Holiday Pay Rights & Calculator (2025 Edition)

You’re probably owed money. Most people are - they just don’t know it.

Holiday pay errors are one of the most common ways employers quietly underpay staff. Wrong calculations. Missing overtime. Commission not included. Bank holidays counted incorrectly. Part-time workers getting shorted.

And here’s the thing: they’re not always doing it on purpose. The rules are genuinely complicated. But that doesn’t mean you should lose out.

This guide + calculator gives you:

• Your exact holiday entitlement under 2024/2025 UK regulations

• A simple calculator to work out what you’re actually owed

• How to spot the most common underpayment tricks

• What counts towards holiday pay (clue: it’s more than just basic salary)

• The step-by-step process to claim back any shortfall

• How far back you can claim (it might be more than you think)

Why this matters:

Even small weekly shortfalls add up. If you’ve been underpaid by £20 a week for three years, that’s over £3,000 sitting in your employer’s pocket. Stop guessing. Calculate what you’re owed.
