About SC Calculator
SC Calculator is a small, independent website. We build free online finance and general calculators that answer real questions.
We started because most calculator websites were either too complicated, paid subscription, or asked for a login before showing any result. We wanted something simpler and faster. Our goal is one thing: give you a useful informatics answer, right now, without getting in the way.

Trust rules for this site
We know that trust is important when people use tools for general information and financial calculation ideas. Here is how we try to:
- We write original content. Every calculator page uses our own words. We do not copy text from other sites. This page and every tool page on calculatorsc.com is written by us from scratch.
- We keep formulas simple and visible. Each tool uses a straightforward method. Where possible, we explain how the result was reached so you can follow the logic yourself.
- We do not ask for personal data. You can use every tool on the site without creating an account or sharing your name, email, or phone number.
- We do not store your inputs. Numbers you type into the calculators are not saved to our servers. The page does the math locally and shows the result. Nothing is sent or logged.
- We are honest about limitations. Our tools give useful estimates. They are not a substitute for a licensed accountant or financial advisor. We say that clearly on each page.
- We update content when things change. When formulas, rates, or guidelines change, we review the affected pages and update the numbers and copy. See the update section below for details.
Before using any result for an important financial decision, please read our disclaimer and verify with a licensed professional or official source.
How we write and check content
Every page on SC Calculator follows a simple editorial process. We write the description first, then verify the formula against a trusted source before the tool goes live. For pay and salary tools, we use widely accepted payroll and compensation methods. For business and pricing tools, we use standard accounting principles. For investing tools, we reference well-known financial formulas used around the world.
For example, our overtime pay calculator uses the widely accepted time-and-a-half rule (regular rate × 1.5 for hours beyond the standard work week). Our break-even calculator uses the standard formula (fixed costs ÷ contribution margin per unit). Each tool is built on a formula that can be understood, checked, and verified by anyone, anywhere.
We test every tool on mobile before it goes live. A calculator that is hard to read on a phone or takes too long to load is not useful, so speed and mobile layout are part of our standard review.
How we keep content up to date
Finance calculators can go out of date when pay rates change, when overtime rules are revised, or when new accounting standards are published. We review our most-used tools on a regular schedule and update them when anything changes.
When a tool is updated, we review the formula, the input labels, and the description to make sure they still match current standards. Major changes (like a revised pay rate or an updated accounting standard) are applied immediately. Smaller improvements (wording, layout) are grouped together and released at the same time.
What triggers an update?
- A financial standards body, accounting authority, or government agency anywhere in the world changes a rate, threshold, or rule that affects a pay or finance tool.
- A reader reports that a result does not match their own verified payslip, invoice, or financial records.
- We find a more accurate or more complete formula during a scheduled review.
- An accounting standard, depreciation method, or financial guideline is updated by an official body.
- A new tool is added to a category and nearby tools need updated cross-links or descriptions.
