About Quik-Calc

Our Mission

Quik-Calc exists to give businesses and consumers free, transparent calculators — with the formulas, assumptions, and sources shown on every page so you can check the math yourself.

What We Offer

Free calculators across three categories:

  • Business & Technology: AI receptionist cost comparisons, internet speed analysis, WiFi coverage planning, business internet cost comparisons, and AI support savings calculators.
  • Finance: Mortgage, loan, compound interest, salary, rent-vs-buy, ROI, break-even, savings goal, and markup calculators with the formulas shown on the page.
  • Everyday: Tip, percentage, and age calculators for quick everyday math.

Who Operates Quik-Calc

Quik-Calc is owned and operated by Fuzzy Solutions, LLC (Elmira, NY) — the same operator listed on the contact page. The site does not use an editorial team or a panel of expert reviewers, and no licensed professionals review its content. Calculators use established formulas, published source data, and clearly identified modeling assumptions where appropriate, with the methodology and limitations documented openly. Anything on this site that depends on your specific situation (taxes, loans, investments) should be confirmed with the relevant agency, lender, or a qualified professional.

How the Calculators Are Built

Every calculator uses standard, published formulas — not invented ones. For example:

  • Tax withholding uses IRS-published 2026 federal brackets and Social Security Administration contribution bases.
  • New York state tax follows the official NY DTF Form IT-2105-I (2026) tax-rate schedule and tax-computation worksheets.
  • Internet speed guidance follows the FCC broadband benchmark; consumer finance guidance follows CFPB and Federal Reserve publications.
  • Loan, mortgage, and compound-interest math uses the standard amortization and compound-interest formulas.

Each calculator page includes a “Methodology and sources” section with the exact formula and links to the primary sources, so you can verify any result independently.

How They’re Tested

Calculator logic is covered by automated tests, known-answer examples, and edge-case checks, with cross-checks against published figures. Relevant tests and checks are run before calculator changes are deployed. This is automated verification of the math — it is not a substitute for professional advice on your personal situation.

How Time-Sensitive Data Is Updated

Year-sensitive constants (tax brackets, standard deductions, wage bases, rate schedules) are centralized in a single data module with a lastVerified date (for example, TAX_DATA_2026), so updates touch exactly one place. When agencies publish new figures — such as the next year’s IRS inflation adjustments — the constants are re-checked against the primary source and the verification date is refreshed. Pages that display dated constants show a “Data last verified” note (e.g., the salary calculator, currently verified 2026-09-09). Pages that are pure static math carry no date, because their formulas do not change.

Methodology Summary

  • Sources: primary, published sources only — IRS, SSA, NY DTF, FCC, CFPB, and Federal Reserve publications — linked from each calculator’s methodology section.
  • Testing: automated tests and edge-case checks run against the calculation engines before any change is published; failures block the release.
  • Update cadence: dated constants are re-verified when the issuing agency publishes new figures, and every page using dated constants displays its last-verified date. Static-math pages are reviewed for correctness but carry no date.

Corrections Policy

We aim to keep Quik-Calc accurate and current. If you notice a calculation error, a formula or source problem, outdated data, an incorrect source, a wording inconsistency, a broken link, or another factual problem, please report it via the contact page or support@quik-calc.com. Please include the calculator, your inputs, and the result you expected. We review reported issues and correct them when appropriate. For calculator-logic issues, we add or update regression tests when appropriate to help prevent the same problem from recurring. When a correction changes time-sensitive data or dated constants, we update the relevant verification information.
