Break-Even ROAS Calculator
Estimate break-even ROAS using the price and costs you enter.
+

Illustrative estimates only. Results may vary and are not guaranteed. Uses only the price and costs entered; the contribution shown is before advertising. Omitted costs still apply. If costs equal or exceed price, no finite break-even ROAS is shown because no positive contribution remains to fund ads.

Illustrative estimates only. Results may vary and are not guaranteed. Assumes unique reach equals 60% of modeled impressions, capped by audience size when entered. This is not a delivery forecast. Duration is displayed for context and does not change the arithmetic.

12-Month Revenue Scenario
Model monthly revenue assuming your entered lead volume, close rate, ticket, and growth rate persist.
+

Illustrative estimates only. Results may vary and are not guaranteed. Assumes the entered monthly lead-growth rate compounds for 12 months while close rate and ticket stay fixed. Each month rounds modeled leads to whole leads, then rounds sales from that displayed lead count. Revenue is rounded sales multiplied by ticket value and excludes costs. The flat comparison uses the same rounding; month names label a hypothetical January–December period.

Profit Margin Calculator

A/B Test Significance Calculator
Compare conversion counts with an approximate two-proportion test; review test design before acting.
+

Illustrative estimates only. Results may vary and are not guaranteed. Outputs depend on the entered data and simplified model. They do not establish future conversion performance or a suitable spending level. The reported percentage is a coarse two-proportion z-test threshold, not the probability a variant will win. The approximation does not check sample adequacy, repeated testing, or randomization.

Email and SMS Comparison Tool
Compare your entered rates with fixed example values; these are not verified industry medians.
+

Illustrative estimates only. Results may vary and are not guaranteed. Email and SMS comparison values and color thresholds are fixed examples, not sourced industry medians. Audience, measurement methods, and tracking reliability differ.

Follow-Up Cadence Planner
Enter your sales cycle length and ticket size. Get a recommended follow-up timing sequence.
+

Illustrative estimates only. Results may vary and are not guaranteed. The schedule is an illustrative template. Timing and number of touches do not guarantee responses or sales; review consent, preferences, and channel requirements.

Ad Budget Planner
Work backwards from a revenue goal to an ad-spend scenario using your assumed close rate and cost per lead.
+

Illustrative estimates only. Results may vary and are not guaranteed. Assumes customer value, close rate, and cost per lead remain fixed. Lead and job counts are rounded up; service fees and other costs are excluded. A positive CPL is required. The alternative close-rate scenario adds up to five percentage points and is capped at 100%; lower modeled spend is not a promised saving.
