Returning to work after parental leave: what does it mean for your finances?

The short answer: Going back can still be worth it when childcare takes most of one salary, but only a side-by-side comparison will show it. For each option, use your take-home pay, the childcare you'll really use and the 2026/27 support you can claim, such as 30 funded hours in England. Keep pensions in their own line.

"Is it worth going back?" is a big question. A calculator can handle the money part. It can't tell you how you feel about your job, your time, or how your family wants to run things.

If you and your partner split the leave, the same questions apply to both of you. Our guide to Shared Parental Leave covers what sharing does to pay and pensions.

A better starting point: what would each realistic option mean for our household, now and later?

That keeps the numbers useful without asking them to make a personal decision for you.

What options should you compare when you go back?

Compare real options, not "work or don't". Give each one a real salary and a real childcare arrangement. Your options might include:

• the same hours as before

• fewer hours, such as four days at 80% pay

• compressed hours, where you work your usual hours over fewer days

• a phased return, building your hours back up over a few weeks

Four long days on a full-time contract is not the same as four days on 80% pay, so price them separately.

Before you calculate anything, ask your employer what's on offer and get the salary in writing. In Great Britain, you can ask for flexible working from your first day in a job. That's a right to ask, not a right to get it. Northern Ireland has its own rules. GOV.UK: Flexible working.

How much more will you actually take home?

A £10,000 difference in salary isn't a £10,000 difference in spendable money. Income Tax, National Insurance, pension deductions and student loan repayments all shift. Scottish income tax bands differ from the rest of the UK. HMRC: Income Tax rates and allowances, HMRC: Rates and thresholds for employers 2026 to 2027, GOV.UK: Repaying your student loan, How much you repay.

Tax treatment depends on the individual circumstances of each client and may be subject to change in future.

Going back partway through the tax year can also make the first payslip look different from a steady monthly estimate. Ask payroll for a forecast, and treat any calculator figure as an estimate.

The number to use in the household comparison is expected net pay, not the pro-rated salary divided by twelve.

How much will your childcare really cost?

Get quotes for each arrangement you're considering. For each quote, check:

• session lengths, and whether they cover your commute

• how many weeks a year the provider opens

• holidays, and whether you pay for them

• extras such as meals, nappies and trips, which providers can charge for even on funded hours (GOV.UK: Free Childcare for Working Parents, What you'll get)

• fixed charges, like registration fees or deposits

• whether the quote already includes funded hours, so you don't take the support off twice

Don't assume four working days means four full nursery days. A partner's pattern, a childminder, school hours or family help can change what you need. And a compressed day might need a longer paid session.

For a couple, childcare is a household cost that makes the family's plan work. Taking it all off one parent's salary is a handy shortcut for the maths, not a statement about whose cost it is.

What help is there with childcare costs when you go back to work?

Funded childcare depends on which nation you're in, the child's age and other conditions. In England, working parents of children aged 9 months to 4 years can get 30 hours a week for 38 weeks of the year. That's not 30 hours every week of the year. GOV.UK: Free Childcare for Working Parents, GOV.UK: Free Childcare for Working Parents, What you'll get.

These are the government's figures for 2026/27 and assume a child who isn't disabled. GOV.UK: Free Childcare for Working Parents, Check if you're eligible, HMRC: Tax-Free Childcare, DWP: Universal Credit childcare costs.

Tax-Free Childcare and Universal Credit childcare support are separate routes. You can't get Tax-Free Childcare while you claim Universal Credit. The government's guidance says to wait for a decision on a Tax-Free Childcare application before you cancel a Universal Credit claim. So compare the whole position before you switch. HMRC: Tax-Free Childcare, Check if you're eligible.

If you're on Universal Credit, more earnings mean a lower award. For every extra £1 you earn above any work allowance, your payment goes down by 55p. DWP: Universal Credit, How your wages affect your payments. Universal Credit is based on your net take-home pay, not your gross salary. DWP: Universal Credit and earnings. Ignore the taper and you'll overstate what extra hours bring in.

Why do the first few months cost more?

Your nursery place might start before your first salary lands. Funded hours might start after your return date. In England, the start date depends on term dates and, where it applies, when you go back to work, not just the day your child turns nine months. For example, if you go back between 1 October and 31 January, you can get your hours from 1 January. GOV.UK: Free Childcare for Working Parents, When to apply.

Example: a two-month gap before support starts

If your confirmed childcare cost is £1,100 a month at first and £750 once support starts, a two-month gap adds £700 to the plan: £350 extra in each of those months. Those are made-up figures to show the timing. They aren't typical fees or a promised reduction.

Universal Credit childcare has a timing issue too, because you pay first and then report the cost. If you're starting a new job, you may be able to get all your childcare costs for the first month paid. If you're increasing your hours, the same can apply to the extra costs for one month. You can ask through your journal or your work coach rather than assuming the money arrives before the invoice does. DWP: Universal Credit childcare costs.

What happens to your pension when you go back part-time?

If you go back to the same salary, your pension contributions should carry on as normal. If you cut your hours, they'll usually go down. MoneyHelper: What happens to my workplace pension during maternity or paternity leave?.

Employer pension contributions are part of the picture, but they don't buy groceries. Show expected pension contributions in their own line, separate from monthly cash. Lower pensionable pay can change the contribution, depending on how your scheme works it out. In most automatic enrolment schemes, contributions are based on earnings between £6,240 and £50,270 a year. The legal minimum is 8% in total, with at least 3% from your employer. GOV.UK: Workplace pensions, What you, your employer and the government pay.

Leave room for what the calculation can't predict: future earnings, career progression, what you actually want, care needs, and whether the set-up feels sustainable.

How do you decide which option works?

For each option, bring together:

1. net household income

2. changes to benefits

3. childcare after support

4. extra work costs, like travel

5. essential spending

Then ask two questions: can the first few months work, and can the ongoing arrangement work?

You're not trying to prove that one parent's return "pays for itself". You're making the trade-offs visible so the family can choose.

Still got questions?

Can I get 30 funded hours while I'm still on maternity leave? You can apply from when your child is 23 weeks old. The date you go back to work affects when your hours start. Paid annual leave on your normal salary counts as having gone back. GOV.UK: Free Childcare for Working Parents, When to apply.

Can I use Tax-Free Childcare and the 30 hours together? Yes, you may be able to. The government's guidance says that as well as Free Childcare for Working Parents, you may be able to get Tax-Free Childcare or Universal Credit childcare, but not both of those. HMRC checks your Tax-Free Childcare eligibility when you apply for the free hours. GOV.UK: Free Childcare for Working Parents.

Can my employer say no to part-time hours? Yes, if they have a good business reason. They must make a decision within 2 months of your request, unless you agree to a longer wait, and tell you why if they refuse. GOV.UK: Flexible working, After the application.

Will going part-time hurt my State Pension? Not if your National Insurance record keeps building. If you earn at least £129 a week for a full tax year, you'll usually get a qualifying year anyway. Registering for Child Benefit also gives you National Insurance credits until your child is 12. MoneyHelper: What happens to my workplace pension during maternity or paternity leave?.

How much do I get back from Universal Credit for childcare? Up to 85% of your costs, capped at £1,071.09 a month for one child or £1,836.16 for two or more. You report the costs in your online account, within the assessment period you paid them or the next one. DWP: Universal Credit childcare costs.
