## Free tools for paid-traffic landers

Calculators for the numbers you check before you spend on a page: test size, builder cost and break-even conversion rate.

First calculators in progress

* [The full ranking](/best)
* [All reviews](/reviews)
* [Head-to-heads](/compare)

### Coming soon

The first calculators are being built now. Until they land, the ranking's table puts the top builders' starting prices, trials and split-testing side by side.

[Compare builder prices in the ranking](/best#compare)

Each calculator will show its formula beside the result and write the answer out in plain text, so you can paste it into a brief or a client report. These are the questions they will answer:

* **Split test size and duration.** How many visitors each variant needs before a lift is real, and how many days that takes at your daily traffic.
* **Builder cost by traffic.** What each builder bills at your monthly visitor count once page-view caps and overage are counted, beyond the entry plan's sticker price.
* **Break-even conversion rate.** The rate a lander has to hit for the payout to cover your cost per click.
* **Checkout fees.** What a platform's transaction cut adds up to at your monthly revenue.

### What a calculator answers that a review cannot

Most builder pricing pages quote a plan price and a visitor cap. On paid traffic the bill moves with your clicks, a split test that stops too early teaches you nothing, and a page that converts at 1.5% can lose money on one offer and print it on another. These are sums you can do on paper, but they get skipped when a campaign is ready to launch.

The cost calculators read the same vendor prices as our [reviews](/reviews), so when a vendor changes a plan, the review and the calculator change together.
