Jar Savings Calculator
Calculate your savings from a daily tip jar or coin-saving habit.
Set a contribution amount, frequency, and time period to project your total savings.
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.
