Benefits are priced by the employer, which is why headline value misleads

Two different numbers

Every benefit has a cost to the employer and a value to you, and there is no reason for those to be equal. That gap is the entire reason employers offer benefits rather than simply paying the equivalent in cash: where the gap runs in your favour, both sides gain, and where it runs the other way you are being sold something at a markup.

The gap comes from a few reliable sources. Employers buy in bulk and get prices an individual cannot. Some forms of compensation receive different tax treatment from salary, though how and whether varies completely by country. And some benefits are priced on the assumption that most people will not use them, which is where the value proposition quietly inverts.

Where the gap favours you

Anything bought at group scale that you would otherwise buy alone tends to be a genuine gain. Group medical and life cover are the clearest cases, because individual pricing depends on individual risk assessment while group pricing does not, so the benefit is worth most to precisely the people who would find it most expensive to buy themselves.

Employer pension or retirement contributions are usually the largest item on the list by a distance, and are consistently the most ignored by people early in their careers. This site is about how compensation is decided rather than what to do with money afterwards, so the relevant point here is simply that a contribution is part of what you are paid, and comparing two offers without including it compares the wrong numbers.

Training, professional qualifications and conference budgets have a different kind of asymmetry: they cost the employer a modest amount and can raise your market value permanently. In the first five years that is often the most valuable line on the whole benefits page, and it is the one most often left unspent.

Where the gap runs against you

Anything you would not have bought at its cash cost is worth less than its headline. Gym memberships, subscription boxes, discount schemes for shops you do not use, an on-site perk you use twice a year. These appear on the list at their retail value and are often supplied at a fraction of it, which flatters the total.

Then there is the category that only pays out under conditions you should read carefully. An insurance-style benefit with a long qualifying period, exclusions for anything pre-existing, or a payout defined as a proportion of something other than your actual salary can be worth substantially less than the name suggests. This is not usually deception; it is what makes the group price affordable. But it means the document matters more than the bullet point.

Equity is the hardest case, because its headline value is a projection rather than a fact. Vesting schedules, cliffs and what happens if you leave are all decided by documents you may not see until after you accept, and in a private company there may be no way to convert it to cash for years, if at all.

Flexibility is compensation even though it has no price

Remote or hybrid working, control over your own hours, and genuine tolerance for a life outside work do not appear on any total-compensation statement, and for many people they are worth more than any line that does. They also have a cost to the employer that is real but hard to quantify, which is why they get traded away in negotiations more readily than cash.

The catch is that these are the least contractually secure part of any package. Policy changes, a new senior hire arrives with different views, and an arrangement that was a major reason you accepted disappears without breaching anything. It is worth knowing which parts of your package are contractual and which are current practice, because the two behave very differently under pressure.

Comparing two packages honestly

The only sound method is to convert everything to what it is worth to you specifically, not what it is worth on average. Employer pension contribution: count it in full. Medical cover: count what you would otherwise pay, or nearly zero if you would not buy it. Perks you will not use: zero, however impressive the list.

And be careful with any total-compensation figure supplied by the employer, since those are assembled from employer costs and typically include everything at full retail. It is not dishonest, but it is the number most favourable to them, and the amount that reaches your bank account each month is a different and much smaller thing. Tax treatment in particular varies so much by country and by scheme that anything material is worth checking with someone qualified where you live rather than reasoning about from first principles.
