UK Statutory Redundancy Pay Calculator: How to Calculate Redundancy Pay

Redundancy is one of those business decisions you never want to make in a rush.

If you’re a small business owner, you’re usually balancing cashflow, team morale, customer expectations and compliance - all at the same time. And when redundancy becomes unavoidable, one of the first practical questions is:

“What do we actually have to pay?”

This guide walks you through a statutory redundancy pay calculator-style approach (i.e. the rules and steps you’ll follow to calculate statutory redundancy pay), with plain-English explanations, worked examples, and the common traps that catch employers out.

Important note: This article is general guidance for UK employers. Redundancy outcomes can change depending on your contracts, policies and the facts, so it’s worth getting tailored advice before you press go - especially if you think there’s any risk of an unfair dismissal or discrimination claim.

What Is Statutory Redundancy Pay (And When Do You Owe It)?

Statutory redundancy pay is the minimum redundancy payment an eligible employee is entitled to by law when their role is genuinely redundant and you dismiss them for redundancy.

In broad terms, it’s based on:

• their age during each year of service
• their length of continuous service
• their weekly pay (subject to a statutory cap)

Statutory redundancy pay is separate to other payments you may need to make when employment ends, such as:

• notice pay (or payment in lieu of notice)
• accrued but untaken holiday
• any contractual redundancy pay (if your contract/policy is more generous than the statutory minimum)

Most commonly, an employee becomes eligible for statutory redundancy pay when they:

• are an employee (not genuinely self-employed)
• have at least 2 years’ continuous service with you
• are dismissed by reason of redundancy

Even if an employee isn’t eligible for statutory redundancy pay (for example, under 2 years’ service), you still need to handle the redundancy process fairly and lawfully. Your Employment Contract may also add extra entitlements, so it’s worth checking what you’ve agreed in writing.

How Does A Statutory Redundancy Calculator Work? (The Legal Formula)

If you’ve searched for a statutory redundancy pay calculator, you’re usually looking for the same thing: the formula behind the number.

In the UK, statutory redundancy pay is calculated using a multiplier based on age for each full year of service (up to a maximum), multiplied by weekly pay (subject to a cap).

Step 1: Confirm The Employee’s Continuous Service

You count full years of continuous employment with you. The statutory scheme caps the years you can count at 20 years.

So even if someone has 25 years’ service, you only use 20 years for the statutory calculation.

Step 2: Apply The Age Band Multipliers

For each full year of service, the employee gets:

• 0.5 week’s pay for each full year of service where they were under 22
• 1 week’s pay for each full year of service where they were aged 22 to 40
• 1.5 weeks’ pay for each full year of service where they were aged 41 or older

This often surprises employers because you don’t pick one multiplier for the employee overall - you apply the multiplier to each year depending on the employee’s age during that year.

Step 3: Work Out “A Week’s Pay” (And Apply The Statutory Cap)

The calculation uses “a week’s pay”, but:

• there are legal rules about how weekly pay is worked out (it isn’t always as simple as salary/52), especially where hours or pay vary
• there is a statutory limit (cap) on weekly pay used for redundancy calculations, even if the employee actually earns more

For employees with normal working hours, weekly pay is often based on their normal gross weekly pay. For employees with variable hours or pay (for example, shift work, overtime, commission or irregular hours), you may need to use the legally required averaging approach over the relevant reference period and include the correct pay elements. If you’re unsure, it’s worth checking the statutory rules before you finalise figures.

The weekly pay cap changes from time to time. If you’re doing calculations today, make sure you’re using the cap that applies at the effective date of termination (not when you first started consultation).

Step 4: Add It Up (Up To The Statutory Maximum)

Once you’ve applied the correct multiplier for each qualifying year and multiplied by the capped weekly pay, you’ll have the statutory redundancy pay figure.

Practical tip: Keep a written record showing how you arrived at the amount. If there’s a later dispute, being able to show the workings (like a redundancy calculator print-out) can save you a lot of time.

Redundancy Calculation Examples (So You Can Sense-Check Your Numbers)

Below are simplified examples to show how redundancy pay is calculated. (Real-life calculations can be more complex where pay varies.)

Example 1: Employee Aged 30 With 4 Full Years’ Service

• Age band across all 4 years: 22–40
• Multiplier: 1 week per year
• Qualifying years: 4
• Weekly pay used: the employee’s weekly pay, capped if above the statutory limit

Statutory redundancy pay: 4 × 1 week’s pay = 4 weeks’ pay (subject to the weekly cap)

Example 2: Employee Aged 45 With 10 Full Years’ Service

Here you need to think about how many years fell into each band.

Assume they started at age 35 and are now 45, with 10 full years’ service:

• Years aged 35–40: 6 years at 1 week per year
• Years aged 41–45: 4 years at 1.5 weeks per year

Statutory redundancy pay:

• 6 × 1 = 6 weeks’ pay
• 4 × 1.5 = 6 weeks’ pay

Total: 12 weeks’ pay (subject to the weekly cap)

Example 3: Employee With 23 Years’ Service

If the employee has 23 full years’ service, you only count 20 years for statutory redundancy.

You would still apply the correct age multipliers across those 20 years, but the remaining 3 years are simply not included in the statutory calculation.

A Quick “Statutory Redundancy Calculator” Checklist

When you’re sense-checking a redundancy payment calculation, ask:

• Have we confirmed at least 2 years’ continuous service?
• Are we counting only full years?
• Are we using a maximum of 20 years?
• Have we applied the correct age band multiplier for each year?
• Have we worked out “weekly pay” correctly and applied the statutory cap?
• Have we separated redundancy pay from notice pay and holiday pay?

Common Employer Mistakes When Calculating Redundancy Pay

Even careful employers get caught out by redundancy calculations - especially when it’s not something you do often.

Mixing Up Redundancy Pay With Notice Pay

Statutory redundancy pay is not a replacement for notice pay.

If the employee is entitled to notice (contractual or statutory), you generally still have to provide:

• paid notice worked, or
• payment in lieu of notice (if your contract allows it), plus
• their redundancy payment (if eligible)

Notice entitlements are a common area of dispute, so it helps to understand statutory notice pay and then cross-check what your contract says.

Forgetting Accrued Holiday Pay

When employment ends, employees are typically entitled to be paid for accrued but untaken statutory holiday (and any additional contractual holiday, depending on your terms).

This is separate from redundancy pay, and can materially change the “total cost” of the exit - particularly if redundancies happen partway through a holiday year.

Using The Wrong Weekly Pay Figure

Where an employee’s pay varies (for example, shifts, overtime, commission, variable hours), the “weekly pay” calculation can get technical.

If you use the wrong reference period or exclude pay elements incorrectly, you can underpay - which can create legal and relationship risk.

Assuming Everyone Gets Statutory Redundancy Pay

Eligibility generally requires 2 years’ continuous service. If someone has less, they may not be entitled to statutory redundancy pay - but you still need to deal with the termination lawfully (including correct notice and a fair process).

Failing To Keep Paperwork

If an employee challenges your figures, being able to show the workings (including dates, age-band breakdown, weekly pay method and caps used) makes it much easier to resolve quickly.

Redundancy Pay Is Only One Part Of A Lawful Redundancy Process

Redundancy payments matter - but for most small businesses, the bigger risk is often the process.

Even where redundancy is genuine, employers can face claims if the process is rushed, inconsistent or poorly documented. A few areas to keep front of mind:

Make Sure It’s A Genuine Redundancy Situation

A redundancy usually involves:

• your business closing or planning to close
• your workplace closing or relocating
• reduced need for employees to do work of a particular kind

If you’re removing a person rather than removing a role, that’s a red flag - and it’s where disputes can start.

Consultation Requirements (And Timing)

You’ll often need to consult with affected staff and discuss ways to avoid or reduce redundancies. If you’re making 20 or more redundancies at one establishment within 90 days, collective redundancy rules can apply and the stakes go up significantly.

It helps to understand redundancy consultation periods early, so you don’t promise timelines you can’t legally meet.

Selection Criteria And Fair Scoring

If you’re selecting from a pool of employees, you should use fair and objective criteria, apply them consistently, and keep records.

A documented approach like a redundancy scoring matrix can help reduce the risk of a “this was personal” allegation later.

Think About Suitable Alternative Employment

If you have other roles available, you should consider whether they could be suitable alternative employment (even if the role is a bit different). Not considering alternatives can increase risk.

Settlement Terms (If You’re Offering Enhanced Packages)

If you’re offering an enhanced redundancy payment in exchange for extra protections (like waiving claims), you’ll typically need a settlement agreement that meets the legal requirements for employees to validly waive statutory employment claims (including independent legal advice for the employee). The drafting and process are important - you want to avoid paying extra without getting the certainty you thought you were buying.

In some situations, you might document agreed exit terms in another format (for example, where you’re settling a non-employment dispute), but a deed on its own will not usually achieve a valid waiver of statutory employment rights. If you’re exploring an enhanced package, it’s worth getting advice before you propose terms or draft documents.

If you want to reduce risk and keep the process clean, getting Redundancy Advice early can be the difference between a manageable process and a costly dispute.

Key Takeaways

• Statutory redundancy pay is a legal minimum for eligible employees (usually those with at least 2 years’ continuous service) and is calculated using age bands, years of service (capped at 20), and weekly pay (subject to a statutory cap).
• A statutory redundancy pay calculator approach means breaking down each full year of service by the employee’s age during that year and applying the correct multiplier (0.5, 1, or 1.5 weeks).
• Redundancy pay is separate to other termination payments like notice pay and accrued holiday pay - make sure you’re not blending these together in your figures.
• Many redundancy disputes come from process issues (selection, consultation, documentation), even where the redundancy itself is genuine.
• Keep clear written records of how you calculated the payment and how you ran the process - it’s one of the simplest ways to reduce risk.
• If you’re offering enhanced terms or want extra certainty, get advice before you propose packages or draft exit documents.

Tax note: Redundancy pay can have different tax treatment depending on what the payment is for (for example, statutory/contractual redundancy pay versus notice pay or holiday pay). Some termination payments may be eligible for tax-free treatment up to certain limits, while others are usually subject to tax and National Insurance. Because the rules are technical, it’s sensible to check HMRC guidance or get advice when you’re costing an exit package.
