Most people pick investing as their starting point. They open a Stocks and Shares ISA before they have an emergency fund, before they have a budget, sometimes before they have a clear picture of what they owe. The sequence matters. Skip a step and you often end up undoing work later.
Before you move money anywhere, know three figures: what comes in each month after tax; what goes out in fixed costs (rent, mortgage, bills, subscriptions); and what's left. That gap is your working material. Everything else is built on it.
A small cash buffer of £500 to £1,000 sits in your current account and absorbs emergencies without derailing everything else. A broken boiler shouldn't go on a credit card if you can avoid it. Once that's in place, attack expensive debt. Credit cards at 20% APR cost you more than almost any investment earns. Pay them down before putting money into markets.
Three to six months of essential expenses in an easy-access savings account. This takes time and feels slow, but it's what makes everything else sustainable. People with emergency funds don't panic-sell their investments when the unexpected hits.
A 20% savings rate means most people can reach financial independence within 20 to 30 years. At 10%, it takes closer to 40. The order exists for a reason.
Before the question becomes "what do I invest in?", the more important question is "how much can I invest?" Most people find they can save more than they thought, once they can see their numbers clearly. A 20% savings rate is the target worth working toward.
Once the groundwork is there, investing becomes straightforward. Regular contributions into a low-cost diversified fund inside an ISA or pension. Time in the market matters more than timing the market.
The order exists for a reason. Investing on top of expensive debt or without an emergency fund leaves you vulnerable in ways that cancel out any returns.
