Calculator and documents for redundancy pay calculation

When you make an employee redundant, calculating their redundancy pay correctly is both a legal obligation and a matter of treating people fairly during what's probably the most difficult conversation you'll have as an employer. Getting the calculation wrong — underpaying, applying the wrong tax treatment, or missing a component — turns a stressful situation into a genuinely messy one.

This guide walks you through how to calculate both statutory and enhanced redundancy pay, handle the tax side properly, and avoid the mistakes we see most often. If your contract or handbook promises enhanced terms, you need to know how those work too.

Who qualifies for statutory redundancy pay?

Not every departing employee gets statutory redundancy. Your employee is entitled to it only if they tick all three boxes:

  1. Two years of continuous service — they've been with you long enough. There's no grace period; if they've got 23 months, they don't qualify.
  2. Their job is genuinely redundant — their role is disappearing, not them being managed out for performance issues or misconduct.
  3. They're an employee, not a contractor — this matters for the paperwork later.

There are edge cases. Employees who are dismissed for misconduct during notice, or who unreasonably turn down a suitable alternative role, can forfeit their entitlement. But the baseline is: two years in, role eliminated, employee status = yes, they get statutory redundancy.

For the legal detail, gov.uk publishes the official rules, and Acas has detailed guidance on redundancy that covers edge cases you might hit.

How to calculate statutory redundancy pay

The formula is more straightforward than it looks. You're multiplying three things together:

  • Years of service (capped at 20)
  • Weekly pay (subject to a statutory cap set by the government)
  • An age-based multiplier that changes depending how old the employee was during each year they worked for you

The age multiplier is where most people slip up, so let's be precise:

  • Aged under 22 at any point during a year of service: 0.5 weeks' pay per year
  • Aged 22–40 during a year of service: 1 week's pay per year
  • Aged 41+ during a year of service: 1.5 weeks' pay per year

Here's the important bit: you apply the multiplier year by year, not all at once. If an employee was 21 when they started, turned 22 in year three, and is now 45, they don't get 1.5 weeks per year for their whole service. You calculate each year individually based on their age during that year.

Worked example

Let's say you're making redundant a 48-year-old who's been with you 14 years. Their weekly pay (gross, before deductions) is £520, which is below the statutory cap.

Their age profile:

  • Started age 34, so years 1–7 (age 34–40): 1 week's pay per year = 7 weeks
  • Years 8–14 (age 41+): 1.5 weeks' pay per year = 10.5 weeks
  • Total: 17.5 weeks of pay
  • Amount: 17.5 × £520 = £9,100

The statutory cap on weekly pay is updated each year. Check the current cap on gov.uk — if your employee's actual weekly pay exceeds it, you use the capped figure instead.

Calculating weekly pay for variable earners

If your employee has a fixed salary, weekly pay is their gross salary divided by 52.

If they earn variable pay — overtime, commissions, shift allowances, bonuses that form part of normal pay — you need to average it out. Take their gross pay over the 12 weeks before the redundancy notice was given, then divide by 12 to get the weekly figure. This catches employees who've had a particularly high (or low) recent month and gives a fairer picture. This is the same principle you'd apply to calculating holiday entitlement for part-time and irregular workers.

Don't include bonuses or commissions that are discretionary or don't form part of their regular earning pattern.

Enhanced redundancy: going beyond the statutory minimum

Many employers offer redundancy terms that exceed the statutory formula. This might be:

  • A higher number of weeks per year (maybe 1.5 weeks per year at all ages, instead of the tiered approach)
  • Removing the statutory cap on weekly pay (so a higher-earner gets their actual salary in the calculation)
  • A flat lump sum on top
  • A combination of all three

Enhanced terms might live in your employment contract, company handbook, a collective agreement with a union, or even a decision made at the time of the redundancy. Whatever the source, the key rule is: be consistent. If you offer different enhanced packages to different employees in the same redundancy round, you're creating discrimination risks and fairness problems. Document the basis for any differences.

Tax treatment — the bit that trips people up

This is where many small employers get tangled. The tax rules for redundancy are different from normal pay.

Statutory redundancy pay is tax-free. No income tax, no employee National Insurance. It's a clean payment.

Enhanced redundancy pay gets more complex. In the UK, there's a combined tax-free threshold of £30,000 for statutory plus enhanced redundancy combined. Anything above £30,000 is subject to income tax (but not employee National Insurance, which is a small mercy).

Here's the trap: notice pay is always taxable as ordinary earnings — it's not part of the £30,000 threshold. If your employee's contract includes a PILON clause (payment in lieu of notice), that gets taxed normally. Don't accidentally lump it in with redundancy pay and treat it as tax-free.

When you process the final payment through your payroll system:

  • Code statutory redundancy as tax-free
  • Code enhanced redundancy up to the threshold as tax-free
  • Code anything above the threshold as taxable pay at the employee's marginal tax rate
  • Code notice pay (worked or PILON) as normal taxable earnings
  • Code any accrued holiday pay as taxable

If your payroll software doesn't handle these distinctions — or worse, if you're doing it in a spreadsheet — you're vulnerable to getting the tax wrong and creating a mess for the employee at tax return time.

Other payments that go into the final pay packet

Redundancy pay isn't the only thing the departing employee receives. The total final payment usually includes:

Accrued holiday — any days they've earned but haven't taken. This is taxed as normal earnings.

Pay in lieu of notice — if they're not working their notice period, they get paid for it. Taxed as normal pay.

Outstanding salary or wages — anything unpaid up to their last day. Taxed normally.

Bonus or commission — if they're entitled to it for work already completed, check your scheme rules. Many bonuses include "not eligible if you've resigned or been made redundant" clauses.

When you're settling a leaver's final pay, keep each element separate in your records. Mixed together in one figure, they're a nightmare to unpick if someone queries the tax treatment.

Common mistakes and how to avoid them

Using net pay instead of gross — statutory redundancy is calculated on gross pay (before tax and deductions), subject to the cap. If you accidentally use net take-home, the calculation is wrong.

Forgetting the age multiplier changes year by year — the employee's age matters for each individual year of service. Don't apply one multiplier to their whole service.

Ignoring the statutory cap — even if an employee earns £80,000 a year, the statutory calculation uses the capped weekly figure. Enhanced terms can exceed the cap, but statutory doesn't.

Mixing up redundancy pay and notice pay for tax purposes — redundancy can be tax-free (up to £30k), notice is always taxable. They're treated differently.

Assuming salary-only employees have no variable pay — check for regularly paid shift premiums, standby payments, or other add-ons that form part of normal pay. You need to include those in the weekly pay calculation.

Not keeping records — document the calculation as you go. Service dates, age at each year, multiplier applied, weekly pay figure, enhanced terms, everything. If the employee or HMRC asks how you got to the number, you need to show your working.

Frequently Asked Questions

Q: Do contractors get redundancy pay? A: No. Redundancy pay is an employment law right, and it only applies to employees. If someone's a contractor or self-employed, there's no statutory redundancy entitlement. Your agreement might include a termination payment, but that's a separate matter.

Q: What if the employee has taken unpaid leave or a sabbatical? A: Continuous service is interrupted by significant unpaid leave. A few days off here and there don't break it, but a months-long sabbatical or extended unpaid leave might. Check your employment records carefully. Acas guidance covers edge cases like this.

Q: Can I use average pay over a longer period than 12 weeks for variable earners? A: The statutory rule is 12 weeks or whatever reference period your employment contract specifies. If the contract says something different, use that. If you don't have a clause, 12 weeks is standard.

Q: What if the employee is already on notice for a different reason — say, they've resigned — and then I make their role redundant? A: If they've already handed in notice, the redundancy situation is legally murky. Get advice from Acas or an employment lawyer. You may owe redundancy pay, may not, depending on the exact timeline and circumstances.

Q: Does redundancy pay count toward their National Insurance record? A: No. Only tax applies (up to the £30k threshold). Employee National Insurance isn't deducted from redundancy pay.

Q: If I offer enhanced redundancy, do I have to offer it to everyone? A: Not necessarily, but you must be consistent within a redundancy exercise. If five people are being made redundant at the same time, they should get the same enhanced terms unless there's a documented, legitimate reason for a difference. Inconsistency opens the door to discrimination claims.

Q: What if the employee disputes the calculation after I've paid them? A: Once you've paid them out and they've accepted the settlement, they can't come back asking for more redundancy pay. That's why getting it right the first time matters. If the calculation is genuinely wrong — you used the wrong multiplier or forgot a year of service — they could challenge it, but prevention is better than cure.

Q: How is this different from other statutory payments like sick pay? A: Different statutory payments have different rules. Statutory sick pay, maternity pay, and redundancy all have their own formulas and tax treatment. Redundancy is distinct because it's about service and age, not eligibility for time off.

The bottom line

Redundancy pay has specific, non-negotiable rules. Use the right formula — years of service, age-based multiplier, capped weekly pay. Apply the correct tax treatment: statutory redundancy is tax-free, enhanced redundancy is tax-free up to £30,000 combined, anything above that is taxable, and notice pay is always taxable. Document everything. Process it through your payroll system to avoid errors.

Most importantly: be fair and transparent. Redundancy is already difficult; making the financial side clear and honest reduces disputes and shows your departing employee that you've treated them with respect.
