Built to be checked
No black boxes. Every result can be verified.
Every formula shown
Each page lays out the formula it uses with a worked example, so you can check the result yourself.
Private by design
Calculations happen in your browser — no sign-up, and nothing you type is saved by us. The Snow Day Calculator is the one exception: it sends your ZIP code to fetch a forecast.
Sources cited
Where a page relies on outside figures, such as IRS limits or industry benchmarks, it names the source.
Estimates, not advice
Results are for general information. For health, tax or investment decisions, confirm them with a qualified professional. See our Disclaimer.
What You'll Find Here
A short guide to what's on the site.
MyCalculatorLab is a small, growing collection of calculators for jobs people actually do: checking ad costs, sizing up a rental property, estimating self-employment tax, converting an A1C result, working out a room's area or a board's volume. You can read more about the site and who maintains it on the About page.
Finance and Business
The CPM Calculator works out cost per thousand impressions, total spend or impressions, and related metrics like CPC, CTR and CPA. The Cap Rate Calculator estimates a property's capitalization rate from its net operating income and value, and includes a builder for working out NOI from rent and expenses. The Self-Employment Tax Calculator estimates Social Security and Medicare tax on freelance or business income.
Health and Fitness
The A1C Calculator converts between HbA1c and estimated average glucose, and the Period Calculator estimates upcoming cycle and ovulation dates. The Bench Press Calculator estimates a one-rep max from a lighter set. These tools give estimates only and are not a substitute for advice from a doctor or other healthcare provider.
Math and Home Projects
The Age Calculator returns an exact age in years, months and days. The Square Footage Calculator covers rooms and houses, the Board Feet Calculator measures lumber, and the Snow Day Calculator estimates the chance of a school closure from the forecast.
FAQFrequently Asked Questions
Are these calculators free?

How accurate are the results?
