How to Use This Calculator

Enter your current monthly household budget before the baby arrives.
Enter expected childcare cost, diapers & formula cost, and the monthly health insurance premium increase.
Enter your expected income change as a percentage — negative if income will drop (e.g., reduced work hours), positive if it will rise.
The calculator adds clothing/gear and pediatric-visit averages to your entries to estimate total monthly and first-year baby costs.
Review the adjusted monthly budget, monthly shortfall, required monthly income, and estimated lifestyle savings to see whether the new expenses are covered.
