How is the time value calculated?

We value commute time at 70% of your hourly wage (stress factor reduction compared to paid work) to reflect that commute time is less productive. This is a conservative estimate based on UK Office for National Statistics commuting research.

Why do energy costs increase when working from home?

Heating your home during the day uses more energy, though insulation significantly reduces this. We estimate 15% heating increase (8% with insulation) plus modest electricity usage (£2.50/day). Your actual costs vary by region, property age, and heating source.

Should I factor in employer commute contributions?

Many employers offer travel card discounts or subsidies. The calculator shows your full costs—if your employer covers part, subtract that amount from the calculated transport savings to see your true net benefit.

What is the break-even analysis telling me?

This shows the minimum WFH days needed for your total savings (transport + food - energy) to exceed zero. If your break-even is 2 days/week and you WFH 3 days, you're financially ahead before considering time value.

Are there other benefits to WFH I should consider?

The calculator focuses on financial impact and time value. Consider also: mental health, work-life balance, productivity, collaboration, career progression, and employer expectations. This tool should inform but not decide your working arrangement.

Follow these steps to get the most from this tool

Transport mode selection: Car (most expensive: fuel + insurance + parking + depreciation), Train (moderate: fixed ticket + time), Bus (cheapest: similar to train), Underground (London-specific, moderate cost but good speed). Each has different cost structure and time implications. Choose your typical mode; multi-modal commutes (e.g., drive to station, then train) should use blended rates—ask calculator for help with multi-step commutes.

Distance or cost entry: If you know exact distance (e.g., home to office 15 miles): enter miles. If remote (no office), enter 0. Tool calculates commute time and cost automatically. If commute cost varies (London Travelcard £160+/month vs Bristol £80/month), enter your actual monthly ticket cost. Override default prices with real-world costs for accuracy.

Parking cost if applicable: Car drivers in cities: parking at office £5-15/day typical in London/Manchester, sometimes free in suburban areas. Enter your actual cost. This is often overlooked in WFH ROI but can be £50-150/month savings alone (better than any other factor).
