Formula Used
Base underwriting fee = chosen fee basis from flat fee, percentage fee, higher value, or lower value.
Percentage underwriting fee = Loan Amount × Underwriting Rate.
Origination fee = Loan Amount × Origination Rate.
Discount points = Loan Amount × Discount Points.
Total underwriting fee = Base Underwriting Fee + Program Addon + Occupancy Addon + Credit Addon + Purpose Addon + Complexity Addon + LTV Addon + Rush Fee.
Total closing costs = Underwriting Fee + Origination Fee + Discount Points + Processing Fee + Admin Fee + Document Preparation Fee + Third-Party Fees + Other Fees.
Financed fees = Total Closing Costs × Financed Percentage.
Cash due at closing = Total Closing Costs − Financed Fees.
Monthly payment uses the standard amortization formula:
Where M is monthly payment, P is principal, r is monthly interest rate, and n is number of months.

Frequently Asked Questions
1) What is an underwriting fee?
An underwriting fee is a lender charge for reviewing risk, documents, credit, income, property details, and final approval conditions before funding a loan.
2) Is the underwriting fee the same as the origination fee?
No. Underwriting usually covers review and approval work. Origination often covers broader loan setup, pricing, and lender compensation. Some lenders separate them, while others bundle charges differently.
3) Can underwriting fees be financed?
Sometimes. Certain loans allow some closing costs to be added into the balance. That lowers upfront cash, but it increases the loan amount and usually raises total interest paid.
4) Why does loan-to-value affect fees?
Higher LTV usually means more lender risk. That can increase review depth, pricing adjustments, or reserve requirements, which may lead to higher underwriting-related charges.
5) Are third-party fees part of underwriting?
Not exactly. Appraisal, title, flood certification, and credit report costs are usually separate third-party or pass-through charges, but borrowers often evaluate them together with underwriting costs.
6) Do discount points reduce underwriting fees?
Usually no. Discount points buy down the interest rate. They are separate from underwriting charges, although both appear in closing costs and affect your total cash needed.
7) What is the best way to compare lender fee offers?
Compare total closing costs, fee categories, financed amounts, monthly payment impact, interest rate, and lender credits together. A lower underwriting fee alone does not always mean a cheaper loan.
8) Is this calculator a legal lending disclosure?
No. It is a planning tool for fee estimation and scenario analysis. Always verify final charges with your lender’s official loan estimate or closing disclosure.
