calculator maternity pay

If you searched for a calculator maternity pay tool, you are probably trying to answer one key question: “How much money will I actually receive while I am off work?” This page gives you a practical estimator plus clear guidance so you can plan leave, budget monthly expenses, and reduce uncertainty.

What this calculator helps you estimate

This maternity pay calculator is designed for UK-style statutory maternity pay (SMP) planning. It estimates:

• Whether your average weekly earnings meet a basic eligibility threshold.
• First 6 weeks at 90% of average weekly earnings.
• Remaining weeks at the lower of 90% earnings or the statutory weekly cap.
• Optional employer top-up if your company offers enhanced maternity terms.
• Total projected maternity pay and an average monthly amount.

How maternity pay is commonly structured (UK)

Weeks 1 to 6

The first part is often calculated at 90% of your average weekly earnings. If your weekly earnings are high, this phase can be significantly above the standard statutory cap.

Weeks 7 to 39

For the remaining period, pay is usually the lower of:

• 90% of your average weekly earnings, or
• the statutory weekly maternity rate in effect for that tax year.

How to use the calculator maternity pay tool

1. Enter your average weekly earnings before deductions.
2. Choose how many paid maternity weeks to estimate (up to 39).
3. Confirm the weekly statutory rate and lower earnings limit.
4. Add employer top-up values only if your contract includes enhanced pay.
5. Click calculate and review the full breakdown table.

Worked example

Suppose your average weekly earnings are £650 and you plan 39 weeks of maternity pay:

• First 6 weeks: 90% of £650 = £585 per week.
• Next 33 weeks: lower of £585 and the statutory rate (for example £184.03), so £184.03 per week.
• Total estimate = (6 × £585) + (33 × £184.03).

If your employer adds a top-up, that amount is added separately and shown clearly in the calculator output.

Common planning mistakes to avoid

• Using monthly salary instead of weekly earnings: this can overstate or understate results.
• Ignoring payroll deductions: calculator totals are gross estimates unless your payroll confirms net values.
• Missing policy details: some employer schemes have conditions like return-to-work clauses.
• Not updating rates annually: statutory amounts can change each tax year.

Budgeting during maternity leave

Create a “must-pay” monthly baseline

List rent/mortgage, food, utilities, transport, insurance, and medical costs. Compare your baseline with your estimated monthly maternity income from the tool.

Build a maternity buffer

If possible, set aside savings before leave starts. Even a modest emergency fund can reduce stress during lower-pay months.

Coordinate with partner income and benefits

Many families forget to combine maternity pay with partner income, shared parental leave impacts, and any local support programs. A complete household cashflow view gives better decisions.
