First Home Budget Calculator: All Costs to Consider

Financial Expert

Quick Answer: What's the True Cost of Buying a Home?

Beyond the down payment, budget for: closing costs (2-5%), moving expenses ($1,000-5,000), immediate repairs ($5,000-10,000), furniture/appliances ($5,000-20,000), and ongoing costs like utilities, maintenance (1% of home value/year), and property taxes. Total upfront cost on a $300K home: $30,000-60,000+.

  • Upfront costs = down payment + closing costs + moving + immediate needs
  • Ongoing costs = mortgage + taxes + insurance + utilities + maintenance
  • Budget 1% of home value annually for maintenance
  • Emergency fund should cover 3-6 months of all housing costs
  • First year costs more—plan for extra expenses during transition
