"How much should I have in savings?" sounds like it should have one answer. It doesn't, because savings do several different jobs. But there's a clear order to tackle them in, and the first one, an emergency fund, has a number you can calculate in about ten minutes.
Start with the emergency fund
An emergency fund is money set aside for things you can't plan: losing your job, a medical bill, a car repair, a broken water heater, a last-minute flight home. Its job isn't to grow. Its job is to stop a bad week turning into credit card debt.
Many households don't have one. In the Federal Reserve's latest Survey of Household Economics and Decisionmaking, carried out in October 2025, 63% of US adults said they would cover an unexpected $400 expense with cash or its equivalent. That means more than a third would need to borrow, sell something, or couldn't cover it at all.
The standard guidance is three to six months of essential expenses. Not three to six months of salary, and not your full spending, but what you'd need to keep the lights on if your income stopped.
How to calculate your emergency fund
Add up the costs you couldn't cut if you lost your income tomorrow:
| Essential expense | Example monthly amount |
|---|---|
| Rent or mortgage | $1,450 |
| Utilities, phone and internet | $230 |
| Groceries (basic, not your usual) | $450 |
| Transport (fuel, insurance, transit) | $300 |
| Insurance (health, renters) | $220 |
| Minimum debt payments | $250 |
| Childcare, medication, other must-pays | $100 |
| Monthly essentials | $3,000 |
Then multiply:
- 3 months: $3,000 × 3 = $9,000
- 6 months: $3,000 × 6 = $18,000
Leave out the things you'd stop immediately in a crisis: eating out, holidays, most subscriptions, new clothes. That's why your emergency number is usually well below your normal monthly spending.
The free emergency fund calculator does this sum for you. Enter your essential costs, tick what applies to your situation, and it suggests how many months to aim for and shows when you'll get there.
If you don't know your real numbers, use your last three months of bank statements, or track for a month. Our list of monthly expenses is a good checklist so you don't miss anything, and the free expense tracker totals it by category.
Three months or six? How to choose
Where you land in the range depends on how likely and how long a loss of income would be.
| Aim for 3 months if | Aim for 6 months or more if |
|---|---|
| You have a stable job in a field with lots of openings | Your income is irregular: freelance, commission, seasonal |
| There are two incomes in your household | You're the only earner, or you have dependents |
| You have no dependents | You work in an industry prone to layoffs |
| You rent and your car is reliable | You own an older home or car that could need big repairs |
| You have other accessible savings | You have a health condition that could affect your work |
Self-employed people often aim for six to twelve months, because income can drop with no notice period and no severance.
Where to keep it
Your emergency fund should be safe, separate, and quick to reach.
- Safe: a savings account, not invested in shares. The stock market can fall exactly when you lose your job.
- Separate: not in your everyday account, where it blends in with spending money. A separate account at a different bank adds a small, useful bit of friction.
- Quick to reach: money you can get within a day or two, without penalties. A high-interest or high-yield savings account usually fits.
It's fine, and sensible, for this money to earn interest. Just don't lock it away to get a slightly better rate.
What to do if you're starting from zero
Six months of expenses can feel impossibly far away. Don't aim for it on day one. Build it in stages:
- A starter buffer of $1,000 (or one month of rent). Enough to cover most car repairs and surprise bills without a credit card.
- One full month of essentials.
- Three months.
- Six months, if your situation calls for it.
If you have high-interest debt, many people find it makes sense to build the starter buffer, then focus on the debt, then come back to the full fund. Credit card interest usually costs far more than a savings account earns. Our guide to debt snowball vs avalanche covers how to order your payments.
To work out how long each stage will take, enter what you've saved and what you can add each month into the emergency fund calculator. It shows each milestone, from one month of cover up to your full target, with the month you'll reach it. For other goals, like a house deposit, the savings goal calculator works backwards from a target date.
How much should you save each month?
A common rule of thumb is the 50/30/20 split: 50% of take-home pay for needs, 30% for wants, and 20% for savings and extra debt payments. The 50/30/20 budget calculator shows what that looks like with your own numbers.
Twenty percent is a target, not a pass mark. If you can only save 5% right now, start there and set up an automatic transfer on payday. Raise it a little each time your income goes up. That habit, more than any particular percentage, is what builds savings over time, and it's the simplest defence against lifestyle creep.
How much should you have in savings by age?
Once your emergency fund is in place, the bigger long-term number is retirement savings. One widely used set of benchmarks comes from Fidelity, which suggests having a multiple of your salary saved for retirement by each age:
| Age | Retirement savings target |
|---|---|
| 30 | 1× your annual salary |
| 40 | 3× your salary |
| 50 | 6× your salary |
| 60 | 8× your salary |
| 67 | 10× your salary |
Treat these as rough signposts, not a test. They assume you start saving in your twenties and retire in your late sixties. Plenty of people start later and catch up. Pensions, home equity, and your country's state retirement system all change the picture, so if retirement is your main question, it's worth talking to a qualified adviser.
To see how regular contributions grow over time, try the compound interest calculator. It's a useful reminder that starting early with small amounts often beats starting later with larger ones.
The short version
- First, a starter buffer of around $1,000.
- Then an emergency fund of three to six months of essential expenses, more if your income is uncertain.
- Alongside that, pay down high-interest debt.
- Then build long-term savings for retirement and big goals, aiming for around 20% of take-home pay when you can.
None of it works without knowing your monthly essentials, which is why tracking your spending comes first. If you want logging to take seconds, TallyMsg lets you text each purchase in Telegram or WhatsApp and builds the monthly breakdown for you.
