.g. 40-50%) and increase it gradually.

For recurring contributions, use pound-cost averaging: each month or quarter, buy a fixed amount of a World ETF regardless of the market price — this automatically buys more units when prices fall and fewer when they rise, lowering your average purchase price over time. You don't need a large starting sum: even £100-200 a month, invested consistently for 20-30 years, produces meaningful results.

Income and decumulation

When you reach your goal — retirement, financial independence, a supplementary income — the same strategy supports a gradual drawdown. Rather than cashing out everything at once, you withdraw a share periodically while leaving the rest invested. The Cash component acts as a buffer: you draw from it first, letting the equities keep working. A common rule of thumb is an annual withdrawal of 3-4% of the total portfolio — at that level, a portfolio has historically held its real value over time.

Rebalancing: when and how

Every 3 or 6 months, the portfolio is brought back to its target mix: if equities have grown a lot, some are sold; if they've fallen, more is bought with the available cash. Typical thresholds, ideally asymmetric: buy below target at −5%, sell above target at +10% — designed to lower the average purchase price and take advantage of rallies. There's no need to predict the market: the point is keeping risk under control over time, with a rule decided in advance, not in the panic of the moment.

When the market falls: the checklist

1. Follow your rebalancing rules — buying below the target threshold, selling above it: the automatic mechanism that takes advantage of downturns without guessing the right moment.
2. If you can, inject fresh capital during downturns — buying at lower prices amplifies future returns.
3. Only revisit your Equities/Cash split if the downturn threatens your short-term goals — never as a last-minute reaction to panic.
4. If you're drawing an income, consider reducing it temporarily — withdrawing less during a downturn leaves more capital invested to take part in the recovery.
5. Use the Cash component as a buffer for your monthly income, instead of selling equities at a loss.

In short, the strategy forms a continuous cycle: initial capital and recurring contributions flow into the portfolio, split between Global Equities (the growth engine) and Cash (the interest-bearing buffer), periodic rebalancing keeps the target weights in check, withdrawals or income come out of both components, and the portfolio evolves over time through market cycles.

Module 3 — ETFs

The concrete tools: what they are in detail, which ones to choose, and where to buy them, with reference to the London Stock Exchange.

ETFs: the essential fact sheet

An ETF that tracks the MSCI World index is the recommended starting instrument. Generally domiciled in Ireland or Luxembourg, they're listed on the main European exchanges: London, Euronext, Xetra, Milan, Madrid.

• TER — the fund's total annual cost. Lower is better, for the same index tracked.
• AUM — the assets the fund manages. A stability indicator: larger funds tend to last longer.
• Acc (accumulating) — dividends are automatically reinvested into the fund.
• Dist (distributing) — dividends are paid out to you periodically.

To start, the accumulating (Acc) version is generally the simplest and the most tax-efficient over the long run inside an ISA.

MSCI World: the real tickers (London Stock Exchange)

All four can be held inside a Stocks & Shares ISA. Always check the up-to-date figures (TER, AUM, ISIN) on the provider's site before investing — values can change over time.

The Cash component: SONIA ETFs

For the Cash part of the strategy, sterling money-market ETFs are used that track SONIA (the Bank of England's overnight rate) — a liquid, interest-bearing alternative to a plain savings account.

Distributions from this ETF are treated as interest for UK tax purposes, not as dividends — inside an ISA they're tax-free either way.
