Bonus stacking math that actually makes sense

Quick answer

Bonus stacking only works when the maths is defensible. If a buyer can sniff out that your 'bonus value' was pulled out of thin air, the entire offer collapses. Real bonus maths means each bonus has a price you could actually charge for it elsewhere, the bonuses solve discrete problems, and the total feels generous without crossing into 'this is too good to be true' territory.

The psychology

Buyers don't trust round numbers. £500 of bonuses feels made up. £477 of bonuses feels itemised. The brain reads precision as evidence that someone actually counted. This is the same reason £19.97 outsells £20 — the unfinished number signals 'this is the real number,' not 'this is the marketing number.'

The second principle is discrete problem mapping. If all your bonuses solve the same problem the main offer solves, they feel redundant. If each bonus solves a different friction point — getting started, staying motivated, troubleshooting, levelling up — the stack feels like a complete system. Buyers don't want bonuses; they want completeness.

Headline: The £597 Course That Includes £441 of Bonuses

Primary text:
Main course: 8 modules, 47 lessons (£597)

Bonus 1 — Quick-Start Audit (£97): a worksheet you fill out in 20 minutes that tells you which module to do first, so you don't waste time on lessons you don't need yet.

Bonus 2 — Templates Pack (£127): the 14 spreadsheets, scripts, and email templates I built for my own clients. Copy, paste, edit.

Bonus 3 — Office Hours (£197): a live group call every Wednesday for 8 weeks where I answer questions on camera. Recordings included.

Bonus 4 — Lifetime Updates (£20/year): every time I refresh the course, you get the new version. Forever.

Bonus total: £441
Course + bonuses: £597
You pay: £597 (the bonuses are included free)

Why it works

Notice what's NOT happening here. There's no fake value inflation — the course is £597, you pay £597, the bonuses are framed as free additions. That feels generous without feeling fishy. Each bonus targets a specific objection: 'where do I start' (audit), 'I don't have time to build assets' (templates), 'what if I get stuck' (office hours), 'will this go stale' (lifetime updates). The £441 number is also psychologically smart — it's specific (not £450), and it's smaller than the main course price, which is a believability cue that says 'these aren't bigger than the thing you're buying.'

FAQs

Should bonus value be more or less than the main offer value?

Less, in most cases. If the bonuses are worth more than the main thing, buyers wonder what they're actually paying for.

How do I price bonuses without being dishonest?

Use the price you would charge if you sold the bonus separately, even if you don't sell it separately today. 'If I built a separate course on this, I'd charge X' is honest as long as X is reasonable.

What's the right bonus count?

Three to five. Two feels stingy, six feels overwhelming. If you have more, group them — 'Bonus 4: the productivity pack — 12 templates, 4 SOPs, and 3 calculators' counts as one.

Can I add bonuses post-purchase?

Yes — surprise bonuses lift retention. Add one in week two of access; it makes the buyer feel they got more than they paid for and reduces refund requests.

How often should I refresh bonuses?

When your control ad fatigues. A new bonus is the easiest way to give an offer a second wind without changing the core product.
