 fin_percent R Documentation

## Compute the percent change needed to return to the original value after percent off (or on).

### Description

Determine the percent change needed to "undo" an initial percent change. Has a plot function as well. If an amount of \$100 has 20% added, what percent do we need to drop it by to return to the original value?

`fin_percent(20)` yields \$100 increased by 20% = \$120 (Percent to reverse = -17%)

### Usage

```fin_percent(
percent,
value = 100,
symbol = "\$",
digits = 2,
plot = TRUE,
logY = TRUE
)
```

### Arguments

 `percent` Change in percent (enter 10 for 10%, not 0.1) `value` Principal `symbol` value units (default = "\$") `digits` Rounding of results (default 2 places) `plot` Whether to plot the result (default TRUE) `logY` Whether to plot y axis as log (TRUE)

### Value

• `fin_interest()`

Other Miscellaneous Functions: `deg2rad()`, `fin_NI()`, `fin_interest()`, `fin_valuation()`, `loadings.MxModel()`, `rad2deg()`, `umxBrownie()`

### Examples

```# Percent needed to return to original value after 10% taken off
fin_percent(-10)
