Pregnancy

How much should you actually save before the baby comes?

Don't start from a national average. Work out your own number: the income your household actually loses while she's off work, plus about three months of ordinary expenses as a buffer, plus a few hundred for gear you'll genuinely need. For most couples the lost income dwarfs everything a baby-cost article talks about.

How to work out your own number

There is no national figure worth having, because the answer is dominated by your income gap and your childcare costs and both are local. This is the sum instead.

  1. Her take-home pay, per month. The real figure from a payslip, not the salary.
  2. Minus the paid parental leave she will actually receive — from the government scheme and from her employer, both in writing. Employers vary enormously and the difference is often thousands.
  3. Times the number of months she will be off. That product is the income gap, and it is nearly always the largest number on the page.
  4. Plus three months of your household's ordinary outgoings as a buffer, in a separate account. Its job is that a broken car doesn't become a crisis in the same month as a newborn.
  5. Plus the gear — a few hundred if you are sensible, because much of it arrives borrowed, gifted or secondhand.

your number = (her take-home − parental leave paid) × months off + 3 months' outgoings + gear

The three numbers that matter

  1. The income gap. Her normal take-home, minus whatever paid parental leave she'll actually receive, times the number of months she'll be off. Get the real figures from your government scheme and her employer, in writing. This is nearly always the biggest number by a distance.
  2. The buffer. Three months of your household's ordinary outgoings, sitting in a separate account you don't look at. Its job is that a broken car or a boiler doesn't become a crisis in the same month as a newborn.
  3. The gear. Genuinely a few hundred if you're sensible, because a large share of it is borrowed, gifted or bought secondhand.

What actually costs money, month to month

What genuinely doesn't need buying new

What to do this month

  1. Find out your actual parental-leave entitlements — both of you, in writing, from the scheme and the employer.
  2. Set up an automatic transfer on payday into a separate account. The amount matters less than the automation.
  3. Cancel two subscriptions you don't use. It's small, and it's momentum.
  4. Agree a rule for who can spend what without asking. Money arguments after a baby are usually about surprise, not amount.

Quick answers

Is there a single number I should aim for?

No honest one, because the answer is dominated by your income gap and your childcare costs, both of which are local. Anyone quoting you a universal figure is guessing.

What's the most commonly underestimated cost?

Time off work — both hers and, later, the days you'll take when the baby is ill and nursery won't take them.
