Why Three Months of Expenses Isn't Always Enough
Three months of expenses. That is the number financial advice has settled on as the standard emergency fund target. It is repeated so often it has started to feel like a law of nature. But it comes from research done in Western economies with stable currencies, deep unemployment insurance, and formal employment contracts. Ghana is not that economy.
Where the Three-Month Rule Comes From
The original guidance was designed around the idea that if you lose your job, you need enough money to cover your expenses while you find a new one. In a labour market with strong demand, formal job listings, and unemployment benefits topping up your income, three months is reasonable. In Ghana's predominantly informal economy, job searches can take longer, income streams can be multiple and fragile, and there is no state unemployment safety net.
The Cedi Factor
There is a second problem specific to Ghana: currency risk. If your emergency fund sits in a standard cedi savings account and the cedi depreciates significantly — as it did in 2022, losing over 50% of its value against the dollar — your 'three months of expenses' can quietly shrink to two months in real import-adjusted terms. Some of your emergency costs (medical, electronics, imported goods) are priced in USD or track the exchange rate closely.
Who Actually Needs Six Months
You should target six months of expenses if any of the following apply:
You are self-employed or have irregular income
Your household has a single earner
You are in a sector with volatile employment (construction, media, hospitality)
You have dependants — children, parents, siblings — who rely on your income
You have no family safety net to call on in a true emergency
You carry consumer debt that could accelerate costs in a crisis
What Counts as an Expense
Be honest about what belongs in the calculation. Your emergency fund should cover your actual monthly burn — rent, food, utilities, transport, loan repayments, school fees, any regular medical costs. It should not include discretionary spending like eating out or subscriptions. Strip it back to what you need to keep your household functioning.
Where to Keep It
The emergency fund has one job: be available when things go wrong. That means liquidity beats return. Keep the core fund in a regular savings account — not T-bills (which have a lock-in period), not stocks (which can drop 30% the week you need them). If you want to squeeze more return, keep one month in a savings account and the rest in 91-day T-bills you roll over, giving you liquidity on a rolling 91-day basis.
Three Months Is a Starting Point, Not the Finish Line
Build to three months first — that is a real and meaningful milestone. But treat it as the floor, not the ceiling. As your responsibilities grow and your income becomes more reliable, push toward six. The cost of being wrong about three months being enough is paid during the worst possible moment of your life.
