How do I verify weight loss percentage comparing before and after?

I was kg and I lost kg...
What percentage of body weight did I lose?

Type of calculation: Calculating percentage decrease.
How to use the calculator: First, find your new weight (80 kg - 8 kg = 72 kg). Then use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter the starting weight 80 [Original] and the new weight 72 [New]. It will calculate the drop.
The formula:
First, let's get the new weight:
New weight = Old weight - Weight lost
New weight = 80 kg - 8 kg = 72 kg
Now, find the percentage change from 80 kg to 72 kg.
Formula: ((New weight - Old weight) / Old weight) × 100%
Percentage change = ((72 - 80) / 80) × 100% = (-8 / 80) × 100% = -0.1 × 100% = -10% (minus means weight loss)
Another way (using "Part-to-Whole Percentage CALCULATOR"): You can simply check what percentage 8 kg (loss) is of 80 kg (start weight). Use the Part-to-Whole Percentage CALCULATOR ("What percentage of Y is Z?"). Enter 80 [Y] and 8 [Z]. You get 10%. Since it's a loss, that's a 10% decrease.

How do I calculate compound interest on my savings?

How much will I have in total?

Type of calculation: Calculating compound interest.
How to use the calculator: Since there isn't a dedicated "Compound Interest CALCULATOR" in our list, use a scientific or financial calculator. You can also use Excel or Google Sheets and the FV (Future Value) function.
The formula:
We want the final amount after 3 years with annual compounding.
General formula: A = P × (1 + r/n)^(n×t)

A – future value
P – principal amount
r – annual interest rate (as a decimal)
n – number of times interest is compounded per year
t – number of years

Since compounding is annual (n=1), the formula simplifies to: A = P × (1 + r)^t
Given:

P = $1000
r = 5% = 0.05
t = 3 years
n = 1 (annual compounding)

Calculation:
A = $1000 × (1 + 0.05/1)^(1×3)
A = $1000 × (1 + 0.05)^3
A = $1000 × (1.05)^3
A = $1000 × 1.157625 = $1157.63
Interest earned: Interest = A - P = $1157.63 - $1000 = $157.63

How much will I pay in total for two?

Type of calculation: Calculating a discounted value and adding it to the full price.
How to use the calculator:
Step 1: Find the price of the second product. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). The second item is 50% off, so you pay 100% - 50% = 50% of the regular price. Enter 50 [X] and 100 [Y]. It will calculate 50% of 100.
