🧮13. Calculation Formulas and Methods

For complete transparency, here are the exact mathematical formulas used by each of our calculators. Understanding these formulas can help you verify results and better understand percentage calculations.

📊Percentage of a Number (What's X% of Y?)

Result = (Percent ÷ 100) × Base Number

Where: Percent is the percentage value (%), Base Number is the number you want to find the percentage of

Example: What is 15% of 200?
Result = (15 ÷ 100) × 200 = 0.15 × 200 = 30

Code Implementation: result = (percent * base) / 100

📈Percentage Calculation (What percent is X of Y?)

Percent = (Part ÷ Whole) × 100

Where: Part is the portion/number, Whole is the total/complete number

Example: What percent is 30 of 200?
Percent = (30 ÷ 200) × 100 = 0.15 × 100 = 15%

Code Implementation: result = (part / whole) * 100
Special Case: Division by zero is handled with appropriate error messages

📉Percentage Change Calculator

Percent Change = ((New Value - Old Value) ÷ Old Value) × 100

Where: New Value is the final amount, Old Value is the initial amount

Example: Change from 150 to 200
Percent Change = ((200 - 150) ÷ 150) × 100 = (50 ÷ 150) × 100 = 33.33% increase

Code Implementation: change = ((final - initial) / initial) * 100
Result Interpretation: Positive values = increase, Negative values = decrease

💰Tip Split Calculator

Equal Split Mode:

Tip Amount = (Total Bill × Tip%) ÷ 100
Total with Tip = Total Bill + Tip Amount
Per Person = Total with Tip ÷ Number of Guests

Where: Total Bill is the restaurant bill, Tip% is the tip percentage, Number of Guests is people count

Example: $100 bill, 18% tip, 4 guests
Tip Amount = ($100 × 18) ÷ 100 = $18
Total with Tip = $100 + $18 = $118
Per Person = $118 ÷ 4 = $29.50

Custom Tips Mode:

Total Tips = Sum of all individual tip amounts
Average Tip % = (Total Tips ÷ Total Bill) × 100

Example: $100 bill, tips: $15, $20, $10
Total Tips = $15 + $20 + $10 = $45
Average Tip % = ($45 ÷ $100) × 100 = 45%

Code Implementation:
Equal: tipAmount = (totalBill * tipPercent) / 100; perPerson = (totalBill + tipAmount) / numGuests
Custom: averageTipPercent = (totalTips / totalBill) * 100

💳Savings Calculator

Monthly Savings = (Monthly Income × Save%) ÷ 100
Annual Savings = Monthly Savings × 12
Total Savings = Annual Savings × Number of Years

Where: Monthly Income is monthly earnings, Save% is savings percentage, Number of Years is saving period

Example: $5,000/month income, 20% savings rate, 5 years
Monthly Savings = ($5,000 × 20) ÷ 100 = $1,000
Annual Savings = $1,000 × 12 = $12,000
Total Savings = $12,000 × 5 = $60,000

Code Implementation:
monthlySavings = (monthlyIncome * savingsPercent) / 100
totalSavings = monthlySavings * 12 * numYears
Field Synchronization: Changes to percentage automatically update amount field and vice versa

⚠️Calculation Accuracy Notes

JavaScript Precision: All calculations use JavaScript's built-in arithmetic, which may introduce small floating-point precision errors
Rounding: Results are rounded to 2 decimal places for currency and 1-2 decimal places for percentages using .toFixed()
Input Validation: Division by zero and negative numbers are handled with appropriate error messages
Range Limits: Some inputs have reasonable limits (e.g., tip percentage max 50%, years max 50)
Browser Compatibility: Calculations may vary slightly between browsers due to JavaScript implementation differences

Formula Verification

You can verify any calculation by using these formulas manually or in a spreadsheet application. We encourage users to double-check important calculations using alternative methods.
