A referral costs the company 2,433. An agency costs 12,000

Referral schemes are usually framed as a perk for employees. Run the numbers from the employer's side and they are one of the cheapest hiring channels in existence — which is also the argument for why the bonus attached to them is generally too small.

How it works

  • Prices a referral from the referrer's side: the bonus, weighted by how often a referral actually converts, less the hours it costs you.
  • Prices the same hire from the company's side and compares it against a recruitment agency fee.
  • Shows how many referrals you need to make before one expects to pay out.
expected value per referral = bonus × conversion rate − (hours × your hourly rate)

company cost per referred hire = bonus + (hours to source one hire × internal hourly rate)

agency cost = salary × agency percentage

Worked example

A 2,000 referral bonus, three hours of your time per referral, one in five referrals resulting in a hire, on a 60,000 role with a 20% agency alternative.

  1. your time: 3 h × 28.85 = 87 per referral
  2. expected value: 2,000 × 20% = 400, net 313 per referral
  3. five referrals per hire, so 15 hours of internal time = 433
  4. company cost per referred hire: 2,000 + 433 = 2,433
  5. agency fee: 60,000 × 20% = 12,000

The referral route costs the company 2,433 against 12,000 through an agency — 4.9 times cheaper. The employee doing the referring captures 2,000 of a roughly 9,600 saving.

Reading the result

  • That split is the case for asking about the bonus rather than accepting it. A company saving nearly 10,000 per referred hire has considerable room, and referral bonuses are among the easiest policies to get changed because the saving is so easy to demonstrate.
  • Most schemes pay only after the hire stays three or six months, and some pay in instalments. Money conditional on someone else's decisions a year out is worth less than the headline suggests.
  • The expected value only works if you refer people who might genuinely be hired. Referring weak candidates lowers your conversion rate, and after a few misses your recommendations stop carrying weight — which costs more than the bonus.
  • Referred hires tend to stay longer than agency hires, so the real gap is wider than the fees alone. That durability, not the fee saving, is usually why the scheme exists.

Common questions

Is referring people actually worth my time?
At these numbers, 313 expected per referral for three hours is roughly 104 an hour — well above most people's salary rate. It stops being worth it if your conversion rate is low, which is another reason to refer selectively.
Can I negotiate a larger referral bonus?
For a hard-to-fill role, often yes. The comparison to make is not against the current bonus but against what the company would otherwise pay an agency — a case that is unusually easy to put in writing.
