Jar Savings Calculator

A tip jar calculation helps estimate earnings from a shared tip pool — common in cafes, bars, and restaurants where tips collected during a shift are divided among staff.

Simple equal split: Amount per person = Total tips / Number of staff

Weighted split (by hours worked): Amount per person = Total tips × (Person’s hours / Total hours worked by all staff)

Worked example — equal split: Tip jar total after Saturday shift: £185 Staff working: 4 people Each person receives: £185 / 4 = £46.25

Worked example — weighted by hours: Tip jar: £240

• Alice worked 8 hours
• Bob worked 6 hours
• Carol worked 4 hours Total hours: 18

Alice: £240 × (8/18) = £106.67 Bob: £240 × (6/18) = £80.00 Carol: £240 × (4/18) = £53.33 Total: £240.00 ✓

Tronc schemes (UK): A tronc is a formal system for distributing tips and service charges in hospitality. When managed by a troncmaster (independent from the employer), tronc distributions are exempt from National Insurance contributions — saving both employees and employers money.

The Tipping Act (UK, October 2024): The Employment (Allocation of Tips) Act 2023 now legally requires employers to pass 100% of tips and service charges to workers. Employers cannot deduct card processing fees or administrative costs from tips. Workers can request a statement of tip payments.

Taxation: Tips are taxable income. Cash tips should be declared on self-assessment tax returns. Tips processed through payroll are subject to PAYE. Tronc distributions from qualifying schemes are subject to income tax but not NI.
