How the three cards are defined
Price before tax is the amount on which the percent is charged. Price after tax is that amount plus the tax. The tax amount is the difference. When you type the price before tax, the page multiplies it by the percent you typed and divides by 100. A price of 1,000 and a percent of 18 produce a tax of 180 and a price after tax of 1,180. That sentence is multiplication. It is not a statement that clothing is taxed at 18, and it is not a statement that a dress costs 1,000. Eighteen is a number you might type because you have seen it on an invoice. If your invoice says a different percent, type that percent. The cards will move. The gown will not.
When the before field is blank and the after field is filled, the page runs the reverse. It treats the price after tax as 100 plus the percent, out of 100. A price after tax of 1,180 at 18 sits on a base of 118. Dividing 1,180 by 1.18 returns 1,000, and the tax is 180. The same 180 appears, because this row was built to undo the first one. A price after tax of 1,000 at 18 does not contain a tax of 180. The base is 1,000 divided by 1.18, which is 847.4576…, and the card rounds to 847.46. The tax card is 152.54, because 1,000 minus 847.46 is 152.54. Those two cards add back to the 1,000 you typed. The rounding is to the nearest hundredth, half up, so a later reader can rebuild the addition from the cards alone.
The hundredth is 0.01 of whatever currency you are using. The page does not round to the nearest rupee, dollar, or whole unit. A price of 999 at 12 percent gives a tax of 119.88 and a price after tax of 1,118.88. A price of 1,000 at 5 percent gives a tax of 50 and a price after tax of 1,050. A price of 1,000 at 18.5 percent gives a tax of 185 and a price after tax of 1,185. Five, 12, 18, and 18.5 are sample percents for the arithmetic. They are not a schedule of rates for fabric, garments, shipping, or video files. If a sample matches a rate you happen to use, that is a coincidence of the number, not a citation.
A blank percent leaves every card blank, even if a price is typed. Zero is a typed rate. A price of 1,000 and a rate of 0 produce a tax of 0 and a price after tax of 1,000. Use zero only when the invoice shows zero. Leaving the box empty means you do not have the rate yet. A percent above 100 also leaves the cards blank. A tax rate above the price itself is not a row this page will price. Type a percent from 0 through 100, including decimals if the invoice has them.
If you fill both price fields, the cards follow the price before tax and ignore the price after tax. The note says so. Clear the before field when you mean to extract tax from a total that already includes it. Filling both and hoping the page will reconcile them will not audit an invoice. It will add tax to the before price and leave your after price unused. Two prices that do not differ by the percent are a disagreement in the source documents. Look at the invoice. Do not average the two prices.
The same arithmetic is what people do with a sales-tax percent or a VAT percent: add the percent, or divide by one plus the percent. The legal name of the tax is the name on your invoice. This page is titled for GST because that is the name on Indian fashion invoices and on the FashionUGC terms. It does not convert one country’s tax into another’s, and it does not decide which name applies to your sale.
Worked rows, labeled as arithmetic
Use these rows only to check the tool. None of them is a dress, a tax assessment, or a FashionUGC charge. First row: price before tax 1,000, price after tax blank, tax percent 18. Tax amount 180. Before tax 1,000. After tax 1,180.
Second row: clear the before field, type 1,180 as the price after tax, and keep 18. Before tax returns to 1,000. Tax amount 180. After tax 1,180. If you get 999.99 or 1,000.01, reload and type the digits again without a comma. The page rejects commas. The two rows are inverses of each other on these exact inputs. They will not stay inverses after you change the price and keep the old tax card in a screenshot. Rerun the row.
Third row: price after tax 1,000, percent 18, before field blank. Before tax 847.46. Tax amount 152.54. After tax 1,000. Add 847.46 and 152.54 on paper. You should get 1,000. The tax is 18 parts out of 118, not 18 parts out of 100. Eighteen percent of 1,000 would be 180, and that is the wrong operation for a price that already includes the tax. The discount calculator is where “18 percent off” belongs. Eighteen percent off 1,000 is a sale price of 820. Eighteen percent off 1,180 is 212.40 off, leaving 967.60. Neither of those is 847.46. If a tag says 18 percent off and an invoice says tax at 18 percent, they are different sentences. Run the sentence you actually printed.
Fourth row: price before tax 999, percent 12. Tax 119.88. After tax 1,118.88. Fifth row: price before tax 1,000, percent 5. Tax 50. After tax 1,050. Sixth row: price before tax 1,000, percent 0. Tax 0. After tax 1,000. Seventh row: price before tax 1,000, percent 150. Every card stays blank. Eighth row: price before tax 800, percent 18, which is the kind of second step you do after a markdown, not a rate this page recommends. Tax 144. After tax 944. The 800 came from somewhere else. This page did not take 20 percent off 1,000. If that is where 800 came from, write “20 percent off 1,000, then tax at 18 on 800” beside the card. The discount calculator does the 800. This page does the 144. Doing both in your head and skipping the note is how 944 becomes an untraceable total.
The video does not contain the rate
A FashionUGC file is an MP4 made from clothing photographs. It has a length and a frame. It does not have a tax rate, a price before tax, or a price after tax. The generator does not print a percent on the cloth. The bronze gown example is a 10-second 9:16 file from a mannequin still. The floral dress example is a 10-second 9:16 file from an on-body still. Neither file was put through a tax invoice in a report this site can show you.
The stills keep the garment and the invoice as separate objects. You can see the gown and the dress. You cannot see 18 percent on them. If a deck prints a GST amount across one of these frames, the amount came from a rate someone typed, or it was invented. This page will not invent it. The examples are the place to watch the files. The product page is where a shopper sees a price. Whether that price includes tax is a fact about the page, not a fact about the MP4.
A generated frame can differ from the source photograph. The gown’s mannequin becomes a person. That is a reason to accept or reject the file before you attach a taxed price to it. It is not a tax event. A rejected file has no GST in this tool because you did not sell the video as a garment. The cloth still has to be nameable with the sound off, before tax and after tax.
One job is one garment and one colour. A floral dress and a black dress do not share a tax rate just because they share a banner. If one sale is taxed and another is not, they are two rows. Shipping can be a third row if the invoice taxes shipping at its own percent. This calculator has one rate field. Run it once per rate. Do not blend a garment at one percent with shipping at another and call the blend the dress. Add the tax amounts after each row is honest, and label the total as a sum of rows.
The empty rate box is the point
A GST calculator that opens with 5, 12, or 18 already typed is making a claim. This one opens blank. Rates are set outside this website, they are not the same for every textile, and they change. A page that remembered last year’s slab would keep giving last year’s answer. You type the percent that is printed on the document in front of you: a supplier invoice, a marketplace fee note, or your own tax settings. If two documents disagree, the cards cannot pick a winner. Run both percents and keep both notes.
The same restraint applies to FashionUGC’s own prices. A 10-second video is shown at ₹149, a 15-second video at ₹199, a 20-second video at ₹279, a 25-second video at ₹349, and a 30-second video at ₹500. Those are the prices shown before you pay. The terms say checkout may add GST or other tax on top of the price shown. “May” is the word on the page. This calculator does not know the percent checkout will use on a given day, and it will not pretend that ₹149 already includes tax or that a particular percent belongs on top of it. If you are checking a payment receipt, type the price from the receipt and the percent from the receipt. If the receipt has no percent, leave the rate blank. A blank card is the correct card.
Do not type 149 as the price of the gown. That number is a video length, not a garment. The margin between a dress and its cost belongs on the profit margin calculator, and only after you have put cost and price on the same side of tax. A cost that is before tax and a shelf price that is after tax will invent a margin. Strip the tax, or add it to both, and write which one you did. This page will not do that alignment for you, because it cannot see your cost.
A sales-tax percent from another country uses the same add and remove steps, and it still has to be the percent on that invoice. Do not paste an Indian sample into a foreign receipt because the arithmetic looks familiar. Name the tax in the note. The card will not name it. The title of this page is not a ruling that every price you type is GST.
One tax card, not a split
Invoices often break one tax into pieces. An intra-state sale may show two halves under two names. An inter-state sale may show the whole percent under one name. This page has a single tax amount, equal to the whole percent. It will not divide that amount by two. Halving is wrong when the invoice does not split, and it is wrong when the split is not equal. If you need the lines that appear on a particular invoice, copy them from that invoice. Use this page to check that those lines add up to the tax card, not to invent the lines.
A cess or a second levy is another percent, or a fixed amount. Run a second pass only if you know which base it uses. A percent of the price before tax is one pass. A percent of the price after the first tax is a different pass: take the after-tax card, clear the form, and use that number as the new price before tax with the second percent. Write “second pass” in the note. A fixed amount per unit is not a percent. Add it outside the calculator and say that you added it. Do not hide a fixed fee inside the rate, or the next person cannot rebuild the rate from the invoice.
Rounding on a long invoice is the other place totals drift. This page rounds each card to the nearest hundredth. An invoice that rounds each line to the nearest rupee, then sums, will not match a card that kept the paise. Neither method is “the” method until you say which document you are checking. If you are checking a line, use the line. If you are checking a total of a hundred lines, do not expect one card on one dress to reproduce the rupee rounding of the whole day. The card is one row.
Markdown, tax, and margin are three steps
Take a practice price of 1,000. A 20 percent markdown, done on the discount calculator, leaves 800. Tax at 18 on that 800 is 144, so the amount after tax is 944. Tax at 18 on the original 1,000 is 180, total 1,180, and a later 20 percent off that 1,180 would not be 944. Twenty percent of 1,180 is 236, leaving 944 only by coincidence of these particular numbers: 1,180 times 0.8 is 944, and 800 times 1.18 is also 944. Change the percent and the coincidence disappears. Twenty percent off, then 12 percent tax, on 1,000: the sale price is 800, the tax is 96, the total is 896. Tax at 12 first makes 1,120, and 20 percent off 1,120 is 896. Again they match. They match because a percent off and a percent of tax commute when both are simple percents of the current amount and no fixed fee sits between them. A “200 off” coupon does not commute with tax. Two hundred off 1,000 leaves 800, then 18 percent tax makes 944. Tax on 1,000 first makes 1,180, then 200 off leaves 980. Those are different offers. Know which one the code applies, then do the steps in that order. This page will not reorder them.
Margin comes after you know the price you actually collect and the cost you actually bear. If you collect 944 and the tax of 144 is not yours to keep, the price you type into the margin calculator is 800, not 944, unless your costing method keeps the tax in both revenue and a tax cost. If the unit cost of 400 is itself before tax, profit on the merchandise is 400 on a collected merchandise price of 800. That is a 50 percent margin and a break-even ROAS of 2, and it is still practice arithmetic from the discount page’s example, not a result. Type your own cost. If you leave the 144 inside revenue and forget it is tax, the margin looks richer than the cash you keep.
Orders in a store report may be tax-inclusive while an ad platform’s revenue is not, or the reverse. The ROI guide is where you match a week of orders to the price that was charged. Bring the tax treatment into that match. A ROAS built on tax-inclusive revenue against spend, compared with a break-even ratio built on tax-exclusive prices, will look like a win or a loss that is only a definition. Say “revenue includes tax” or “revenue is before tax” in the same sentence as the ratio.
What the cards cannot say
They cannot say the percent is correct. They apply the percent you typed. A wrong percent from memory produces a confident card and a wrong invoice. Read the document. They cannot say a dress is exempt, or that a marketplace will withhold tax, or that a buyer in another state changes the rate. Those are facts on the invoice and in the rules that apply to that sale. If you do not know them, the honest card is the blank one.
They cannot file a return, claim a credit, or choose an HSN. This page does not list codes, and it does not describe what you may deduct. A tax amount on a card is not an amount due to a government. It is the difference between two prices on one row. Your books may have adjustments this row does not contain. They cannot see a refund. If a dress comes back, the tax on that sale may reverse according to the invoice, not according to a new guess. Run the original row backward only if the credit note uses the same percent and the same base. Write the credit-note number beside the row.
They cannot make a video cheaper or more expensive. The file is the same MP4 at 1,000 before tax and at 1,180 after tax. Likes, clicks, and orders are counted on other pages, from numbers you export. A tax line is not an engagement rate and not a ROAS. Do not paste 180 into a campaign report as if the bronze gown had been taxed in a test.
Mistakes this page is here to catch
The first mistake is treating a worked row as FashionUGC’s tax. The 180 on 1,000 is division practice. It is not the tax on ₹149, and it is not the tax on a gown. A client report that says otherwise is a false report.
The second mistake is using the discount calculator to “remove GST.” Percent off and tax extraction are different divisions. The third is typing 18 because it feels familiar when the invoice says another number. The fourth is filling both price fields and believing the after price was checked. The cards added tax to the before price. The fifth is a percent above 100 left over from an inverted cell. The blank cards are intentional. The sixth is halving the tax card into two names the invoice does not use.
The seventh is one rate for two colours, or one rate for the garment and the shipping, when the invoice uses two rates. Split the rows, then add the tax amounts. The eighth is a comma or a currency sign. The field will not read them. Type 1180, not 1,180. The ninth is a mixed currency, a dollar price and a rupee habit, which still produces a neat hundredth and means nothing. The tenth is waiting for the tax card to forgive a file you have not watched. If the garment is wrong, the rate of the right garment is the one that matters, and the wrong file should not be the thing you sell.
Write the row so someone else can rerun it
Next to the cards, name the garment, the colour, and the invoice or product URL. Write the percent as it appears on that document, including the name of the tax. Write whether you added tax to a before price or removed tax from an after price. Write the date of the invoice. A percent from a different year is a different row, even when the dress is the same. If a markdown happened before the tax, write the sale price and the tool that produced it. If a credit note reversed the row, write the credit note. A screenshot of the three cards is not the source. Keep the invoice.
When someone asks why the tax is 152.54, you should be able to point at a price after tax of 1,000 and a percent of 18, and then say whether those were a real invoice or the practice row on this page. The practice row must never be the file you save into a client folder. If the invoice says 152.50 and the card says 152.54, do not silently change either one. The difference is rounding. Say whose rounding you are matching, and match it on purpose.
Two videos of the same colour at the same taxed price share one tax row. They do not share one click rate. Run this calculator once for the price. Run the ad and engagement tools once per post. The dress in the file is still the thing you have to be able to name. A tax of 180 does not identify a floral print, and a floral print does not prove that the price includes tax. Keep the picture and the invoice apart, and do not let either one impersonate the other.
