Free Shopify tools

Quick calculators for product launch decisions.

These tools are designed to catch obvious issues before a seller pays for samples, apps, inventory, or ad tests.

Ad math

Break-even ROAS calculator

Find the return on ad spend needed before ads stop losing money.

Contribution before ads $0.00
Break-even ROAS 0.0x
Ad risk Checking...

Lower break-even ROAS leaves more room to scale.

Cash planning

Launch budget estimator

Estimate how much a simple product test could cost before meaningful data appears.

Estimated test budget $0.00
Ad spend included $0.00
Budget note Checking...

This is a planning estimate, not a promise of results.

Product filter

Product viability score

Score a product idea before doing deeper research.

Product score 0/100
Next step Checking...

A score is a filter. A paid report still needs competitor and supplier checks.

Average order value

Bundle price helper

Check whether a bundle can lift order value without crushing margin.

Suggested bundle price $0.00
Bundle gross profit $0.00
Gross margin 0%
Bundle signal Checking...

Bundles help only if the margin survives the discount.

Risk buffer

Refund impact calculator

Estimate how refunds, replacement costs, and support issues can change real profit.

Profit before refunds $0.00
Estimated refund drag $0.00
Profit after refunds $0.00
Refund signal Checking...

High refund drag usually means supplier quality or expectations need work.
