Increase the number 0.172 by 5% of its value
(1 + 5%) × 0.172 = ?
Brief introduction. Percentage Increase Change Calculation. Verification of the Result. Answer
Brief introduction. Definitions and formulas
Percent, p%
'Percent (%)' means 'out of one hundred':
5% = 5 'out of one hundred',
p% is read p 'percent',
5% = 5/100 = 5 ÷ 100 = 0.05
100% = 100/100 = 100 ÷ 100 = 1
How to increase the number 0.172
by 5% of its value?
The value of the percentage increase = 5% × 0.172
The new value = 0.172 + The value of the percentage increase
Detailed calculations and the calculation proof
1. Calculate the new value of the number...
... increased by percentage of its initial value
The new value =
0.172 + The value of the percentage increase =
0.172 + (5% × 0.172) =
0.172 + 5% × 0.172 =
(1 + 5%) × 0.172 =
(100% + 5%) × 0.172 =
105% × 0.172 =
105 ÷ 100 × 0.172 =
105 × 0.172 ÷ 100 =
18.06 ÷ 100 =
0.1806 ≈
0.18
2. Calculate the actual change (the absolute difference)...
... between the new value and the initial one
The actual change =
The new value - 0.172 =
0.1806 - 0.172 =
0.0086 ≈
0.01
Proof of calculation
We will prove below that the calculations are correct:
Calculate the value of the percentage increase and see if we get as a result the actual change (the absolute difference) between the new value and the initial one.
For positive numbers, the actual change = The value of the percentage increase
Calculate the value of the percentage increase:
The value of the percentage increase =
5% × 0.172 =
5 ÷ 100 × 0.172 =
5 × 0.172 ÷ 100 =
0.86 ÷ 100 =
0.0086 ≈
0.01
The value of the percentage increase = The actual change =>
The calculations are correct.
The answer:
:: written in two ways ::
Not rounded:
0.172 increased by 5% of the value = 0.1806
The actual change:
0.1806 - 0.172 = 0.0086
Rounded off to max. 2 decimal places:
0.172 increased by 5% of the value ≈ 0.18
The actual change:
0.18 - 0.172 ≈ 0.01
The symbols used: % percent, ÷ division, × multiplication, = the equal sign, / the fraction bar, ≈ approximately the same. Writing numbers: comma ',' - as a thousands separator, point '.' as a decimal mark.

How to calculate the new value of a number when increasing it by percentage of its initial value and how to calculate the absolute percentage change (difference)?
- New value = Initial value + Absolute percentage change (difference)
- Absolute percentage change (difference) = Percentage increase % × Initial value
- => New value = Initial value + Percentage increase % × Initial value = (1 + Percentage increase %) × Initial value
- In conclusion:
New value = (1 + Percentage increase %) × Initial value
Initial value = New value / (1 + Percentage increase %)
Absolute percentage change (difference) = Percentage increase % × Initial value = New value - Initial value
Four examples of calculations below.
- How to increase a number by percentage of its initial value (percentage increase).
- How to calculate the absolute percentage change (difference):
Example 1:
- If Percentage increase % = 20%, (1 + Percentage increase %) = 1 + 20% = 100/100 + 20/100 = 120/100 = 1.20 =>
- Number increased by value percentage = 1.20 × Initial value, and Initial value = Number increased by value percentage / 1.20; Absolute percentage change = New value - Initial value;
Example 2:
- If Percentage increase % = 5%, (1 + Percentage increase %) = 1 + 5% = 100/100 + 5/100 = 105/100 = 1.05 =>
- Number increased by value percentage = 1.05 × Initial value, and Initial value = Number increased by value percentage / 1.05; Absolute percentage change = New value - Initial value;
Example 3:
- If Percentage increase % = 124%, (1 + Percentage increase %) = 1 + 124% = 100/100 + 124/100 = 224/100 = 2.24 =>
- Number increased by value percentage = 2.24 × Initial value, and Initial value = Number increased by value percentage / 2.24; Absolute percentage change = New value - Initial value;
Example 4:
- If Percentage increase % = -8%, (1 + Percentage increase %) = 1 - 8% = 100/100 - 8/100 = 92/100 = 0.92 =>
- Number increased by value percentage = 0.92 × Initial value, and Initial value = Number increased by value percentage / 0.92; in this case we have in fact a decreasing of the value of the number; Absolute percentage change = New value - Initial value.
