How it works
Comparing daycare versus nanny cost is an exercise in three different pricing models rather than three hourly rates: a childcare center charges flat weekly tuition regardless of hours used, a nanny bills every covered hour and legally belongs on payroll, and a relative typically accepts a modest stipend instead of a market wage. This calculator prices all three models over your real coverage year. Daycare multiplies the weekly tuition by the weeks you need care; centers charge whether you attend five days or two, which is why part-time families often overpay. The nanny line applies the hourly rate to each covered hour, then adds a payroll load of employer-side taxes and contributions that usually runs 10 to 15 percent on top of wages and is the most commonly forgotten line in family budgets. Relative care converts a monthly stipend into an annual figure. With defaults of a $350 weekly center rate, a $20-per-hour nanny for 40 hours and a $400 monthly grandparent stipend, center care lands near $18,200 a year, the nanny near $46,600, and relative care near $4,800 — a spread wide enough that the cheapest option changes what a second income is worth at all. Price the options honestly first, then weigh flexibility, sick-day policies and one-on-one attention against the dollars.Formula
Daycare = weekly rate × weeks | Nanny = hourly × hours × weeks × (1 + payroll load%) | Relative = monthly stipend × 12
Tips
- Include the payroll load on nanny wages — taxes and contributions add 10–15% and are legally owed.
- Centers charge by enrollment, not attendance, so a part-time schedule rarely saves half.
- Ask centers about sibling discounts and nannies about sharing with a second family.
- Relative care still deserves a written agreement: hours, backup plan and what happens if health fails.
- Re-run the numbers yearly — infant rates drop as kids age into preschool pricing tiers.
