This is a multifunction template. At its simplest, it adds the currency mark "VNđ", as recommended by MOS:CURRENCY for many situations. The template can also link to the Vietnamese Dong article and can even calculate inflation. See warnings below in § Inflation calculation.

Usage

{{VND|number}}

Additional text like "million" or "trillion" must be placed outside the template, typically preceded by a non-breaking space (see example below).

Example:

{{VND}} → VNđ
{{VND|123.45}} → VNđ123.45
{{VND|123}}{{nbsp}}million → VNđ123 million

Link

The parameter |link=yes may be used to link VND to the article Vietnamese Dong. This is turned off by default, but may be appropriate for the first occurrence of the term in an article.

Example:

{{VND|123.45|link=yes}} → VNđ123.45

Suppress "VN"

By specifying |long=no, display of "VN" before the "đ" sign may be suppressed when it is clear from context that the Vietnamese Dong is meant, rather than one of the twenty or so other currencies going by the name of "dollar".

Examples:

{{VND|123.45|long=no}} → đ123.45
{{VND|123.45|long=no|link=yes}} → đ123.45

Inflation calculation

This template is only capable of inflating Consumer Price Index values: staples, workers' rent, small service bills (doctor's costs, train tickets). This template is incapable of inflating capital expenses, government expenses, or the personal wealth and expenditure of the rich; for such purposes refer to {{Inflation}}. Incorrect use of this template would constitute original research. If you are not sure and do not have economic training yourself, then please consult someone who does before using this template.

Do not assume that using this template will mean that a calculated value is "current", "as of 2024", "as of 2023" or even necessarily "recent". Do not use {{CURRENTYEAR}} to refer to calculated value, instead {{Inflation/year|VN}} may be used. See also MOS:REALTIME.

The template supports inflation calculation, by way of {{Inflation}}. If the second parameter is used, to specify a year, and this year is within a certain range of available inflation data (specifically, if 1995 ≤ year < 2022), the equivalent value represented in {{Inflation/year|VN} dollars will be calculated in parentheses. However, this function should only be used in appropriate situations.

{{VND|value|year}}
{{VND|value|year|round=round|about=yes}}

Examples:

{{VND|100|1994}} → VNđ100
{{VND|100|1995}} → VNđ100 (equivalent to đ441.44 in 2022)
{{VND|100|2010}} → VNđ100 (equivalent to đ177.31 in 2022)
{{VND|100|2010|link=yes}} → VNđ100 (equivalent to đ177.31 in 2022)
{{VND|100|2021}} → VNđ100 (equivalent to đ103.16 in 2022)
{{VND|100|2022}} → VNđ100
{{VND|100|2024}} → VNđ100
{{VND|100|2025}} → VNđ100

Additional parameter |about=yes will cause the template to calculate to the nearest dollar (instead of the nearest cent), and prefix the calculated value with "about". The rounding can be fine-tuned further by using |round=integer. These parameters may be combined.

Examples:

{{VND|10|1935}} → VNđ10
{{VND|10|1935|round=0}} → VNđ10
{{VND|10|1935|about=yes}} → VNđ10
{{VND|1000|1935|round=2}} → VNđ1,000
{{VND|1000|1935|round=-2}} → VNđ1,000
{{VND|1000|1935|round=-2|about=yes}} → VNđ1,000

Caution: The inflation-calculation code causes this template to approach the 40-deep expansion depth limit in the software that makes Wikipedia work. Pages that exceed this limit are placed in Category:Pages where expansion depth is exceeded. Using |about=yes can reduce the impact somewhat. If you call this template from within another template and use the inflation feature, consider adding a caution similar to this one to that template's documention page.

Show year

The parameter |showyear=yes may be used to show in YYYY between the amount and the inflation convertion. This is used for sentence structuring.

Example:

{{VND|100|1850}} → VNđ100
{{VND|100|1850|showyear=yes}} → VNđ100 in 1850
