TUPE Transfer Calculator
TUPE transfer financial impact.
Calculate the financial impact of a TUPE transfer on your pension, holiday entitlement, and benefits based on your current salary.
What this tool does
This calculator models the financial impact of a TUPE transfer by estimating the annual benefit gap between your current and new employment terms. It combines three separate loss calculations: pension contribution changes (based on the difference in percentage rates applied to your salary), holiday entitlement differences (valued at your daily rate), and any changes to other monetary benefits. The result shows the total annual value lost across these areas. Pension percentage changes and salary level drive the largest impacts. A typical scenario might involve comparing terms when moving to a new employer under transfer rules. The calculation assumes a standard working year of 240 days and treats all benefit changes as direct financial equivalents; it doesn't account for non-monetary benefits, future salary growth, or employment security factors.

TUPE (Transfer of Undertakings Protection of Employment) protects employees during business transfers (acquisitions, outsourcing). Salary and most benefits must transfer. But pension provisions can change (auto-enrolment minimum protected, but enhanced employer contributions can reduce). This tool quantifies post-TUPE benefit changes.
50k salary, current 5% pension vs new 3%: 1,000/year pension loss. 28 days holiday vs new 25: 625/year holiday value lost. 1,500 other benefits lost. Total annual benefit loss: 3,125 = 6.25% effective salary cut. Significant for someone whose employer is changing through TUPE.
TUPE rights: salary protected, contractual benefits protected, terms and conditions broadly protected. Not protected: future pay rises (new employer's structure applies), pension above auto-enrolment minimum, share schemes, discretionary bonuses. Significant material changes within 12-24 months can be challenged. Get legal advice if facing TUPE - your case may be stronger than you think.
Run it with sensible defaults
Using current salary of 50,000, current pension of 5%, new pension of 3%, current holiday days of 28, the calculation works out to 3,125.00. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Current Salary, Current Pension %, New Pension %, Current Holiday Days, and New Holiday Days — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
How the math works
Pension loss = salary × pension diff. Holiday loss = (salary/240) × days lost. Benefits loss = current - new. Total = sum.
Using this in pay negotiations
Knowing the exact figure behind a headline rate gives you specific numbers to anchor to in conversations about pay. "The difference is £X per month after tax" lands harder than "a couple of grand a year". Concrete numbers move decisions.
What this doesn't capture
Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
££50,000 pension 5%→3%, holidays 28→25 = 3,125.00.

Sources & Methodology
Methodology
The calculator computes total financial impact by measuring three distinct components of change. First, it calculates pension impact by multiplying annual salary by the percentage-point difference between current and new pension contributions. Second, it models holiday value by dividing annual salary by 240 (treating this as a standard working-day denominator) and multiplying by the difference in holiday entitlement days. Third, it calculates the change in other benefits as the simple difference between current and new benefit values. These three components are summed to produce the overall financial impact figure. The model assumes a linear relationship between salary and holiday value, treats all pension percentages as constant, and does not account for tax treatment, National Insurance implications, or how changes might interact with pay progression.
