Marketing calculator
CAC, ROI, and conversion from pairs of numbers you enter.
What this tool does
The marketing calculator computes up to three ratios, and only from a complete pair. CAC is spend divided by customers. ROI is revenue minus cost, divided by cost. Conversion is conversions divided by visitors, shown as a percent. If you fill spend and not customers, CAC stays empty. The tool does not borrow an industry CAC, a typical conversion rate, or a competitor's revenue. At least one complete pair is required. Otherwise it asks you to enter one. Results are rounded to two decimal places. ROI is a ratio, not a percent, unless you multiply it yourself. A ROI of 1.25 means revenue exceeded cost by 1.25 times the cost.
How to use it
Enter the pair you actually have. Leave the others blank. Read only the figures that appear. If you want a percent, the conversion line is already in percent. Do not paste the ROI into a deck as a company result unless the revenue and the cost were that campaign's. The quiz on this hub asks the same question in words: the calculator refuses to invent a base.
Worked example
Spend ₹20,000 and 8 customers gives CAC ₹2,500. Revenue ₹45,000 and cost ₹20,000 gives ROI 1.25. Visitors 400 and conversions 20 gives conversion 5 percent. Drop the customer count and CAC disappears while the other two remain, which is the check that a blank pair is not filled in. ROI of 1.25 is not 125 percent unless you multiply the ratio by 100 yourself. The jobs link on this page searches HiringBuddy for published roles matching “sales”. An empty list means nothing published matched. It is not a comment on the wider market. A signed-in candidate can save the attempt on their profile. Saving is not an application, and it does not show the attempt to an employer. Employers see people who apply to their own jobs.
Questions
- Will it estimate CAC if I only know spend?
- No. CAC needs both spend and the customers that spend brought in.
- Is ROI shown as a percent?
- No. It is (revenue − cost) / cost. Multiply by 100 yourself if you want a percent.
- Does it include a benchmark?
- No. There is no default rate hiding in an empty box.
