How it works

The formula behind this calculator.

P = EMI × (1 − (1+r)⁻ⁿ) / r

This is the loan-amortization formula solved for the principal. It tells you how much house you can afford given your monthly budget.

Example: $1,800/month at 6% over 30 years → $300,000 max loan

Ref: PITI (Principal, Interest, Taxes, Insurance) is the true housing cost

Tips

💡 A 20% down payment avoids private mortgage insurance (PMI) in most markets.
💡 PITI = Principal + Interest + Taxes + Insurance — your true monthly housing cost.
💡 Locking in a lower rate at the start can save six figures over a 30-year loan.

FAQ
