Formula & Theory — Jumbo Loan Calculator
A jumbo loan exceeds the conforming loan limits set by the FHFA and is therefore not eligible for purchase by Fannie Mae or Freddie Mac. Lenders price jumbos with stricter credit, reserve, and down-payment requirements.
Loan = Price × (1 − down%)
Monthly P&I = L × r / (1 − (1 + r)^−n)
Total monthly = P&I + tax + insurance + HOA
| Symbol | Meaning |
