如何從價格計算增值稅?
加稅時,稅額 = 未稅金額 × 稅率 ÷ 100,含稅總額 = 未稅金額 + 稅額。移除稅額時,未稅金額 = 含稅總額 ÷ (1 + 稅率 ÷ 100),稅額為兩者之差。稅率 10% 時,未稅 100000 對應稅額 10000、含稅 110000。反算應為 110000 ÷ 1.1 = 100000,而非從含稅金額直接減去 10%。

加稅時,稅額 = 未稅金額 × 稅率 ÷ 100,含稅總額 = 未稅金額 + 稅額。移除稅額時,未稅金額 = 含稅總額 ÷ (1 + 稅率 ÷ 100),稅額為兩者之差。稅率 10% 時,未稅 100000 對應稅額 10000、含稅 110000。反算應為 110000 ÷ 1.1 = 100000,而非從含稅金額直接減去 10%。
國家預設是標準或代表性稅率的參考值,部分管轄地區需手動輸入。實際稅率取決於管轄地區、商品或服務、免稅、優惠稅率及交易日期。選擇國家不會自動判定納稅義務,也不保證參考稅率始終最新;請確認當地稅務機關的規定。
輸入帳單金額,再選擇預設或自訂小費百分比;自訂值並非固定金額。帳單 100 加 20% 小費,總額為 120,3 人分攤每人 40。無法均分的餘數依最小貨幣單位分配,確保分攤合計一致。若提供總額無條件進位選項,會先把總額進位至整數貨幣單位,再分攤,差額計入小費。
計算在瀏覽器中完成。Google Analytics 和 Microsoft Clarity 預設以完整分析模式啟動。你可以在分析設定中主動選擇無 Cookie 模式;兩項服務仍會在不使用分析 Cookie 的情況下衡量使用情況。
利潤 = 售價 − 成本。利潤率 = 利潤 ÷ 售價 × 100;加價率 = 利潤 ÷ 成本 × 100。成本 80、售價 100 時,利潤為 20,利潤率為 20%,加價率為 25%。
每次折扣依序套用至剩餘價格:100 先折扣 20%,再折扣 10%,即由 100 到 80,再到 72。實際折扣為 28%,而非 30%。每一步依貨幣精度四捨五入,例如 USD 保留 2 位小數,KRW 與 JPY 按整數單位,因此小額結果可能與未四捨五入的公式不同。
Hanoon VAT & Tip Calculator
Hanoon is a Christian-founded brand identity shaped by the biblical vision of being kept as the apple of God’s eye and living before His gaze with grace, truth, reverence, and holiness.
Hanoon is a reverent digital platform rooted in the Christian faith, built on the biblical vision of being kept as the apple of God’s eye.
Our mission is to provide tools that help believers engage Scripture, worship, and everyday tasks with clarity and integrity.
Hanoon exists to serve the global church with digital tools that reflect the character of God: gracious, faithful, and attentive.
He found him in a desert land, and in the waste howling wilderness; he led him about, he instructed him, he kept him as the apple of his eye.
Keep me as the apple of the eye, hide me under the shadow of thy wings.
The primary meaning of Hanoon remains the biblical image of God’s eye, the apple of His eye, rooted in Deuteronomy 32:10 and Psalm 17:8.
As a welcome secondary sound resonance, the Korean name “하눈” can also sound like “하는” and opens toward active expressions such as 찬송하는, 통독하는, 기도하는, and 찬양하는. This secondary resonance enriches but never replaces the primary biblical meaning.
Official slogan: Hanoon — His gaze, our grace.
Poetic HANOON mnemonic, not the official slogan or a formal doctrinal formula: His Apple, Never Out Of Notice.
Hanoon holds together two truths: we are kept by God as precious in His sight, and we are called to live before God in truth, holiness, and reverence.
This dual meaning is essential. Hanoon is not only about comfort or being loved by God. It is also about accountability, integrity, purity, and a life lived consciously before Him.
Hanoon’s theological boundary is broadly Reformed, Evangelical, Presbyterian, historically confessional Protestant. Truth before trend. Reverence before spectacle. Grace without compromise. Holiness without harshness.
Holy Scripture is inspired, trustworthy, sufficient, and the final authority for faith and life. Hanoon affirms Sola Scriptura, Sola Gratia, Sola Fide, Solus Christus, and Soli Deo Gloria.
Jesus Christ is true God and true man, the only Savior and Mediator. Fallen people cannot save themselves; salvation comes through Christ’s life, death, and resurrection and is received by grace through faith, leading to repentance, humility, obedience, sanctification, holiness, and perseverance.
The Holy Spirit convicts, regenerates, sanctifies, illumines, comforts, empowers, and builds the church. Every spiritual claim and experience remains under the authority of Scripture.
Hanoon aims to be reverent, clear, intelligent, calm, grounded, and honest. The design system, navigation, content surfaces, and product tone should feel disciplined rather than showy.

Hanoon uses only the data needed to operate each service, keep sessions stable, protect the platform, and perform privacy-safe analytics or usage measurement. Eligible user routes begin with analytics storage enabled by default unless you have opted out; denied-storage traffic continues with provider-defined cookieless measurement.
Hanoon VAT & Tip Calculator may process technical data that is required to deliver the site, keep sessions stable, protect the service, and measure product quality. Eligible user routes use analytics storage by default for continuity; after an explicit opt-out they continue with provider-defined cookieless measurements.
Depending on the service, this can include cookies and localStorage values, privacy-safe analytics or usage measurement, authentication or session data, media delivery requests, or messages that you intentionally submit through support flows.
Many Hanoon tools are designed to work primarily in the browser. When a tool can complete its job locally, your working content may remain on your device.
If a service needs third-party infrastructure such as authentication, storage, privacy-safe analytics or usage measurement, or form handling, only the data needed to operate that feature should be used.
On eligible user routes, approved analytics providers load immediately after private URL state is excluded. Analytics storage and cross-page or session continuity are enabled by default without a prompt. Turning analytics storage off returns measurement to denied cookieless or no-consent mode and removes supported provider cookies without disabling aggregate measurement.
File contents, file names, passwords, free-form tool input, and generated output are excluded from analytics. Hanoon may store your consent choice and other non-analytics session or preference values in cookies and localStorage, which you can review or clear through browser settings.
You can control theme and locale preferences through browser storage settings. You can also avoid submitting optional personal information through support or contact flows.
