Calorie Deficit Calculator
Enter your stats, activity level, and weekly loss goal to see your maintenance calories and a sensible daily target — based on the widely used Mifflin-St Jeor equation.

Freelance Hourly Rate Calculator
Enter your target yearly income, business expenses, and realistic billable hours to see the minimum hourly rate that keeps you whole.
Percentage Calculator

Rent Split Calculator
Enter the monthly rent, utilities, and both incomes to see what a fair split looks like — equal halves versus proportional to what each person earns.
