Affiliate Income Calculator

Rough monthly payout from visits, CTR, purchase conversion %, and dollars earned per sale.

Overview

Use when you already have plausible traffic and funnel rates and want an order-of-magnitude commission check. Affiliate math changes quickly when click quality is poor, even if the commission looks attractive.

When to use this calculator

Rule of thumb

Small changes in conversion or traffic quality swing affiliate income harder than headline commission rates. Smooth with recent averages rather than single days.

Terms used in this calculator

Affiliate commission
Cash paid to publishers when attributed orders clear under affiliate rules.

Formula

Multiply monthly visitors × (CTR ÷ 100) × (conversion ÷ 100) × commission per sale. Rates are whole percentages in the inputs (for example 5 means 5%).

Example calculation

Using the default example values from the JSON seed for this tool:

Monthly visitors
10000
Click-through rate
5
Conversion rate
2
Commission per sale
40

Result: $400.00 (Estimated monthly affiliate income)

How to interpret this result

The result is an estimated monthly commission total for the funnel assumptions you chose.

It scales linearly with visitors until conversion or commission rates change—use recent blended averages.

Compare multiple scenarios when traffic quality swings by source.

Common mistakes

  • Using sitewide conversion for a single landing page offer.
  • Confusing gross commission with net after returns or clawbacks.
  • Ignoring mobile vs desktop conversion differences.

What to do next

Blog or newsletter calculators help when outbound clicks originate off-site.

How to improve this result

  • Send clicks from pages whose intent already matches the offer—random traffic rarely converts twice.
  • Negotiate creatives or landing pages when conversion is soft but CTR is healthy.
  • Rebuild segments after one partner changes payout rules so averages stay honest.

FAQ

What traffic number should I type?
Match whatever your analytics counts—usually monthly sessions or visitors on the monetized asset. Keep bot traffic out if possible.
Is this predicted income?
No. It is estimated cash if every rate stays flat; seasonality and stock-outs will move real payouts.
Do returns or clawbacks show up?
Not unless you folded them into a lower effective commission.
My niche has multiple offers—then what?
Run separate rows per offer or use a weighted average conversion and commission.
Why does CTR swing the result so hard?
Clicks sit in front of conversions—small CTR edits change how many people even see the offer.
