What My Time Calculators is
My Time Calculators is a growing library of free tools designed to help you solve everyday calculations quickly and clearly. We focus on useful categories like finance, health, math, time, construction, AI & data, gemstones, travel, and more.
Many websites bury answers behind complex spreadsheets or paywalls. Our goal is the opposite: clean inputs, instant outputs, and plain-language explanations so your results make sense — not just the numbers.
Our mission
We want to reduce “calculation anxiety.” Whether you’re estimating a monthly payment, converting units, planning a project, or checking a formula, you should be able to do it in seconds on any device.
How our calculators are built
Each calculator is built with a consistent layout and user experience. Inputs are grouped logically, defaults are chosen to be reasonable, and results are displayed in a way that’s easy to scan. Where helpful, we add contextual notes so you know what the output means and what assumptions are involved.
What “estimate” means
Some calculators produce exact outputs (like unit conversions). Others are inherently estimates (like resale value, market-based pricing, investment forecasting, or construction material planning). In those cases, we aim to make assumptions visible, keep models sensible, and encourage users to verify critical decisions with professional or local guidance.
Accuracy, rounding, and transparency
We strive for accuracy, but results can vary based on rounding, regional rules, fees, taxes, and user inputs. If a calculator includes options (like compounding frequency, fees, or channel multipliers), those are included to help you model real-world scenarios more realistically.
Privacy-first mindset
We prefer calculators that work entirely in the browser when possible. Depending on how your site is configured, the website may still use basic server logs, analytics, and/or advertising — but we keep data collection minimal by design. For full details, see Privacy Policy and Cookie Policy.
Suggest a calculator or report an issue
We love practical requests: tell us what you’re trying to calculate and what inputs you expect. If something looks off, include your inputs and the result you expected so we can reproduce the issue quickly.
