Content investment payback
See how long an article or refresh would take to cover its cost.
Your result
- Whole months to pay back
- 6
- First-year contribution after upfront cost (USD)
- 600
A dash means there is no answer with these numbers, or the count is too large to show exactly.
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 result
- Cost-based price floor (USD)
- 750
- Implied sponsorship CPM (USD)
- 30
A dash means there is no answer with these numbers, or the count is too large to show exactly.
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 result
- Acquisition cost per subscriber (USD)
- 3
- Contribution per subscriber (USD)
- 1
- Subscribers needed to cover spend
- 300
- Campaign contribution after acquisition (USD)
- -200
A dash means there is no answer with these numbers, or the count is too large to show exactly.
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 result
- Monthly revenue at risk (USD)
- 180
- Remaining monthly revenue (USD)
- 820
A dash means there is no answer with these numbers, or the count is too large to show exactly.
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.
