Key Features
If you’re pitching SEO to a client, setting internal targets, or tracking whether your investment is paying off, this calculator gives you a credible, data-driven foundation to work from.

Calculate estimated revenue from organic search based on conversion rate and average order value.
Factor in monthly SEO costs to produce a true ROI figure and payback period.

Use Case | Description |
Client Pitching | Build a projected ROI model to support a new business proposal or upsell. |
Budget Justification | Demonstrate the expected return on SEO spend to finance or leadership teams. |
Goal Setting | Work backwards from a revenue target to define the traffic and conversion goals needed. |
Performance Benchmarking | Compare actual results against your original projections over time. |
Agency Reporting | Include projected vs. actual ROI in monthly client performance reports. |
Internal Planning | Model SEO scenarios to inform headcount, tooling, or content investment decisions. |
How to Use the SEO ROI Calculator
Step 1: Enter Your Baseline Metrics
Input your current monthly organic traffic, average conversion rate (as a percentage), and average revenue per conversion. These three figures form the baseline of your projection.
Step 2: Set Your Growth Rate
Enter your projected monthly organic traffic growth rate as a percentage. Be realistic — typical SEO growth rates range from 5% to 20% per month depending on the site’s starting point and investment level.
Step 3: Choose Your Timeframe
Select how many months you want to model — from 1 month up to 24. The projection table and chart will update accordingly.
Step 4: Add Your Monthly Investment
Enter your total monthly SEO cost, including agency fees, freelance costs, tools, and any internal resource time. This is used to calculate your net ROI and payback period.
Step 5: Review Your Projections
The results panel displays month-by-month traffic, conversions, revenue, cumulative spend, and ROI. A chart visualises the cumulative revenue curve against total investment.
Step 6: Download Your Data
Click Download as CSV to export the full projection table for use in client reports, board decks, or internal planning documents.
Additional Notes
All monetary figures are in GBP (£) by default.
The calculator uses compound growth — each month’s traffic is calculated from the previous month’s figure, not the baseline.
Conversion rate and order value are held constant across the projection. Adjust these manually between scenarios to model best, base, and worst case outcomes.
The payback period is the point at which cumulative SEO revenue exceeds cumulative SEO spend.
Tool FAQs
For additional questions or support, please contact [email protected]
How accurate are the projections?
The calculator produces estimates based on the assumptions you provide. Real-world results will vary depending on competition, content quality, technical SEO, and algorithm changes. Use it as a planning tool, not a guarantee.
What growth rate should I use?
This depends on your starting traffic, domain authority, and investment level. A new site with strong investment might target 10–20% monthly growth. An established site optimising incrementally might use 3–7%.
Can I model multiple scenarios?
Yes — adjust your inputs and the results update instantly. We recommend running at least three scenarios (conservative, base, and optimistic) for any meaningful business case.
Why is my ROI negative in early months?
This is normal. SEO takes time to compound. The payback period indicator shows when cumulative revenue overtakes cumulative spend — most campaigns reach positive ROI between months 4 and 12.
Can I change the currency?
The tool displays values in GBP. If you need a different currency, simply treat the figures as your local currency — the maths is identical.
Is my data saved?
No — all calculations happen in your browser. Nothing is stored or transmitted. Refresh the page to start a new projection.

Is SEO still worth investing in with AI search growing?
Yes.
The majority of AI search users still rely on Google and traditional search engines. AI tools complement search. They don’t replace it.
Brands that win in AI search are almost always strong in traditional SEO first.
What makes Growthack different from a traditional SEO agency?
We don’t treat SEO as a ranking exercise.
Growthack focuses on systems: technical foundations, content architecture, data integrity, and brand signals that drive real commercial outcomes.
Not vanity metrics.
What types of businesses does Growthack work with?
We work with established e-commerce, SaaS, and B2B brands that already have product–market fit and want predictable, sustainable growth from organic search.
Most of our clients are scaling, post-migration, post-rebrand, or preparing for international growth.
Is Growthack a good fit for early-stage startups?
Usually no.
We’re best suited to businesses that already have:
Existing demand
A validated product or service
Internal stakeholders ready to act on insight
If you’re pre-PMF (Product-Market Fit), paid or outbound is often a better first step.
For SaaS businesses, we’re best suited to working with brands that have already achieved significant funding e.g. Series A and are aiming to achieve further B, C etc rounds.
