You are thinking about a baby, you already save a little, and every page you open says to put away some magic number of months of expenses. This article skips the magic number. It gives you worksheets that build two targets from your own budget: a baby fund for the costs you can see coming, and an emergency fund for the ones you cannot. Then it turns both into a monthly amount you can actually set up.
Two funds, two jobs
One pile of savings is hard to judge. If it has to pay for a crib, a few months of lower income and a broken car, you never know whether you are on track. Two named funds make each question answerable: is the baby fund on target for the date we chose, and is the emergency fund ready for the surprise we are most likely to face?
Baby fund
- Costs you can name and roughly date
- Income gap, one-off purchases, home or transport changes, the first months of running costs
- Has a target date, so it has a monthly amount
Planned spending: you expect to use it, so aim to have it ready by a date.
Emergency fund
- Costs you cannot date
- A repair, a lost job or fewer hours, a broken phone or appliance, a sudden trip
- Has no date, so it is sized by risk and refilled after you use it
Protection: you hope not to use it, and you top it up when you do.
If income drops, the emergency fund is what keeps the baby fund from being raided. Keeping them apart, even as two lines in a sheet, makes that trade-off visible instead of accidental.
Step 1: write the monthly budget for life with a baby
Both targets rest on one document: what a normal month will cost once the baby is part of the household. Start from your real budget, not an idealized one. Take three recent months of statements, average each line, then add the new lines as blanks. Leave a cell empty when you do not know it yet, because a guessed number looks like a fact a month later.
- 1
Average your last three months, line by line
Housing, utilities, groceries, transport, debt payments, subscriptions and everything else that recurs. Use statements, not memory.
- 2
Mark each line essential or flexible
Essential means you would still pay it in a hard month. Flexible means you could cut it. The essential total is the base of the emergency fund.
- 3
Add the baby lines as blanks
Childcare, diapers and food, clothes, a larger home or a second car if you expect one. If you do not know a line, write "unknown" and the next step to find out.
- 4
Change the income side to match your plan
If one of you will earn less or pause for a while, enter what you would really receive. The one-income dry run lets you test that month before you commit.
| Line | Today | With a baby | Essential or flexible |
|---|---|---|---|
| Housing | Essential | ||
| Utilities and phone | Essential | ||
| Groceries | Essential | ||
| Transport | |||
| Debt payments | Essential | ||
| Childcare | 0 | ||
| Baby supplies | 0 | ||
| Everything else | Flexible | ||
| Income after tax, all adults | - |
The line names are a suggestion. Add or delete rows to match your household.
Do you have a rough list of what a baby adds to a budget? A baby budget before you start walks through the lines, and a ledger to track baby expenses keeps the real numbers once they begin.
Step 2: size the baby fund
The baby fund is the sum of four parts. Each comes from your own documents, your employer's pay terms or your own shopping list, never from a website's average.
| Part | What goes in | Where the number comes from | Your number |
|---|---|---|---|
| Income gap | (Monthly take-home now - monthly take-home in the new arrangement) x months | Your pay terms and the months you plan to work less | |
| One-off purchases | Gear and furniture you decide to buy new | Your own list, with borrowed and gifted items taken out | |
| Home or transport changes | A deposit, a move, a larger car, childcare registration | Quotes you have asked for, not guesses | |
| First months of running costs | The baby lines from Step 1 x the months you want covered | Your Step 1 worksheet | |
| Baby fund target | Add the four parts | - |
Every cell is a fill-in. A figure copied from an average will not match your household.
Each part has its own article. For the one-offs, a pre-baby shopping budget separates what to buy first from what can wait; its total feeds the second row. For the income side, the one-income test shows how a month feels before you rely on it.
Step 3: size the emergency fund from your own risks
For the emergency fund, the consumer-finance guide suggests looking at the unexpected expenses you have had before and what they cost, then setting a goal from that. It lists car or home repairs and lost income as examples, and says to decide in advance what counts as an emergency so you apply the rule consistently. That gives you a method with two inputs: your history and your exposure.
Build your emergency target from three lists
Look back (the last two or three years)
- List every unexpected cost you remember: repairs, an urgent trip, a broken device.
- Write the amount next to each, or your best memory of it, and mark what came from savings and what from credit.
- Note the largest single surprise. It is a floor for your target, not a ceiling.
Look ahead (what changes with a baby)
- Which items get more likely: a second car, a larger home, a commute that stops working?
- How exposed is your income: one earner, a contract that ends, seasonal work?
- Who could you call for help, and what would that cover? Write it as a note; do not count it as money.
Decide
- Pick the number of months of essential costs you want covered, and write down your reason. You choose it.
- Multiply the essential total from Step 1 (the "with a baby" column) by those months, and compare with your largest surprise.
- Set the target at the higher of the two, or at a smaller first goal if the full figure feels out of reach, and pick a date to revisit it.
| Item | Your figure |
|---|---|
| Essential monthly costs with a baby (from Step 1) | |
| Months you want covered, and why | ____ months because ____ |
| Essential costs x months | |
| Largest surprise on your list | |
| Emergency target (the higher of the two, or a first goal) |
Pages that suggest a fixed number of months are offering a rule of thumb. Treat it as one input beside your own list.
A one-income household carries more of its risk on one pay packet, and you may reasonably want more months. How many is your call, and you can change it. A bigger number is not a promise of safety, and a smaller one is not a failing.
Step 4: count back from a date and test it for a month
Two targets become a plan when each gets a date and a monthly amount. The baby fund has a natural date: the point by which you want it ready. Pick it together and write it down. The emergency fund can reach its target later, because it protects you whether or not that date arrives.
| Fund | Target | Already saved | Months left | Monthly amount |
|---|---|---|---|---|
| Baby fund | (Target - saved) / months | |||
| Emergency fund | (Target - saved) / months | |||
| Both together | - | - | - | ____ per month |
| Example only, made-up round numbers | 3,000 | 600 | 12 | 200 per month |
The last row is invented to show the arithmetic and is not a recommendation. If the two monthly amounts do not fit your budget, change a month, a target or the order, not the arithmetic.
A consumer-finance guide's save automatically article follows the same logic: set a goal, work out how much to save each month, follow the plan for one month, compare your real numbers with your projections and adjust. Only then automate.
Month 1
Open two labelled places and run a test month
Two accounts, two sub-accounts or two lines in a sheet. Move the planned amounts by hand once and see whether the rest of the month still works.
Month 2
Automate the transfers
A consumer-finance guide describes two ways: ask your bank to move money regularly from checking to savings, or ask your employer to send part of each paycheck straight to savings. Watch the balance so an automatic transfer never leaves the account short.
When money arrives
Add one-time money
A refund, a bonus or a gift can go partly or wholly into one fund. A consumer-finance guide lists this among its starting points.
Every month
Look at both balances for ten minutes
Compare with the table. If you are behind, adjust the monthly amount or the date, not the goal in your head.
Halfway
Redo Step 1 with fresh statements
Real months replace guesses. Update the baby lines and recompute both targets.
Where to keep the money, in plain terms
The consumer-finance guide describes a good place for emergency money as safe, easy to reach and not too easy to spend on other things. It names a bank or credit union account as generally among the safest options, and also lists a prepaid card and cash at home, noting that cash can be lost, stolen or destroyed. Rules and products differ widely between places and we have not checked any, so we recommend no product and quote no rate.
- Separate from daily spending. A dedicated place makes accidental spending harder and the balance easier to see.
- Reachable within days. Emergency money should not be locked away or depend on selling something.
- Not a bet. Money you need by a date is not the place for risk. This article gives no investment advice.
- Written rules for use. Decide in advance what counts as an emergency, and refill the fund after you use it.
The money meeting: one agenda for two people
Savings plans fail less from arithmetic than from silence. One of you imagines a cushion, the other imagines a holiday, and nobody says so. A single meeting with an agenda fixes most of it. Hold it at a calm time, with the worksheets open, and share the screen if you are not in the same room. If you are planning alone, run the same agenda with a trusted friend or just with your notes.
- 1
Minutes 0-10: facts only
Read out the Step 1 totals. No opinions yet. Each person adds any line the other forgot.
- 2
Minutes 10-20: what scares you, what excites you
One sentence each on the money worry that comes up most. Listen without fixing. This tells you which fund matters more to each of you.
- 3
Minutes 20-35: pick the numbers
Fill in the months for the emergency fund and the date for the baby fund. If you disagree, write both options and test each for a month.
- 4
Minutes 35-45: assign owners and a next date
Who opens the places, who sets the transfers, who runs the monthly check, and when you meet again.
| Task | Owner | By when | Done |
|---|---|---|---|
| Average three months of statements | |||
| Fill in the four baby-fund parts | |||
| Write the emergency history list | |||
| Open the two labelled places | |||
| Run the first test month | |||
| Set the automatic transfers |
For a deeper conversation about how the two of you handle money day to day, joint finances for couples is a good next read, and if one of you feels ready sooner than the other, when one of you is ready and the other is not offers words for it.
If the numbers do not fit
Three moves often help, in this order. Trim the one-off line, since borrowed and gifted items cost nothing. Move the date and give the baby fund more months. Then look at the income side, because a different split of hours can change the whole picture.
Frequently asked questions
How many months of expenses should we save before a baby?
A consumer-finance guide gives no number and says the right amount depends on your situation. Use Step 3: choose a number of months with a reason, compare it with your largest past surprise, and revisit it as your budget becomes clearer.
Should the baby fund and the emergency fund be separate?
It is a suggestion, not a rule, but it makes both easier to judge. The baby fund has a date and gets used; the emergency fund has no date and gets refilled. Two labelled places stop a planned purchase from quietly eating your protection.
Do we need a bigger emergency fund on one income?
Possibly, because one pay packet carries more of the risk, and the number of months is yours to choose. Size it from your essential costs and from what you would do if that income stopped. The [one-income dry run](post:baby-on-one-income) shows how the budget feels first.
How do we start if we can only save a little?
Start with a small amount and a test month, then automate it. Part of any one-time money, such as a refund or a gift, can go in as well. Raise the amount later if you can.
Should we use a credit card for baby costs instead?
That is your decision and we give no advice on it. A consumer-finance guide notes that relying on credit cards or loans for an emergency can make it much larger through interest and fees. A fund gives you the choice; if you borrow, read the terms first.
What is the difference between a savings account and an emergency fund?
A savings account is a place; an emergency fund is a purpose. You can use one account per fund, or one account with separate lines in your sheet.
