Emergency fund: your first financial foundation

What is an emergency fund?

An emergency fund is money you keep for unexpected, necessary expenses. It is not investment money, shopping money, travel money, or money you plan to use for a goal you already know about.

The purpose is simple: when life interrupts your plan, you have cash available without needing to sell investments, borrow at high interest, or ask for urgent help.

Common emergencies include:

• losing your job or having your income reduced

• urgent medical costs

• essential repairs, such as a motorbike, laptop, phone, or home appliance you need for work

• family situations that require immediate cash

• temporary delays in salary or client payments

For beginners, this is one of the first foundations of personal finance. Before you think about market returns, you need a buffer that protects your basic life.

Why should an emergency fund come before investing?

Investing means accepting uncertainty. Prices can go up, down, or stay flat for a long time. If all your spare money is invested and an emergency happens, you may be forced to sell at a bad time.

That can create two problems at once:

• you lose the safety net you needed for the emergency

• you may sell an investment after it has fallen, locking in a loss instead of giving it time to recover

An emergency fund helps separate short-term safety from long-term investing. The money you might need soon stays safe and liquid. The money you invest can then be treated with more patience.

Think of personal finance like building a house. Your emergency fund is the foundation. Investments are the walls and roof. A taller structure is only useful if the foundation can support it.

A simple example

Imagine you earn 15 million VND per month and your essential monthly expenses are 8 million VND. Essential expenses include rent, food, transport, utilities, phone bills, insurance, and other costs you would still need to pay if your income stopped.

A 3–6 month emergency fund would look like this:

You do not need to reach the full amount immediately. A student, freelancer, or new employee can start with a smaller buffer first, then build it over time.

For example, saving 5–10% of your income every month can be a realistic start. The key is consistency: treat this fund as a basic financial habit, not as leftover money.

How much emergency fund do you need?

A common target is 3–6 months of essential living expenses, but the right number depends on your situation.

You may need a larger emergency fund if:

• your income is irregular or commission-based

• you are a freelancer, small business owner, or contractor

• you support family members financially

• your job or industry is unstable

• you have dependents, rent, debt payments, or medical needs

You may be comfortable with a smaller fund at first if:

• you are a student living with family support

• your essential expenses are very low

• you have stable income and few financial responsibilities

• you are still building your first savings habit

A practical beginner path is to build in stages:

1. 1. Save a starter buffer, such as 3–5 million VND or one month of essential expenses.

2. 2. Build toward 3 months of essential expenses.

3. 3. Increase toward 6 months if your income or responsibilities are less stable.

The goal is not to copy someone else’s number. The goal is to give yourself enough breathing room to handle real life without derailing your long-term plan.

Where should you keep an emergency fund?

An emergency fund should be safe, liquid, and separate.

Safe means the value should not move up and down like stocks, ETFs, gold, crypto, or other market assets. This money is for protection, not growth.

Liquid means you can access it quickly when needed. If the money is locked for a long period, has penalties, or takes too long to withdraw, it may not work well as emergency money.

Separate means it should not sit in the same place as your daily spending money. Keeping it in a separate savings account, flexible savings product, or another clearly labeled bank account can reduce the temptation to spend it.

In Southeast Asia, where many people manage money across cash, bank accounts, e-wallets, and family obligations, separation matters. If the fund is mixed with daily spending or social expenses, it becomes easier to use it for non-emergencies.

What should not count as an emergency fund?

Not every source of money is a true emergency fund.

A credit card is not an emergency fund. It can provide temporary payment access, but it creates debt and may become expensive if you cannot repay quickly.

Stocks, ETFs, crypto, and gold are not ideal emergency funds. They may be valuable assets, but their prices can fall exactly when you need money.

Money promised by someone else is also not the same as your own emergency fund. Family support can help, but it may not always be available at the right time or in the amount you need.

Your emergency fund should be money you control, can access, and can use without creating a new financial problem.

When is it okay to use the emergency fund?

Use it only for urgent, necessary, and unexpected situations.

A useful test is to ask three questions:

• Is this expense necessary?

• Is it urgent?

• Was it unexpected?

If the answer is yes to all three, it may be a real emergency. Examples include medical treatment, urgent repairs for work equipment, or essential living costs after losing income.

If the expense is predictable or optional, it should usually be planned separately. A discounted phone, holiday, wedding gift, concert ticket, or planned tuition payment may be important, but it is not an emergency if you had time to prepare for it.

Being strict with this rule protects the fund for the moments when you truly need it.

How to build and manage your emergency fund

Start with your essential monthly expenses. List the costs you must keep paying if your income stops: housing, food, transport, utilities, phone, insurance, debt minimums, and essential family responsibilities.

Then choose a first target. If 3–6 months feels too large, start with one month or a small fixed amount. A starter fund is better than waiting for the perfect number.

Next, automate or schedule your savings. Move money into the fund right after income arrives, even if the amount is small. This makes saving part of the system instead of a decision you repeat every month.

Finally, replenish it after use. If you use part of the fund for a real emergency, pause non-essential goals or new investing contributions until the fund is back to a safe level.

Common mistakes beginners make

One common mistake is investing before having any cash buffer. This can make a normal life problem feel like an investment crisis.

Another mistake is keeping the fund too accessible. If the money sits in the same wallet or account used for daily spending, it may slowly disappear.

A third mistake is treating the fund as a performance asset. Chasing higher returns with emergency money can expose it to loss, lockups, or withdrawal delays.

The fund’s job is not to make you rich. Its job is to keep one bad month from becoming a long-term financial setback.

Is an emergency fund enough by itself?

No. An emergency fund is the first layer of protection, not the whole financial plan.

After you have a basic buffer, you can continue learning how to manage income, repay debt, save for goals, and invest for the long term. The fund simply gives you more control while you learn those next steps.

Before investing, ask yourself:

• Do I have at least a small emergency buffer?

• Am I using money I will not need for essential expenses soon?

• Can I handle a temporary drop in investment value without selling in panic?

• Do I understand the product I am investing in?

• Have I considered debt, fees, taxes, currency risk, and platform or custody risk where relevant?

If the answer is not clear yet, it is reasonable to keep learning and strengthen your foundation first.
