Yes. Housing costs (PITI) are compared to a 28% front-end cap where applicable, and total monthly debts to a 36% back-end cap, which mirrors the classic conventional guidance many loan officers still cite. FHA and other programs can allow higher ratios with compensating factors, so treat 28/36 as a conservative planning band, not a universal approval limit.
PITI stands for Principal, Interest, Taxes, and Insurance. You can enter monthly property tax and homeowners insurance so they feed the affordability calculation. If you leave them blank, the tool may understate the housing load a lender will use, so add realistic local tax and insurance estimates for the ZIP you are targeting.
Yes. Select the programme toggle to see notes on typical FHA MIP versus conventional PMI assumptions. Actual MI quotes depend on credit score, loan term, and insurer; use the tool to compare directional payment differences, then request formal Loan Estimates from lenders.
No. A Loan Estimate is a regulated disclosure you receive after you apply. This page is a self-serve educational model only. For pre-approval, a loan officer will pull credit, verify employment, and issue a letter with a specific amount.
We summarise common affordability concepts consumers see on the CFPB’s educational materials (for example budgeting for total housing payment). We are not affiliated with the CFPB and do not provide legal compliance advice. Always read official disclosures from your lender.
Enter the higher home price and rate you were quoted. Jumbo underwriting is less standardised than agency conforming loans; caps and reserve requirements vary by investor. Use the output as a discussion baseline with a mortgage loan originator licensed in your state.
Banks apply automated underwriting engines (DU/LP), residual income tests, and overlays stricter than generic DTI rules. Self-employed borrowers often face additional average-income tests. The spread between this tool and a bank is expected.
If your monthly debt field includes HOA, the back-end ratio will rise accordingly. For finer control, add HOA to monthly debts rather than ignoring it, because many lenders count HOA in qualifying ratios.
The maths engine focuses on conventional/FHA-style repayment paths most users request. VA funding fees and USDA guarantee fees have special rules; ask a VA- or USDA-certified loan officer to model those programmes precisely.
No. US tax deductions for mortgage interest depend on IRS rules and your filing status. Speak to a CPA for tax strategy and to a CFP or loan officer for personalised mortgage guidance.
It produces estimation-level outputs from the inputs and assumptions you choose. Lenders apply proprietary credit policies, living-cost benchmarks, and verified documents that no public calculator can replicate. Treat every figure as a planning range, then validate with a regulated mortgage professional in your jurisdiction.
Mortgage numbers you type are processed locally in your browser to render charts and tables. This application is not designed to persist your form as a user profile. Standard hosting logs or third-party analytics may still exist—see the privacy policy for detail.
Yes. Affordability mode focuses on how much you may be able to borrow given income and debts, while repayment mode stresses the monthly instalment for a chosen loan amount. Switching modes lets you reconcile borrowing power with cashflow.
No. Mortgages intersect with tax (for example SDLT or mortgage interest deductions) and contract law. Nothing here replaces a qualified adviser, accountant, or solicitor. Regulatory references on the About page are for transparency only.
The editorial team reviews public guidance from central banks, regulators, and tax authorities on a best-effort schedule and documents the review cadence on the About page. Markets move daily—always confirm live pricing with your lender.
