Detty December has officially entered the chat.
It’s the season of endless concerts, yelling oblee at the top of your lungs, late-night club hopping, last-minute flights, bottomless brunches, perfectly timed algorithm-driven “buy now” nudges tugging at your heartstrings and your pocket, and a social calendar that doubles as cardio. But while December outside is ready to be “detty,” your bank account doesn’t have to be the one taking the beating.
This guide isn’t about killing your fun. It’s about helping you enjoy the entire month without spending January recovering from December. Think of it as your practical game plan for staying in control while still having the time of your life.
Let’s get into it.
Budget, Budget, Budget!
If there’s one month where your money needs a plan, it’s December.
Without a budget, Detty December quietly shape shifts into “Debt-y December,” and before you know it, you’re Googling “how to recover from overspending.”
Start by writing down what you can realistically afford to spend on outings, pop-ups, gifts, travel, and random December spontaneity. Work backward from your income, not forward from your wish list.
You don’t have to budget every Naira down to the last grain of rice; you just need clear boundaries.
If you want help keeping your December fund separate and safe, park your money in the Chapel Hill Denham Money Market Fund under the InvestIN tab on the InvestNaija app. It keeps your spending money liquid but still earning steady returns while you decide what deserves your coins.
Track Your Spending
December spends fast.
Transport doubles. Drinks triple. And the soft life has hidden charges your budget didn’t warn you about.
The only way to stay in control is to track your spending in real time.
Keep track of your debit alerts or check your banking app after each outing. Know what’s left. Don’t assume, don’t guess, don’t “I will check later.”
Instead of leaving everything in your bank account where money evaporates, use InvestNaija to segment your funds. Keep your savings and investments (InvestNaija Pro Tip: Aim for at least 20% of your monthly income i.e. N100,000 if you earn N500,000 monthly, and remember the ever-handy 13th month salary buffer) out of reach and let your bank account carry only what you’re willing to part with. That separation alone can save you from impulse spending.
Just Say No!
Contrary to popular belief, the calendar hitting December 1st does not remove your right to say no.
You don’t need to attend every event.
You don’t need to split every bill.
You don’t need to jump into every group plan born out of pure December FOMO (fear of missing out).
Saying no isn’t stinginess; it’s strategy.
If an outing doesn’t fit your budget, sit it out. Your real friends will respect your boundaries, and anyone who doesn’t wasn’t trying to help you anyway.
Focus on the few events that actually matter to you. Quality over quantity keeps your finances intact and your mind guilt free.
Decide What You Want Your December to Mean
December shouldn’t be a free-for-all.
What do you want this month to stand for?
Is it rest?
Is it spending time with family?
Is it catching up with old friends?
Is it rewarding yourself for making it through the year?
Once you define your December, you’ll spend more intentionally. Every financial choice will align with what truly matters to you, rather than what the timeline is shouting about.
If you want to start 2026 stronger, consider locking in some of your end-of-year income into a CHD Mutual Fund such as the Nigerian Dollar Income Fund which provides dollar-denominated returns if you’re looking to hedge against Naira devaluation. Future-you will thank present-you for choosing purpose over pressure.
Build a December No-Guilt Fund
This is one of the smartest defensive moves you can make.
Create a small fund for guilt-free fun money you can spend without regret, explanations, or panic.
Load it at the beginning of the month When it’s gone, it’s gone.
It removes the pressure and keeps you honest.
If you want that fund to grow a bit while you wait for 24th-26th madness, move it into Chapel Hill Denham’s Money Market Fund on InvestNaija. Your money stays accessible but works for you in the meantime.
Protect January from December
A lot of people treat December like it’s detached from the rest of the year. It’s not. January will come, and it will come with bills, school fees, rent deadlines, and reality.
Put something aside now so January doesn’t greet you with stress.
Split your income: a portion for December enjoyment, a portion for January survival, and a portion for investments.
For your January protection plan, take the risk assessment quiz on InvestNaija and consider the selection of Chapel Hill Denham Mutual Funds on InvestNaija steady, managed, and easy to top up.
The Bottom Line
Detty December doesn’t have to be financially chaotic.
You can enjoy yourself, attend the events that matter, spoil the people you love, and still step into January with dignity and a functioning bank balance.
Just remember the key principles:
Plan your money. Track your spending. Say no without apology. Define your December. And protect January like your life depends on it because it does.
When in doubt, let InvestNaija be your financial buffer.
Your December can be fun, but your financial future still deserves care.
