The Top of These Financial Mistakes are:
1. Living Beyond Your Means
Overspending is one of the most common money mistakes people make. Lifestyle inflation — upgrading your lifestyle as your income grows — often leads to debt and little savings.
Example: Buying a new car with every salary increase instead of investing the difference.

👉 How to Avoid It:
- Differentiate wants vs. needs.
- Follow the 50/30/20 budget rule.
- Automate savings before spending.

2. Neglecting an Emergency Fund
Life happens — job loss, medical emergencies, or unexpected repairs. Without a safety net, you may be forced into debt.
👉 How to Avoid It:
- Save at least 3–6 months of expenses.
- Start small (₦10,000 monthly) and grow steadily.
- Keep the fund liquid (savings account, not investments).
3. Relying Too Much on Credit Cards
Credit cards can help build credit, but over-reliance leads to high-interest debt. Many fall into the trap of making minimum payments, which only prolongs repayment.
👉 How to Avoid It:
- Pay in full every month.
- Limit card use to essential expenses.
- Track due dates to avoid penalties.

4. Not Tracking Spending
It’s easy to underestimate how much you spend daily. Small, “invisible” expenses like snacks, subscriptions, or impulse buys can eat away at your income.
👉 How to Avoid It:
- Use free expense tracking apps.
- Review your bank alerts weekly.
- Cancel unused subscriptions.
5. Delaying Investments
The biggest cost of waiting is lost time. Money not invested misses out on the power of compound interest.

Example:
- Investing $35 monthly from age 25 → about $85,000 at retirement.
- Starting at 35 → only $42,500 at retirement (same contributions, less time).
👉 How to Avoid It:
- Start small (mutual funds, ETFs, pensions).
- Increase contributions as your income grows.
- Automate investments to stay consistent.
6. Ignoring Retirement Savings
Many people assume they’ll “figure out retirement later.” But starting late means you’ll need to save far more in less time.
👉 How to Avoid It:
- Contribute to employer pension schemes.
- Open personal retirement accounts.
- Take advantage of tax-saving retirement options.
7. Not Seeking Professional Advice
DIY money management has its limits. Without guidance, you risk poor investments, tax mistakes, or not planning adequately for goals.
👉 How to Avoid It:
- Speak with a certified financial planner.
- Attend free finance workshops/webinars.
- Use advisory services like Terces Finance for tailored plans.
