i Why 2%? How lenders differ

2% is a reasonable planning default for a streamlined IRRRL, not a fixed rule. IRRRL closing costs cover lender, title, and recording charges plus prepaids, and typically land somewhere around 2%–5% of the loan amount depending on the lender and your state. This figure is separate from the VA funding fee below.

What moves it:

Lender fees — origination/underwriting can be a flat fee or up to 1% of the loan; some lenders waive it. VA caps lender origination at 1%.
Rate vs. cost trade-off — a slightly higher rate can buy a lender credit that covers most costs (a "no-cost" IRRRL), lowering this number toward 0% but shrinking your monthly savings.
Title & state charges — title insurance, recording, and transfer taxes vary widely by state.
Prepaids & escrow — funding a new escrow account adds cash to close, but escrowed taxes/insurance are excluded from VA's recoupment math.

Set this to your Loan Estimate figure once you have real quotes. Lowering it lowers the minimum existing rate needed for viability.

Separate from closing costs. 0.5% of the loan, financed into the new balance.
i Who is exempt from the funding fee?

The VA funding fee is a one-time charge separate from closing costs. For an IRRRL it is 0.5% of the loan for most borrowers and is usually financed into the new balance. It's excluded from the 36-month recoupment test by statute — only the other closing costs have to be recouped.

You're exempt (0%) if you are:

• A veteran receiving VA compensation for a service-connected disability;
• A veteran who is entitled to that compensation but is receiving retirement or active-duty pay instead;
• A veteran rated eligible after a pre-discharge exam, or entitled based on a proposed/memorandum rating;
• A surviving spouse of a veteran who died in service or from a service-connected disability (or receiving DIC);
• A service member with a Purple Heart on active duty.

Exemption is confirmed on your Certificate of Eligibility (COE). Flip the toggle to Exempt to remove the fee from the math.

How VA IRRRL viability is decided (Net Tangible Benefit)
  • Rate-reduction test. The new rate must be at least 0.50% below your current rate for a fixed-to-fixed refinance, or at least 2.00% below for fixed-to-ARM (38 U.S.C. § 3709(b)).
  • 36-month recoupment test. All fees and closing costs — excluding taxes, amounts held in escrow, and the VA funding fee — must be recouped by your lower monthly principal & interest within 36 months (§ 3709(a)). Recoupment = recoupable costs ÷ monthly P&I savings.
  • Both must pass. The minimum viable existing rate is whichever of the two tests is stricter for your inputs.
  • Seasoning (separate requirement). Not modeled here: you must have made at least 6 consecutive payments and be at least 210 days past your first payment due date.
  • Term note. Resetting to a new 30-year lowers the monthly payment (making recoupment easier), but stretches payments out — which is why lifetime savings can shrink dramatically even when the monthly drop looks great.

Estimates only. This tool models VA's two core Net Tangible Benefit tests to illustrate viability; it is not a loan quote, an approval, or financial advice. Lender fees, title costs, and funding-fee exemptions vary — use your official Loan Estimate for real figures and confirm eligibility with a VA-approved lender.
