Referral Bonus Calculator

Thinking of rewarding customers who send you work? Find out how much you can afford to give, based on what a referred customer is actually worth to you over time.

The short version

A referred customer arrives already trusting you, so they cost far less to win than one from an advert. Work out the profit you make from them over the jobs you expect, and that tells you how much a referral bonus can be before it stops paying. A sensible rule is to keep a bonus to around a quarter of that profit.

Comfortable bonus = Profit per job × jobs from the customer × 25%

Referrals are the cheapest customers you will ever win

Someone who comes to you on a recommendation has already been sold. They trust you before the first call, they are less likely to haggle, and they tend to be easier to deal with. Compare that with a customer from an advert, who you have paid to find and then still had to convince.

If a referred customer is worth $720 in profit over a few jobs, paying $50 to the person who sent them is a bargain. Paying $700 would not be.

Why a bonus is not the same as a bribe

Most people refer you because you did good work, not because of a reward. A small thank-you simply makes it more likely they remember to mention you, and shows you noticed. It does not need to be big to work.

Keep the bonus well inside what you can afford

The break-even bonus is the most you could ever pay before you make nothing. You never want to be near it. Keeping a bonus to roughly a quarter of the profit leaves you with most of the money and the customer, and a bonus paid only when a referral turns into a job means you never pay for nothing.

Questions tradespeople ask

How much should I pay for a customer referral?
Far less than the profit you expect from the new customer. Many trades keep it to around a quarter of that profit, and some give a small fixed amount or a discount on the referrer's next job. The calculator shows where your own limit sits.
Should I pay the bonus before or after the job?
After. Pay it once the referred customer has become a paying job, so you never spend money on a referral that goes nowhere.
Is cash or a discount better as a reward?
Either works. A discount on their next job also brings the referrer back to you, while cash or a voucher feels more like a clear thank-you. Choose whichever you can offer consistently.
How do I know how many jobs to expect from a referred customer?
Look at your own repeat customers. Roughly how many jobs does a typical new customer give you over a few years? If you are unsure, start with the first job only and add repeat work once you have seen it happen.
Do referral bonuses actually get more referrals?
Often they do, mostly by prompting people to remember you at the right moment. The bigger driver is still doing good work and asking, so treat the bonus as a thank-you rather than the whole plan.
