The working maths behind paid media decisions, built for Australian businesses. GST handled properly, everything in AUD, and the calculations shown rather than hidden.
The return on ad spend an order has to produce before it makes you a cent. Enter your order value, cost of goods, fulfilment and fees, and see your floor and your target side by side.
How much budget it actually takes to hit a lead or sales target, or what a fixed budget will realistically return. Works in both directions from the same three numbers.
Four questions and you get a recommended monthly split across Google Search, Meta, retargeting and local, weighted for your industry, your goal and how long your customers take to decide.
The most you can pay for an enquiry, a qualified lead and a closed sale without going backwards. Built for service businesses that sell off leads rather than a checkout.
Enter whatever you have from a campaign report and get every derived metric at once: CTR, CPC, CPM, conversion rate, CPA, ROAS, ACOS and average order value.
What a customer costs to acquire, what they are worth over their life, and how many months it takes to get the acquisition cost back. The argument for and against buying growth.
Build tagged campaign URLs that report cleanly. Platform presets for Google, Meta, LinkedIn, TikTok and email, with the dynamic parameters filled in for you.
These cover the questions that come up most often. If something you need is missing — ad spend waste, in-house versus consultant cost, a channel-specific model — say so and it gets built next.
Request a calculatorThese are the same calculations used when setting targets on a real account. They are deliberately transparent, so you can check the working rather than trust a number.
Pull the numbers from your accounting system, not from memory and not from an industry benchmark. A calculator fed with estimates returns an estimate, and the further those inputs sit from reality, the further the answer will too.
Every tool shows the maths behind it on the page. If a result looks wrong, work through the formula with your own figures. Where the calculator and your accounts disagree, your accounts are right.
These are estimating tools, not advice. Reconcile anything you plan to act on against your own records, and run material decisions past your accountant or adviser before changing budgets or bid targets.
Every tool on this page is an educational estimating tool, not advice. The results are illustrative only and must not be relied upon as financial, accounting, taxation, investment, legal or professional advice. They do not take your objectives, financial situation or particular needs into account.
Results depend entirely on the figures you enter and on simplified models that exclude many real-world variables, including fixed costs, tax treatment, seasonality, lifetime value, attribution differences and product-level variation. Outputs are not forecasts, projections, guarantees or predictions of performance. Returns vary by industry, and any figures shown on this site are illustrative of well-optimised accounts rather than typical or expected results.
Verify independently. Before making any business, budgeting or bidding decision, reconcile these figures against your own accounting records and seek advice from a qualified accountant, tax agent or licensed financial adviser familiar with your circumstances.
No warranty. These tools are provided on an "as is" and "as available" basis. To the maximum extent permitted by law, Paid Media Plus makes no representation or warranty as to the accuracy, completeness, reliability or fitness for purpose of any calculator or its output, and accepts no liability for any loss, damage or cost arising directly or indirectly from its use or from reliance on any figure it produces. Nothing here excludes, restricts or modifies any guarantee, right or remedy you may have under the Australian Consumer Law or any other law that cannot lawfully be excluded.
Each calculator also carries its own disclaimer covering the specific limitations of its model. Use of these tools is governed by our terms of use and privacy policy. All figures are in Australian dollars.
A calculator tells you what your account should be doing. A free audit tells you what it is actually doing, and the three highest-impact fixes you can make this week.
