Inna Protein Cost Breakdown: What You Really Pay Per Serve, Bag vs Bundle vs Subscription

Protein powder prices are hard to compare by the bag. Bags come in different sizes, serving sizes vary, and bundles, subscriptions and shipping thresholds all move the real cost. The only fair comparison is cost per serve, and ideally cost per gram of protein. This breakdown does that math for every way to buy Inna Protein, an Australian faba bean protein powder brand, using its published Australian dollar prices.

The baseline: one 750g bag

Every Inna protein powder flavour comes in a 750g bag for $59 AUD. Inna lists 25 serves per bag, so one serve is 30g.

• Cost per serve: $59 / 25 = $2.36
• Protein per serve: 24.3g for the flavoured powders, 25.3g for unflavoured
• Cost per gram of protein: about 9.7 cents (flavoured) or 9.3 cents (unflavoured)

Keep $2.36 as the reference point. Everything below is measured against it.

Subscribe & Save

Inna's subscription saves 15% on every order, and you can skip, cancel or swap at any time.

• One bag on subscription: $59 x 0.85 = $50.15
• Cost per serve: about $2.01

That is a 35 cent saving on every serve without buying in bulk. For someone using one bag a month, it adds up to roughly $106 a year.

Multi-bag specials

• 2 Pack Special: $108 for 50 serves = $2.16 per serve
• 3 Pack Special: $139 for 75 serves = $1.85 per serve
• Stock-Up Bundle (six 750g bags): $249 for 150 serves = $1.66 per serve

The Stock-Up Bundle is the lowest per-serve price in the range, about 30% below a single bag. The 3 Pack sits in a useful middle ground: a meaningful saving, and enough volume to clear the free-shipping threshold.

The shipping factor

Within Australia, Inna ships free on orders over $120. Below that, live Australia Post rates are calculated at checkout. That changes the comparison:

• A single bag ($59) and the 2 Pack ($108) both sit under $120, so shipping is added on top.
• The 3 Pack ($139) and the Stock-Up Bundle ($249) qualify for free shipping.

For buyers who are not subscribing, the 3 Pack is often the smartest order: it clears free shipping and drops the serve price to $1.85.

International orders to New Zealand, Singapore, the United States and Malaysia are charged at live carrier rates, and local import duties may apply, so overseas buyers should check total landed cost at checkout.

Bundles with other products

Several bundles mix protein with Inna's other products. To compare them fairly, it helps to know the single-item prices: protein pancake mix is $14.50 per 200g pack, and Creatine Monohydrate is $28 for 300g.

• Performance Bundle ($99): two 750g bags plus 300g creatine. Bought separately that is $146.
• Foodie Bundle ($89): two bags plus one pancake mix. Separately, $132.50.
• Complete Bundle ($149): three bags, two pancake mixes and 300g creatine. Separately, $234.

If you already planned to buy creatine or pancake mix, these bundles are strong value; the Performance Bundle in particular includes two bags and creatine for less than the 2 Pack plus a creatine tub bought separately. If you would not use the extras, the plain multi-bag specials are cheaper per serve of protein.

Trying before committing

Sample sachets cost $5 each for a single 30g serve. Per serve they are the most expensive way to buy, but they cost far less than a bag in a flavour you end up disliking. The Starter Bundle ($26) includes six 30g sachets, one of every flavour, and the Travel Pack ($39) gives you ten sachets of your choice.

Adding a discount code

At the time of writing, code DUYNGUYENKHAC-PPP10 takes 10% off storewide. Applied to a single bag, that brings the serve price to about $2.12. Applied to the 3 Pack, it brings the order to $125.10, about $1.67 per serve, and still above the $120 free-shipping line. Whether a code combines with subscription pricing or specific bundles is decided at checkout, so confirm the final price there.

How it compares with buying less often

A useful way to think about the options is by how many serves you use a month. At one serve a day, you use about 30 serves, a little over one bag, a month. Over a year, that is about 15 bags. Buying single bags at $2.36 a serve costs around $860 a year; the same volume via subscription at about $2.01 costs around $735; and buying Stock-Up Bundles at $1.66 costs around $605. At a few serves a week, a single bag lasts two months, and the subscription or a 2 Pack makes more sense than six bags sitting in the pantry.

Check the best-before date and storage space before buying in bulk. Inna sells a $12 bamboo storage canister for decanting, but unopened pouches stored in a cool, dry cupboard are the simplest option.

Cost-per-serve summary

• Sample sachet: $5.00
• Single bag: $2.36
• 2 Pack: $2.16
• Single bag on subscription: about $2.01
• 3 Pack: $1.85 (free shipping in Australia)
• Stock-Up Bundle: $1.66 (free shipping in Australia)

Conclusion

For regular users, the cheapest options are the Stock-Up Bundle or a subscription, depending on whether you prefer to buy in bulk or spread the cost. Occasional buyers get the best balance from the 3 Pack, which clears free shipping. Bundles with creatine or pancakes make sense only if you would buy those items anyway. And if you have not tried the product yet, spend $5 to $26 on samples first.
