Your SaaS bill is lying to you

SaaS tools advertise one price and charge another. We document hidden fees, overage rules, and forced upgrades from public vendor pricing — so you can estimate the true cost before you sign up.

No signup required for the calculator. Estimates are based on public vendor pricing and the inputs you enter.

How StartupCost.ai Works

1

We document hidden fees from public pricing

We compile overage rules, forced-upgrade triggers, and extra charges from vendor pricing pages and documentation. Vendors change prices often, so always confirm on the vendor's site.

2

You enter your actual usage

Tasks per month, team size, storage needs, premium apps — the numbers that actually drive your bill. Not the default 'starter' usage the pricing page assumes.

3

We show what you'll really pay

Line-by-line breakdown: base price, per-seat costs, overage charges, hidden fees. Plus alternatives in the same category, ranked by estimated monthly cost.

4

Spot a wrong price? Tell us

Estimates are only as good as the pricing data behind them. If you find an outdated or incorrect price, report it and we will review it.

Common questions

How much does Zapier really cost?

Zapier advertises $29.99/mo for its entry paid plan. Costs can rise with task overages, multi-step Zaps that use more tasks, premium apps, and AI add-ons. Use the calculator with your own usage for an estimate.

What are SaaS hidden fees?

SaaS hidden fees include overage charges when you exceed plan limits, premium feature paywalls, per-seat cost multiplication, storage caps, API rate limits, and forced tier upgrades. How much extra you pay depends on the tool, plan, and your usage.

Is StartupCost.ai free?

Yes. The calculator, the cost ranges, the emailed report and every vendor page are free, with no usage limit and nothing to unlock. We document pricing for tools including Zapier, Airtable, Webflow, Make, and Notion. A $29/mo Pro subscription exists for readers who want to fund the pricing research, but it does not change what you can access.
