About this calculator
Content marketing's ROI case is usually made on vibes because the payback period spans months and revenue attribution is fuzzy, but you can still build a defensible estimate. This calculator takes what a piece (or content program) costs to produce, its expected monthly organic sessions once it ramps, the share of sessions that convert to leads or sales, and value per conversion, then computes monthly value generated and the payback period in months. It also computes a 24-month value estimate assuming a decay curve, since organic content traffic typically ramps over 3-6 months, plateaus, then slowly declines as it ages and competitors publish newer content — modeled here with a simple monthly decay rate you set. Content with a payback period under 6 months and a decay rate under 3%/month is generally a strong repeatable bet; content requiring 18+ months to break even needs either a much lower production cost, a durable evergreen topic with minimal decay, or should be deprioritized in favor of formats with faster payback. This model assumes reasonably steady organic ranking; a single Google algorithm update can invalidate the traffic assumption entirely, so treat the payback estimate as a planning tool, not a guarantee.
Worked example
Using the values the calculator loads with:
Inputs
- Production cost (writing, design, promotion): 3000 $
- Expected steady-state monthly organic sessions: 2500
- Session-to-conversion rate: 1.5 %
- Value per conversion (lead value or order value × margin): 60 $
- Monthly traffic decay rate after peak: 2 %
Results
- Payback period: 1.3
- Monthly value at steady state: $2,250
- 24-month cumulative value: $43,225
- 24-month net value after cost: $40,225
- 24-month ROI: 1341%
What each field means
Inputs
- Production cost (writing, design, promotion) ($)
- The production cost (writing, design, promotion) used in the calculation, measured in $. Starts at 3000 $ so you have a working example on load.
- Expected steady-state monthly organic sessions
- The expected steady-state monthly organic sessions used in the calculation. Starts at 2500 so you have a working example on load.
- Session-to-conversion rate (%)
- The session-to-conversion rate used in the calculation, measured in %. Starts at 1.5 % so you have a working example on load. Accepted range: 0–50 %.
- Value per conversion (lead value or order value × margin) ($)
- The value per conversion (lead value or order value × margin) used in the calculation, measured in $. Starts at 60 $ so you have a working example on load.
- Monthly traffic decay rate after peak (%)
- The monthly traffic decay rate after peak used in the calculation, measured in %. Starts at 2 % so you have a working example on load. Accepted range: 0–20 %.

FAQ
What's a good payback period for a content piece?
Under 6 months is strong for most B2B and DTC content programs; 6-12 months is acceptable for competitive topics or larger cornerstone pieces; beyond 18 months you should question whether the traffic or conversion assumptions are realistic, or whether the topic is worth the investment at all.
How do I estimate steady-state monthly sessions before publishing?
Use a keyword research tool to find search volume for your target terms, apply an expected click-through rate based on realistic ranking position (position 1-3 often gets 20-35% CTR, position 4-10 much less), and haircut it for the fact that most content never reaches top-3 rankings. Conservative estimates beat optimistic ones here.
Why include a decay rate instead of assuming flat traffic forever?
Content ages: competitors publish newer or better resources, search intent shifts, and algorithm updates reshuffle rankings. A 2-5% monthly decay after the initial ramp is a reasonable planning assumption for most evergreen content; time-sensitive content (news, current events, annual trends) decays much faster, often 15-30%/month.
Does this account for content promotion or paid amplification?
Only if you include those costs in the production cost input and any resulting sessions in the traffic estimate. If you're paying to promote content via social ads, add that spend to production cost and make sure your session estimate reflects the paid-driven traffic too, not just organic.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
