Content investment payback
See how long an article or refresh would take to cover its cost.
Your scenario
- Whole months to pay back
- 6
- First-year contribution after upfront cost (USD)
- 600
— means the figure cannot be reached or calculated with these assumptions.
Formula
Payback months = upfront cost ÷ extra monthly contribution, rounded up. First-year balance = 12 × contribution − upfront cost.
Use additional revenue after ongoing costs, not total site revenue. Assumes a constant contribution; ignores tax and the time value of money.
Direct sponsorship price floor
Include the ad revenue you replace and the cost of delivering the placement.
Your scenario
- Cost-based price floor (USD)
- 750
- Implied sponsorship CPM (USD)
- 30
— means the figure cannot be reached or calculated with these assumptions.
Formula
Price floor = (replaced ad revenue + delivery cost) ÷ (1 − target margin). Implied CPM = price ÷ delivered pageviews × 1,000.
Assumes ordinary ads are fully replaced on these pageviews. This is your cost-based floor, not a market quote or proof of advertiser demand.
Newsletter acquisition break-even
Compare acquisition cost with a one-purchase contribution scenario.
Your scenario
- Acquisition cost per subscriber (USD)
- 3
- Contribution per subscriber (USD)
- 1
- Subscribers needed to cover spend
- 300
- Campaign contribution after acquisition (USD)
- -200
— means the figure cannot be reached or calculated with these assumptions.
Formula
Contribution per subscriber = purchase rate × contribution per sale. Break-even subscribers = spend ÷ contribution per subscriber, rounded up.
Choose one consistent campaign window. Assumes one purchase per converting subscriber. Excludes repeat purchases and future lifetime value.
Revenue concentration stress test
See the effect of losing part of your largest revenue source.
Your scenario
- Monthly revenue at risk (USD)
- 180
- Remaining monthly revenue (USD)
- 820
— means the figure cannot be reached or calculated with these assumptions.
Formula
Revenue at risk = monthly revenue × source share × assumed loss. Remaining revenue = monthly revenue − revenue at risk.
Enter a share of revenue, not a share of traffic. Holds every other source constant and does not predict future losses.
