A Complete Guide to SPL Teachers Plus: What You Get and How It Helps You Plan With Confidence

Planning maternity leave as a teacher can feel complicated — between OMP, SMP, SPL, school holidays and return-to-work dates, your timeline can quickly become confusing. SPL Teachers was built to make that process simpler, clearer and more personalised for every teacher.

The SPL Teachers Calculator is free to use, and always will be. But for anyone who wants a deeper look at their timeline, clearer insight into pay, and tools that help you make the most of your leave, Plus gives you access to a more powerful planning experience.

This guide explains what Plus gives you, how each feature works, and why thousands of teachers choose it to support their planning.


Why Teachers Choose SPL Teachers Plus

SPL Teachers isn’t funded by any organisation — it exists because teachers across the UK need a clear way to understand their maternity and Shared Parental Leave options.

By choosing Plus, you’re supporting the project and unlocking features designed to help you:

  • Understand your pay clearly

  • Plan your leave around school holidays

  • Compare different maternity/SPL timelines

  • Prepare official paperwork with confidence

  • Save, edit and revisit your calculations whenever you need

Every pregnancy is different, and every teacher’s timeline is shaped by unique factors — your due date, your school’s holidays, your OMP policy, and your personal preferences. Plus gives you the tools to see what’s possible and build the best plan for your circumstances.


What You Get With Plus

Below is a deeper look at every tool that comes with Plus and how it makes planning your leave easier.

1. Salary Calculator — See Your Pay Clearly Across Maternity, OMP and SPL

The Salary Calculator is one of the core Plus features. It is designed specifically for teachers, taking into account:

  • Your yearly salary

  • Whether you’re paid monthly or weekly

  • Your OMP policy

  • SMP and SPL rates

  • Your school holiday pattern

  • Tax, pension and student loan deductions

How it helps

The calculator shows you:

  • How your pay is made up across maternity, OMP, SMP and SPL

  • Exactly when each type of pay starts and ends

  • Where school holidays give you additional paid time off

  • Whether shifting your return-to-work date increases your total pay

  • How SPL can extend your time at home or increase your income

You’ll see clear month-by-month changes, including when OMP ends, when SMP begins, and where SPL provides additional flexibility.

Explore different scenarios

You can experiment with different decisions:

  • What if you return to work in a school holiday?

  • What if you take SPL in different blocks?

  • What if your maternity end date changes?

  • What if you shorten or lengthen OMP?

The calculator does all the maths for you — saving you hours of trying to work it out manually.


2. Monthly Pay Breakdown — Plan Ahead With Confidence

Every monthly payslip changes during maternity. Plus shows a clean, simple breakdown for every month including:

  • Gross pay

  • Type of pay (OMP/SMP/SPL)

  • Tax deductions

  • Pension deductions

  • Student loan deductions

  • Final estimated take-home pay

Why this matters

Seeing your income month by month helps you:

  • Budget more accurately

  • Spot the months where pay drops

  • Plan savings and spending

  • Make informed decisions about extending or shifting your leave

  • Understand how return-to-work incentives work around holidays

Teachers often find this breakdown provides clarity they haven’t been able to get from school HR or online calculators.


3. Example Maternity Form PDF — A Ready-Made, Pre-Filled Summary

Once your plan is complete, you can export a sample maternity form PDF.

This includes:

  • Your maternity leave start date

  • Your end date

  • OMP, SMP and SPL periods

  • Any back-to-work blocks

  • Notes or adjustments

  • Your return-to-work date

  • Key dates for HR or payroll

Why this is useful

School HR teams often ask for forms that teachers aren’t sure how to fill in. This PDF:

  • Mirrors typical school maternity forms

  • Uses the same structure HR expect

  • Lets you copy and paste dates easily

  • Gives you a reference to double-check before submitting official paperwork

  • Can be shared with your partner or HR for review

It removes the guesswork and reduces the risk of errors or incorrect dates.

5. Edit Existing Calculations — Make Changes Without Starting Again

With Plus, you can revisit and update any previous plan you’ve created.

This is helpful if:

  • Your due date changes

  • Your school calendar is updated

  • Your OMP policy changes

  • You want to explore SPL options late into maternity

  • You’re planning a second (or third) pregnancy

  • You just want to tweak a few dates

The calculator automatically updates everything — you don’t need to re-enter earlier information.

6. Duplicate Calculations — Compare Options Easily

This feature lets you create copies of your plan to explore different options side by side.

Examples:

  • Compare returning to work before vs after Christmas

  • Test SPL blocks across different school holidays

  • Compare maternity-only vs maternity + SPL paths

  • Explore extending your leave length

  • Test two different OMP policies if you are switching schools

Teachers often use this feature to create:

  • A “best financial outcome” plan

  • A “maximum time off” plan

  • A “minimum disruption to school” plan

  • A “partner shared leave” plan

You can duplicate as many versions as you need and switch between them instantly.
