Bank Statement Loan Calculator for New Hampshire Self-Employed Borrowers

A bank statement loan lets self-employed New Hampshire borrowers qualify for a mortgage using 12 or 24 months of bank deposits instead of tax returns. This calculator estimates your qualifying monthly income, full PITI payment, and debt-to-income ratio in seconds, so you can see whether a bank statement program fits your numbers before you apply.

How this bank statement loan calculator works

Bank statement loans are non-QM (non-qualified mortgage) products built for self-employed borrowers whose tax returns understate their real cash flow. Instead of W-2s and 1040s, the lender averages deposits across 12 or 24 months and then applies an expense ratio to approximate net business income. This calculator uses the same logic underwriters do:

1. It multiplies your average monthly deposits by (1 minus your expense ratio) to get qualifying income.
2. It calculates principal and interest using the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the loan amount, r is the monthly rate, and n is the total number of months.
3. It adds estimated monthly property tax and homeowners insurance to produce the full PITI payment.
4. It divides total monthly debt (PITI plus other obligations) by qualifying income to give you a real-time DTI ratio.

How to use this calculator

1. Choose whether you are providing personal or business bank statements.
2. Enter your average monthly deposits across the statement period.
3. Adjust the expense ratio (50% is a common default for business statements; many personal statement programs use 0 to 15%).
4. Enter the home price, down payment, interest rate, and loan term.
5. Update New Hampshire property tax and insurance to match your town and home.
6. Add any other monthly debts (car loans, student loans, minimum card payments).
7. Review your qualifying income, PITI, and DTI ratio. A DTI at or below 43% is typically the comfort zone; many bank statement programs will stretch to 50% with strong reserves or credit.

What makes a bank statement loan work in New Hampshire

New Hampshire is one of the most self-employed-heavy states in New England, with a large share of independent contractors, real estate professionals, restaurant and hospitality owners, medical practice owners, and consultants serving the Boston metro from southern NH. Two pieces of state-level math matter most when you run this calculator:

• Property taxes are unusually high. New Hampshire consistently ranks among the top three states for effective property tax rate, with town-by-town variation that can swing your monthly payment by hundreds of dollars. Two homes priced identically in Manchester, Concord, Portsmouth, and Nashua can carry meaningfully different tax bills. Edit the property tax field to your specific town rate; do not rely on a national average.
• No state income tax helps your cash flow. NH does not tax earned income, which means more of your business deposits remain spendable. Bank statement underwriting cares about gross deposits, not taxed income, but the lack of a state income tax materially improves what self-employed New Hampshire borrowers can actually afford to carry as a monthly payment.

Bank statement loans are non-conforming, so they are not bound by the standard NH conforming loan limit. Lenders typically allow loan amounts well into the multi-million range when income and reserves support it, which is why this calculator can model larger purchases in Portsmouth, the Seacoast, the Lakes Region, and southern NH commuter towns without artificial caps.
