Finance for managers: Understanding key financial metrics for better decision-making
18 Mar 2025
Finance can feel like a foreign language: if you don't understand the numbers, you're flying blind. The good news is you don't need to be a CFO to make strong financial decisions.
Whether you're hiring, approving a project or setting long-term goals, financial literacy helps you back your decisions with data. Let's explore the foundations of everything finance you should know.
The importance of financial literacy for managers
Financial literacy isn't a solitary pursuit. It's the backbone of team oversight and synergy. Back in the day when I began diving deep into the numbers, I realised budgeting was less about spreadsheets and more of a playbook to align our team's efforts. Financial insights showed us cost-saving opportunities and where we could reallocate funds to high-impact projects.
As a manager, you'll likely need to present financial data. When you build enough acumen to engage in strategic conversations and support your employee's ideas, you empower your team to work more collaboratively, flexibly and effectively.
Key financial metrics every manager should know
To make informed decisions, you need to grasp a few key numbers.
- Profit and loss (P&L) statement: This shows whether your business is making money or just burning through cash. Revenue minus expenses equals your bottom line.
- Cash flow: Your business might be profitable on paper but still struggle if cash isn't coming in fast enough. Cash flow tells you whether you have enough money to cover expenses.
- Gross margin: This metric helps you understand how much money you're keeping after covering direct costs. A low gross margin might indicate your pricing strategy needs work.
- Operating costs: Keeping an eye on fixed and variable expenses helps you manage budgets effectively and spot inefficiencies.
- Return on investment (ROI): Whether it's a marketing campaign or a new hire, ROI tells you if your spending is worthwhile.
Understanding financial reports
Financial reports can look intimidating. But once you break them down, they're just a structured way of showing how a business is performing.

Start with the profit and loss statement. It tells you whether you're making or losing money. The balance sheet gives a snapshot of everything your business owns and owes at a given moment. Then there's the cash flow statement, which is all about tracking the movement of cash in and out of the business.
Instead of trying to absorb everything at once, focus on a few key figures. What's the revenue trend? Are expenses growing faster than income? Is cash flow steady? Asking simple questions like these helps you get a quick, clear picture of financial health.
Budgeting and cost control
Budgeting is really about control. Map out your fixed and variable costs. Fixed costs (like rent and salaries) stay the same, while variable costs (like supplies and marketing) fluctuate. These help you identify where you could cut back.
Next, factor in contingencies. Building a buffer into your budget means you're not caught off guard. Finally, regularly compare actual expenses against your budgeted figures. If you see spending creeping up in certain areas, adjust accordingly.
Making data-driven decisions
Effective finance feeds off strategy. When you understand the numbers, you can make smarter choices. A solid grasp of financial metrics allows you to weigh risks, identify opportunities and back up your decisions with real data.
So, next time you're faced with a business decision, don't just go with your gut — check the numbers. They'll tell you everything you need to know.
