Conversion Rate & Funnel Calculator
Conversion rate now, and the traffic you need to hit a target.
At a 2.00% conversion rate you need about 25,000 visitors to reach 500 conversions. A single point of CRO lift often beats buying that extra 13,000 of traffic.
About this calculator
Two questions come up constantly around any funnel: what's my conversion rate right now, and how much traffic do I need to hit a target number of conversions. This calculator answers both from the same three numbers, current traffic, current conversions, and a target, running the funnel math forward and then in reverse.
How to use it
- Enter your current visitors and conversions for the period, signups, leads, or purchases, whatever your goal event is.
- Enter a target number of conversions you want to reach.
- Read your current conversion rate, the total traffic required to hit that target at the current rate, and how much additional traffic that represents above what you have today.
Methodology
Conversion rate is conversions ÷ visitors, expressed as a percentage.
Required traffic to hit the target is target conversions ÷ conversion rate (as a decimal), the traffic volume needed to reach that target if the rate holds steady.
Additional traffic needed is required traffic minus current visitors, the incremental volume above what you're already getting.
This assumes the conversion rate stays constant as traffic scales, which isn't always true: some channels have diminishing returns at higher volume, others improve with better targeting. Treat the "traffic needed" figure as a planning baseline, not a guarantee that scaling traffic alone gets you there.
FAQ
Sometimes you can't improve conversion rate further without a redesign or product change that takes time, so more traffic is the faster lever. But the calculator's own math cuts both ways: a single point of CRO lift often requires far less additional traffic to hit the same target, worth comparing both options before committing budget to one.
No, it assumes your current conversion rate holds at higher volume. In practice, scaling traffic (especially paid) often pulls in lower-intent visitors who convert at a lower rate, so the traffic figure here is optimistic if quality degrades with volume.
Whichever goal event matters for the decision you're making. Use visitor-to-signup for top-of-funnel lead gen planning, or visitor-to-purchase for revenue-focused conversion work, just be consistent across the visitors and conversions figures you enter.
