The page shows the formula, a numeric worked example, and the assumptions that affect this sales calculation.
Inputs and what they mean
- What are you measuring?
- — choice value.
- Starting count (leads, visits or clicks)
- — number value.
- Number that converted
- — number value.
How to use it
- Enter each value in the unit shown next to the box (use the unit converter first if your numbers are in other units).
- Check the breakdown to see every intermediate step.
- Read the limitations before relying on the result.
Formula
Methodology: one stage at a time — the starting count and the conversion must describe the same stage and period.
Works for sales funnels (lead → opportunity → deal) and marketing (visit → sign-up).
Define the conversion event yourself; nothing is assumed.
Conversion rate = conversions ÷ starting count × 100.
Inputs used: What are you measuring?, Starting count (leads, visits or clicks), Number that converted.
Worked example
Leads to customers
- 54 ÷ 1,200 = 4.5%.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Single stage.
- Mixed periods distort the rate.
- Results are educational estimates built only from the figures you enter. They are not personalised investment, tax, legal or accounting advice. Rates, growth and discount assumptions are always yours to choose.
- The result depends on the values you enter for this conversion rate calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Is there a good benchmark?
Benchmarks vary widely by market, deal size and sales motion. This page shows only your own figure and does not judge it.
