Marketing ROI Calculator. See the math before you spend the money.

Five focused calculators sharing one benchmark dataset: SEO, Paid Ads, Social, Web Design, and a Composite mode that bundles all four. Every number is industry-sourced. The math is shown. The on-screen number is always free.

SEO ROI Calculator

Project organic-search revenue and payback period from your monthly SEO investment. Uses a 9-month ramp curve sourced from agency benchmarks - SEO is not linear.

Your numbers

Projected 12-month return

Conversions / mo (at full ramp)--
New monthly revenue (at full ramp)--
12-month revenue (ramped)--
12-month SEO spend--
12-month ROI--
Approx. payback period--
SEO ramps over ~9 months, not day one. We weight months 1-9 with a benchmark ramp curve (10% -> 100%), then hold at full.
conv/mo = traffic x cvr
rev/mo = conv x AOV
12mo rev = sum(rev/mo x ramp_factor[month])
ROI = (12mo rev - 12mo spend) / 12mo spend

Ramp curve based on agency SEO benchmarks. Organic results compound; this projects the first 12 months only.

Paid Ads (PPC) ROI Calculator

Predict ROAS, cost-per-lead, and break-even AOV from your ad spend and landing-page conversion rate.

Your numbers

Projected monthly return

Clicks / mo--
Conversions / mo--
Cost per acquisition (CPA)--
Revenue / mo--
ROAS--
Profit after spend--
Break-even AOV--
clicks = spend / CPC
conv = clicks x cvr
CPA = spend / conv
rev = conv x AOV · ROAS = rev / spend
profit = (rev x margin) - spend
break-even AOV = CPA / margin

CPC and conversion benchmarks vary widely by industry. Plug in your real account data for accuracy.

Social Media ROI Calculator

Estimate monthly leads and cost-per-lead from organic social. Uses a 12-month average - organic social is a long-horizon brand play.

Your numbers

Projected monthly return

Engaged interactions / mo--
Clicks to site / mo--
Leads / mo--
Cost per lead--
Revenue / mo--
Monthly ROI--
posts/mo = posts/wk x 4.33
engaged = followers x eng_rate x posts/mo
clicks = engaged x CTR
leads = clicks x cvr
cost/lead = spend / leads
ROI = (leads x AOV - spend) / spend

Organic social is a 12-month brand play. Early months are reach-building; conversions lag.

Web Design ROI Calculator

Quantify the revenue lift from a conversion-focused redesign. Redesigns typically lift conversion 1.2x-2.5x.

Your numbers

Projected return

Conversions now / mo--
Conversions after / mo--
Added revenue / mo--
Added revenue / 12 mo--
12-month ROI--
Payback period--
conv_now = visitors x cvr
cvr_after = cvr x (1 + lift)
conv_after = visitors x cvr_after
added rev/mo = (conv_after - conv_now) x AOV
12mo ROI = (added rev/12mo - redesign) / redesign
payback = redesign / added rev/mo

A redesign is a one-time cost against a recurring lift. Most of the return shows up after month one.

Composite ROI - All 4 Channels Bundled

If you invest in SEO + Paid Ads + Social + a new Site, what is the projected 12-month return? Enter one set of business numbers and let us run all four models with shared benchmarks.

Your numbers

Projected 12-month return (all channels)

SEO 12-mo revenue--
Paid Ads 12-mo revenue--
Social 12-mo revenue--
Web redesign 12-mo lift--
Total 12-mo revenue--
Total 12-mo investment--
Blended 12-month ROI--
Runs the same four models above on one shared input set, then sums revenue and spend.
total rev = seo + ppc + social + web lift
total spend = (seo+ppc+social)x12 + redesign
blended ROI = (total rev - total spend) / total spend

Channels compound: shared brand lift means the bundled return is usually higher than the sum of the parts.

Frequently asked questions

Is the calculator really free?

Yes. The on-screen number is always free - no email required to see your projection. If you want a strategist to refine the numbers against your real data, that is an optional follow-up.

Where do the benchmarks come from?

Industry datasets from Unbounce, WordStream, Hootsuite, HubSpot, RivalIQ, Backlinko, and CXL Institute (2024-2025). We show the math behind every result so you can audit it - click "Show the math" inside any calculator.

Why does the SEO calculator use a ramp curve?

Because SEO is not linear. Rankings and organic traffic build over roughly 9 months, so we weight the first year with a benchmark ramp instead of assuming full results from day one. That gives a realistic 12-month payback estimate.

What is the Composite mode?

It runs all four models - SEO, Paid Ads, Social, and Web Design - on one shared set of business numbers, then sums the revenue and spend to project a blended 12-month ROI across your whole marketing mix.

Are these results guaranteed?

No. They are projections, not guarantees. Real results depend on execution, market conditions, and factors outside any spreadsheet. We share the math so the assumptions are transparent.

Can someone help me hit these numbers?

Yes. Call 1 (800) 858-1639 or email [email protected] and a MAD strategist will walk through your inputs and build a plan.
