PPC vs SEO Breakeven

PPC cost-per-click is flat. SEO's effective cost-per-click starts high and ramps down as organic traffic builds. See exactly which month SEO becomes cheaper than paid ads.

The comparison holds your PPC cost-per-click flat and divides your monthly SEO budget by the organic clicks an assumed 12-month maturity curve delivers — the breakeven month is the first month organic clicks work out cheaper than paid ones.

Enter what you spend on paid clicks, what you invest in SEO, and your typical cost per click — the comparison shows the month organic clicks become cheaper.

How the breakeven maths works

Three inputs drive everything: your monthly PPC budget, your monthly SEO investment, and the average cost per click in your niche. The chain runs:

  1. Target clicks — your PPC budget ÷ your CPC. That is the monthly click volume paid ads buy you today, and the yardstick SEO is measured against.
  2. SEO cost per click, month by month — each month, SEO is assumed to deliver a growing share of that target click volume (the ramp table below). Dividing your SEO budget by that month's organic clicks gives an effective cost per click that starts high and falls as rankings mature.
  3. Breakeven month — the first month where SEO's effective cost per click is no higher than your PPC cost per click. If that never happens inside 12 months, the tool says so rather than extrapolating beyond the model.

The organic ramp is an editorial assumption

The month-by-month curve below is a hand-authored modelling assumption — a plausible maturity path for a competently executed SEO programme, not measured data from Deltanoid client accounts or a published study. Real ramps vary widely with competition, site history and content velocity; treat the breakeven month as a planning estimate, not a forecast.

Reading it: at the default budgets (₹30,000 PPC / ₹20,000 SEO / ₹60 CPC), month 1 delivers 5% of the 500-click target — 25 organic clicks at an effective ₹800 each. By month 6 the ramp reaches 68% and the effective cost falls to about ₹59, dipping under the ₹60 paid click for the first time.

Assumptions this tool makes
  • The organic ramp (5% of target clicks in month 1 rising to 100% by month 12) is an editorial assumption, not measured data — real SEO timelines vary widely.
  • Your PPC cost per click stays flat for 12 months; in practice auction prices move with competition and seasonality.
  • Both budgets are steady-state: the same PPC and SEO spend every month, with no pauses or step-ups.
  • A click is a click — paid and organic clicks are treated as equally valuable, ignoring intent and conversion-rate differences between channels.
Limitations
  • The model stops at month 12 — it reports “beyond 12 months” rather than extrapolating a longer ramp.
  • It compares cost per click only, not cost per lead or revenue — pair it with the break-even ROAS calculator for the profitability view.
  • SEO spend compounds (content keeps ranking after you stop paying); PPC stops the moment budget stops. The cumulative chart shows spend, not that asset value.
  • It cannot tell you whether your specific niche will follow the assumed ramp — a competitive audit of your market is needed for that.
