Ask most managers about the hardest part of stepping up, and money comes up fast. One day they’re running a team and delivering work. The next, they’re handed a budget and expected to plan it, defend it and answer for it, often with no training in any of it. It comes down to a set of financial management skills that most managers were never taught, and that gap is far more common than you’d think.
The quiet cost of financial guesswork
When a manager doesn’t understand the numbers, the effects are rarely dramatic. There’s no single moment where it all goes wrong. Instead, it shows up slowly, in overspends that surprise everyone, in budgets padded out of caution, in good ideas that never get funded because no one could make the case for them. Poor management and leadership practices cost UK businesses an estimated £84bn a year (CMI / Coutts, 2024), and weak financial decisions are part of that picture. A manager guessing at their numbers is making decisions with one hand tied behind their back.
What financial management skills for managers look like
Financial management for a manager isn’t about becoming an accountant. It’s about a handful of practical skills. Reading a budget and understanding what the figures are really telling you. Forecasting with some confidence rather than hoping for the best. Spotting where money is being wasted and where it could work harder. And being able to build a clear case for the spend you need, in language the people holding the purse strings will understand. These are everyday skills, and they make the difference between a manager who reacts to their budget and one who manages it.
It's a skill, not a talent
Here’s the encouraging part. None of this is innate. Managers who seem naturally comfortable with numbers usually learned to be, often the hard way. The alternative to leaving people to pick it up through trial and error is simply to teach it properly, in a way that connects to their real responsibilities. When a manager understands the financial side of their role, they make better decisions, waste less, and carry more authority in the rooms where money gets discussed.
How Level 5 builds it
This is exactly what the financial management content in our ILM Level 5 Leadership and Management course is designed to do. Managers learn to plan and control a budget, understand financial information, and make sound decisions grounded in the numbers rather than instinct. Because the course is built around their actual role, they apply what they learn to their own budget as they go, so the learning sticks and the benefit shows up straight away.
Giving a manager budget responsibility without the skills to handle it isn’t setting them up to succeed. Reading a budget, forecasting and making the case for spend are learnable skills, and some of the most useful any manager can develop. If you’d like to give your managers the financial confidence their role demands, take a look at our ILM Level 5 Leadership and Management course.
