Upfront MIP
The upfront premium is calculated from the base loan amount. Many borrowers finance it, which raises the balance on which interest is charged. Enter the percentage as an assumption in the FHA loan calculator.
Annual MIP
Annual MIP is divided into monthly installments. HUD’s tables use loan term, loan-to-value, and balance thresholds; a generic calculator should never pretend one percentage fits every case.
What to verify
Check the FHA case-number date, property type, county loan limit, term, base loan, and lender’s Loan Estimate. The result here is a transparent planning estimate, not a premium quote.
