## Core Calculators

- [Pro Rata Salary Calculator](https://easyprorata.com/salary-calculator/): Converts full-time gross salary to part-time pro rata annual, monthly, weekly, bi-weekly, and hourly pay. Calculates Full-Time Equivalent (FTE) ratios for 1 to 5 working days per week or custom hours.
- [Pro Rata Holiday & Annual Leave Calculator](https://easyprorata.com/leave-calculator/): Calculates statutory leave proration under UK 5.6-week rules (capped at 28 days) and Australian 4-week National Employment Standards (NES), with mid-year starter/leaver adjustments.
- [Prorated Rent Calculator](https://easyprorata.com/rent-calculator/): Computes tenancy rent proration for mid-month move-ins and move-outs using actual days in month, 30-day banker's month, or annual 365-day conventions.

## Mathematical Formulas & Reference Standards

- **Full-Time Equivalent (FTE) Ratio**: `FTE = Contracted Weekly Hours / Full-Time Benchmark Hours` (e.g. 22.5 / 37.5 = 0.60 FTE).
- **Pro Rata Annual Salary**: `Pro Rata Salary = Full-Time Annual Salary × FTE`.
- **UK Statutory Leave (5.6 Weeks)**: `Annual Leave Days = Working Days Per Week × 5.6` (capped at 28 days per year for full-time workers under Regulation 13 & 13A of the UK Working Time Regulations 1998).
- **Australian Annual Leave (NES)**: `Annual Leave Weeks = 4 weeks × FTE` (under Section 87 of the Fair Work Act 2009; 5 weeks for eligible shiftworkers).
- **Prorated Rent (Actual Days Method)**: `Prorated Rent = (Monthly Rent / Days in Current Month) × Days of Occupancy`.
- **Prorated Rent (30-Day Banker's Month)**: `Prorated Rent = (Monthly Rent / 30) × Days of Occupancy`.
