Conversion Rate Calculator

Turn visitors and conversions into a rate — and, if you add spend, into a cost per conversion.

The multiplier in your funnel

Conversion rate is the percentage of visitors who complete the action you care about. It is the highest-leverage number in most funnels, because it multiplies through everything upstream: doubling conversion rate halves your cost per customer across every campaign simultaneously, without touching a single bid.

The formula

Conversion rate = Conversions ÷ Visitors × 100
Cost per conversion = Total spend ÷ Conversions

Worked example

184 conversions from 8,000 visitors, ₹30,000 spend

Where the gains usually are

  1. Page speed. On Indian mobile networks this is frequently the single biggest lever, and the cheapest to fix.
  2. Form length. Every field removed lifts completion. Ask for what you need to make the first call, nothing more.
  3. Trust signals. GST number, address, a real phone number and genuine reviews measurably reduce hesitation for Indian buyers.
  4. Payment options. UPI as the default, and cash on delivery where the category expects it.
  5. Message match. The headline on the page should repeat the promise in the ad, in the same words.

Test one change at a time and let it run to a meaningful sample. Most declared "wins" in small accounts are noise from a few hundred sessions.

Frequently asked questions

What is a good conversion rate?

For e-commerce, 2–3% is a reasonable target. Service lead forms often reach 5–8%. A dedicated landing page for a single offer can exceed 10%.

Should I count micro-conversions?

Track them separately. Newsletter signups and WhatsApp clicks are useful diagnostics but should not be mixed into the same rate as purchases or qualified leads.

How much traffic do I need to test a change?

Enough to be confident the difference is not chance — usually a few hundred conversions per variant, not a few hundred visitors.
