Key takeaways

  • Sample only: $400,000.00 · 20% down · 6.5% · 30 years → about $2,022.62 P&I/month, ~$408,142.36 interest.
  • Shorter terms usually raise monthly P&I and lower total interest at the same rate.
  • Not a quote: Real loans may add PMI, fees, escrow, and different rate products.
  • Consumer mortgage education: CFPB — Mortgages

How it works

Nestfigure subtracts the down payment from home price, then amortizes the loan amount with a fixed monthly P&I payment. Optional tax, insurance, and HOA fields are simple add-ons you type. Details: how we calculate.

How does this mortgage calculator work?

Loan amount = home price − down payment. Monthly P&I uses standard fixed-rate amortization. Sample: $400,000.00 with 20% down at 6.5% for 30 years → about $2,022.62 P&I/month. Not a lender quote.

Does this include PMI, escrow, or closing costs?

No automatic PMI or closing costs. Optional tax, insurance, and HOA fields are only added if you type monthly amounts. Nestfigure does not look up tax rates or insurance premiums.

Can I prefill from a link?

Yes. Parameters: price, down, rate, years, tax, insurance, hoa.

Is this mortgage calculator free?

Yes—free, no signup. Educational math only; not underwriting or a rate lock.
