About ToolCR

ToolCR is a free website of online calculators. You enter a few numbers and get a quick estimate for things that are usually awkward to work out by hand: what a loan will cost over its life, how much tax you might owe, what a roof replacement could run, how an insurance refund is calculated, and many questions like these.

We built it because these questions tend to show up at inconvenient moments. You are comparing two mortgage offers, reading a settlement letter, planning a business purchase or looking at a contractor’s quote, and you just want a number you can check. Many calculator sites bury the tool under pop ups and long forms. Here the tool comes first.

What you will find on ToolCR

The calculators are grouped by topic, and you can browse every group from the home page. Current areas include loans and mortgages, real estate and rental income, tax, life insurance and other insurance, legal settlements and injury claims, retirement and pension, salary and payroll, business and ecommerce, trucking and shipping, construction and home projects, energy and solar, HVAC and engineering, plus a handful of everyday tools.

Some calculators follow United States rules. Others follow rules in the United Kingdom, Australia or elsewhere. If a calculator depends on a specific country’s rules, make sure it matches where you live before you rely on the answer.

Guides and blog articles

A number on its own does not always help, so ToolCR also publishes guides and blog articles on the same topics. They explain what a term means, which inputs change the result the most, the mistakes people commonly make, and what to ask before you sign or pay for anything. The idea is that a calculator and the article that explains it live close together. Under each blog post you will also see the latest articles from the same category.

How to use the site

Use the search bar at the top of any page. Start typing a keyword such as mortgage, solar, IFTA or settlement and suggestions appear straight away. Pick one and it opens. If you press enter instead, the home page shows every matching tool and article as a card. You can also scroll the home page and open a category to see everything inside it.

Who ToolCR is for

Homeowners and buyers, landlords and investors, small business owners, owner operators and drivers, students, contractors, and anyone who simply wants to double check a figure before making a decision.

A note on accuracy

Every result on ToolCR is an estimate for planning and general information. Real numbers depend on your lender, insurer, tax authority, local rules and the details of your own case, and rules change over time. Nothing on this site is financial, legal, tax or medical advice. For decisions that matter, talk to a licensed professional.
