Named organizational ownership
Free Calculators Online Editorial Team owns calculator definitions, source selection, worked examples, tests and corrections. We do not invent professional credentials or imply that a regulator endorses the site.
Arithmetic review
A review checks formula transcription, units, timing, boundary behavior, default examples and representative known values. Reusable formula families are tested once at the engine level and again through representative public pages.
Rule review
Current-year tax or program rules require a dated primary source and an explicit tax or benefit year. A calculator that depends on a user-entered official factor tells the user where the factor belongs instead of silently guessing it.
Editorial review
Every page must answer the question first, define inputs, explain interpretation, state exclusions, surface evidence and connect to a next useful tool. A published review date is not individualized professional advice.
Future credentialed review
If a credentialed external reviewer is engaged, the page will identify the person, credential, scope and review date. Until then, the site accurately attributes review to the editorial team only.
What review covers
Review confirms that the formula matches its stated description, that inputs are defined and units are consistent, that the worked example reproduces from the inputs shown, that limitations are stated, and that cited sources support the definitions they are attached to. It is a check of internal consistency and evidence, performed against the page as published.
What review does not cover
Review does not establish that a model is appropriate for any individual's circumstances, that an external rule has not changed since the review date, or that a figure entered by a reader is accurate. Those judgements belong to the reader, and no review date should be read as transferring them.
Triggers for re-review
A formula change, a rounding or convention change, a statutory figure update, a corrected source, a broken source link, or a correction affecting a shared formula. A change to explanatory wording alone does not move the review date, because the date is a signal about the calculation.
Ownership
Each calculator has an owner responsible for its formula, its inputs, its worked example, its limitations and its sources. Ownership means the obligation to re-check when any of those change, not merely authorship at publication.
What review covers, at a glance
| Question | Covered by review? | Why |
|---|---|---|
| Does the formula match its stated description? | Yes | Checked against the page as published. |
| Does the worked example reproduce from the inputs shown? | Yes | Recomputed from the prefilled inputs. |
| Do the cited sources support the definitions attached to them? | Yes | Evidence and internal consistency are what review checks. |
| Does the model suit your circumstances? | No | That judgement stays with the reader. |
| Has an external rule changed since the review date? | No | The review date is a signal about the calculation. |
| Was the number you typed in accurate? | No | Review cannot see your records. |
Frequently asked questions
Who is responsible for a calculator?
The Free Calculators Online Editorial Team owns every calculator's definitions, source selection, worked examples, tests and corrections. Each calculator has an owner who must re-check it whenever any of those change.
What does review confirm?
Review confirms that the formula matches its stated description, inputs and units are consistent, the worked example reproduces from the inputs shown, limitations are stated, and the cited sources support the definitions attached to them.
What does review not cover?
Whether a model suits any individual's circumstances, whether an external rule has stayed the same since the review date, or whether a number a reader typed in was accurate. The reader keeps those judgements.
What triggers a re-review?
A formula change, a rounding or convention change, a statutory figure update, a corrected source, a broken source link, or a correction affecting a shared formula.
Does a wording-only edit move the review date?
No. The review date is a signal about the calculation. A change to explanatory wording alone does not move it.
Are calculators reviewed by named professionals?
Not currently: review is attributed to the editorial team only. If a credentialed outside reviewer is ever engaged, the page will name the person, credential, scope and date.
What does an arithmetic review check?
Formula transcription, units, timing, boundary behavior, default examples and representative known values. Reusable formula families are tested once at the engine level and again through representative public pages.
How are current-year rules reviewed?
A current-year tax or program rule needs a dated primary source and an explicit tax or benefit year. A calculator that depends on a user-entered official factor tells you where the factor belongs instead of silently guessing it.
