Pricing
The calculators are free. Always.
You only pay when you want to keep the work — saved projects, payment applications, retainage tracked across periods, and documents with your name on them.
Plans are being updated. Every calculator remains free to use in the meantime.
Pricing FAQ
Before you decide
Are the calculators really free?
Yes, and they stay free. Every calculator works in full without an account — including the breakdown, the worked example and printing. Paid plans are for what happens after the calculation.
Do I need a card to try Pro?
No. You can create a free account, save calculations and see how the history works before deciding whether the rest is worth paying for.
Can I cancel whenever I want?
Yes. Cancel at any time and your plan stays active until the end of the period you have already paid for. We do not ask why and there is no cancellation process to sit through.
What happens to my data if I downgrade?
Nothing is deleted. Saved calculations and projects remain in your account; features above your plan become read-only until you upgrade again.
Do you offer annual billing?
Yes — annual works out at ten months for twelve. The saving is shown against each plan below.
