If Mary earns ₦50 000.00 per month and spends ₦35 000.00 altogether, then her savings would be ₦15 000.00. To calculate the percentage of her savings, we can use the following formula:

To find Mary’s savings percentage, divide her savings by her earnings, then multiply by 100.
Savings = Earnings – Spending
Savings = 50,000.00 – 35,000.00
Savings = 15,000.00
Percentage = (Savings / Earnings) * 100
Percentage = (15,000.00 / 50,000.00) * 100
Percentage = 30%
So, Mary saves 30% of her earnings.
If Mary earns ₦50,000.00 monthly and spends ₦35,000.00, her savings are ₦15,000.00. To find her savings percentage, divide ₦15,000.00 by ₦50,000.00, then multiply by 100. Mary saves 30%.
Example 1:

Solution:
Savings = Earnings – Spending
Savings = ₦40,000.00 – ₦28,000.00
Savings = ₦12,000.00
Percentage = (Savings / Earnings) * 100
Percentage = (₦12,000.00 / ₦40,000.00) * 100
Percentage = 30%
Example 2:
John’s monthly earnings are ₦60,000.00, and he spends ₦45,000.00. Determine his savings percentage.

Savings = ₦15,000.00
Percentage = (Savings / Earnings) * 100
Percentage = (₦15,000.00 / ₦60,000.00) * 100
Percentage = 25%
Example 3:
If Amina earns ₦25,000.00 per month and spends ₦20,000.00, find her savings and the percentage saved.

Percentage = (₦5,000.00 / ₦25,000.00) * 100
Percentage = 20%
Example 4:
