CRO Calculator
Quantify the revenue impact of lifting your conversion rate. Adjust the inputs to see how a small lift in conversion translates to monthly and annual revenue gains.
Your Inputs
Projected Results
These projections are estimates based on your inputs. Real CRO results depend on test design, statistical significance, and which page in the funnel you optimise. Most CRO sprints deliver 20–40% lift in conversion rate; flagship redesigns sometimes achieve more.
How to Use This Calculator
CRO is the highest-leverage marketing investment most websites can make. Five inputs determine whether the spend pays back.
Monthly Website Traffic
Total monthly visitors across all channels. Get this from GA4 (Reports → Acquisition → Traffic acquisition). CRO works best with at least 5,000 monthly sessions to a target page — below that, statistical significance takes too long.
Current Conversion Rate
The percentage of visitors who complete your goal action. Get this from GA4: Conversions ÷ Sessions over the last 90 days. Australian benchmarks: e-commerce 1–4%, SaaS 2–5%, lead-gen 3–8%, local services 5–15%.
Target Conversion Rate
Realistic CRO sprints lift conversion 20–40% (relative). Major redesigns or funnel rebuilds can deliver 60–100%. Anything beyond +100% is rare and usually depends on fixing a specific broken element (e.g., a 5-step form collapsing to 1 step).
Average Order Value
Revenue per conversion. For e-commerce, use AOV from your platform. For lead-gen, multiply average customer value × close rate. Tracking lifetime value over 12 months meaningfully changes whether a CRO investment pays back.
CRO Investment
Total cost of the project — research, design, copywriting, development, and A/B testing infrastructure. Australian CRO sprints typically cost $5,000–$25,000; full landing page redesigns $10,000–$60,000. Tools like Hotjar, Microsoft Clarity, and basic A/B testing add $0–$300/month.

What Drives Conversion Rate
Conversion rate is shaped by page UX, trust signals, and friction in the funnel. The biggest CRO wins come from removing friction, not adding persuasion.

CRO vs Other Growth Levers
CRO compounds with every other channel — every dollar of paid or organic traffic becomes more valuable when conversion rate goes up.
CRO
- One-off investment, perpetual benefit
- Lifts ROI of every other channel simultaneously
- Highest leverage when traffic is already substantial
- Best paired with PPC and SEO that's already delivering volume
Buying More Traffic
- Linear cost — more traffic costs more money
- Diminishing returns at scale (CPM rises)
- Stops the moment budget stops
- Necessary but inefficient without strong CRO foundations
Raising Prices
- Highest-margin lift — every dollar drops to bottom line
- Conversion rate usually drops, offsetting some gain
- Works best when paired with stronger value framing (CRO)
- Test in segments before committing across the catalogue
