About Muhammed
Muhammed Subhan is a Chartered Accountancy finalist with The Institute of Chartered Accountants of Pakistan (ICAP) and an Amal Fellow, currently completing his mandatory training. His work is in external audit, based in Lahore.
He has worked as an Audit and Tax Associate at Nauman Javed Hasnain Rashid Chartered Accountants, in the external audit department, finalising audits alongside his audit team. Before that he worked as an Accountant at TFMC, where he filed income tax and sales tax returns, prepared projected financials and handled corporate compliance tasks.
That background shapes how he reads a finance calculator: he looks at whether the figures follow the rules an accountant would apply, whether the financial data is handled accurately, and whether the result is explained clearly enough for the reader to use.
On Calculators Site he reviews the finance, tax, accounting and general-purpose calculators, checking that the formulas and explanations are accurate and clearly explained before they go live.

How Muhammed reviews our calculators
Every finance, tax, accounting and general-purpose calculator is checked before it goes live. A change to its method, source or supported population can call for a new review. A review covers:
- The formula. The calculation is compared with the published rule, standard or official guidance it is based on, including its rounding and order of steps.
- Rates and thresholds. Rates, bands, allowances and limits are checked against the official figures and the year or edition they apply to.
- Inputs and edge cases. Ordinary values, zero, negative amounts and values at a threshold are tried, and the input checks match the range the rules cover.
- The explanation. The page should say plainly what the result means, what it leaves out and when to speak to a qualified adviser, without giving personal financial, tax or professional advice.
Sources we rely on
A calculator is only as reliable as the method behind it. We build each one from published guidance, official sources and recognised standards, and avoid methods that only appear on other calculator sites or in marketing material.
Calculators built on a published formula, rule or guideline list their sources at the foot of the page, so you can check the method yourself.
Why you can trust our finance, tax, accounting and general-purpose calculators
- Checked by a Chartered Accountancy finalist with audit and tax experience. Every finance, tax, accounting and general-purpose calculator is reviewed by Muhammed before it goes live.
- Sources you can read. Calculators built on a rule or study link to it.
- Dated reviews. Each calculator shows when it was last reviewed, so you know how current it is.
- Your entries stay with you. Calculations run in your browser and are not sent to us as a personal history.
- Open to correction. If something looks wrong, you can report it and the calculator will be checked again.
These checks reduce risk; they don’t turn a calculator into professional advice. The full standards, including how automation is used and how corrections are handled, are in our editorial policy. If you think a calculator is wrong, tell us with the inputs you used, and the page will be checked again.
