Estimate savings from a remote job.
Remote working saves on the two costs that only occur when you go in — the commute and bought food — and adds a smaller cost in heating, electricity and equipment at home. Netting them shows the real figure, which is typically substantial: avoiding three office days a week at 21 a day is nearly 2,900 a year gross, against a few hundred in additional home costs.
Net remote working saving
Gross saving = (commute + lunch) x days avoided x 46 weeks; extra home cost = monthly x 12; net = gross - extra home cost
Typically 30-60 a month in heating and electricity, more in winter and in poorly insulated homes. Some jurisdictions allow a tax deduction or a flat allowance for this, which reduces the net cost further.
Compare the net saving grossed up for tax. A 2,500 net annual saving is roughly equivalent to 3,400 of gross salary, so a remote role paying 2,000 less can still leave you better off.
One-off equipment costs for a proper desk and chair, and the value of the commuting time recovered. The first reduces the first-year saving; the second is usually worth more than the cash.
