VA IRRRL calculator: see your streamline refinance savings
If you already have a VA loan, an IRRRL lets you refinance to a lower rate with light paperwork. Enter your balance, your current rate, and the new rate you are quoted, and this tool estimates your monthly savings, the 0.5% funding fee, and whether you recoup the costs inside VA's 36-month rule.

What a VA IRRRL is
An IRRRL, the Interest Rate Reduction Refinance Loan, is the VA streamline refinance. If you already have a VA-backed loan, it lets you replace it with a new VA loan at a lower rate, or move from an adjustable rate to a fixed one. VA does not require a new appraisal or full income underwriting in most cases, which is why the IRRRL is fast and light compared with a purchase or cash-out refinance. You go through a lender, not VA directly, and the new loan pays off the old one.
The calculator above runs the comparison the way the VA disclosure does: your current payment versus the new one, the cost to get there, and how long it takes the monthly savings to pay that cost back. Everything runs in your browser, so nothing you enter is sent to me or stored.
The 0.5% funding fee, and who skips it
The VA funding fee on an IRRRL is 0.50% of the loan, a fraction of the 2.15% to 3.3% charged on a VA purchase loan. It is normally financed into the new loan rather than paid in cash. The fee is waived entirely for veterans who are exempt because of a service-connected disability and for eligible surviving spouses, so the calculator drops it to zero when you check the exempt box. This rate is set in the VA Lender's Handbook 26-7 funding-fee schedule.
The 36-month recoupment rule
VA protects veterans from refinances that cost more than they save. The rule: the costs of the IRRRL must be recouped through your monthly savings within 36 months. The math is simple, and the calculator does it for you:
- Add up the loan fees and closing costs.
- Divide by the reduction in your monthly principal-and-interest payment.
- The result is the number of months to break even. VA wants that at or under 36.
For example, $3,250 in costs against a $200 monthly reduction recoups in about 16 months, which passes comfortably. The same $3,250 against only a $90 reduction takes 36.1 months, which fails. VA's formal test excludes the funding fee, taxes, and insurance from the cost side, and your lender certifies the result before VA guarantees the loan. The break-even shown above counts all of your costs, so it is the honest, plain-English version of the same test.
The net tangible benefit: your rate has to actually drop
An IRRRL has to leave you better off, what VA calls a net tangible benefit. For a fixed-rate loan refinancing into another fixed rate, the new rate must be at least 0.50% (50 basis points) lower than your current rate. The one exception is moving from an adjustable-rate mortgage into a fixed rate: there the rate can hold steady or even rise, because the stability of a fixed payment is itself the benefit. The calculator flags whether your rate drop clears the 0.5% bar. These rules live in Chapter 6 of the VA Lender's Handbook 26-7.
Seasoning and the other IRRRL rules
A few eligibility rules decide whether you can do an IRRRL yet:
- You already hold a VA loan. The IRRRL refinances an existing VA-backed loan, not a conventional or FHA one.
- Occupancy. You certify that you live in, or used to live in, the home. Unlike a purchase, prior occupancy is enough.
- Seasoning. The loan you are refinancing must be seasoned: the first payment due date must be at least 210 days before the new note date, and you must have made six consecutive monthly payments.
- A second mortgage must be subordinated so the new VA loan stays in first position.

What this estimate is, and what it is not
This tool estimates your savings, the funding fee, the new loan amount, and the break-even period from the numbers you enter. It is not an approval, a pre-qualification, or a commitment to lend, and it does not pull your credit or verify your loan. The lender certifies the funding fee, the net tangible benefit, and the 36-month recoupment to VA before the loan is guaranteed.
Be cautious with refinance offers that promise skipped payments or rates that sound too good to be true, a warning VA itself makes. When you want real numbers on your file, I price your actual scenario and tell you honestly whether the refinance is worth it.
Common questions
What is the VA funding fee on an IRRRL?
The VA funding fee on an IRRRL is 0.50% of the loan, far lower than the 2.15% to 3.3% on a VA purchase loan. It is usually financed into the new loan rather than paid in cash, and it is waived for veterans exempt due to a service-connected disability and for eligible surviving spouses. The rate is set in the VA Lender's Handbook 26-7.
What is the VA 36-month recoupment rule?
VA requires that the costs of an IRRRL be recouped through your monthly savings within 36 months. The recoupment period is the total fees and closing costs divided by the reduction in your monthly principal-and-interest payment. For instance, $3,250 of costs against a $200 monthly reduction recoups in about 16 months and passes; against a $90 reduction it takes 36.1 months and fails. VA's formal test excludes the funding fee, taxes, and insurance, and your lender certifies it.
Does my interest rate have to be lower for a VA IRRRL?
For a fixed-to-fixed IRRRL, yes. The new rate must be at least 0.50% lower than your current rate to provide the required net tangible benefit. The exception is refinancing an adjustable-rate mortgage into a fixed rate, where the rate can stay the same or rise, because moving off an ARM is itself the benefit. These rules are in Chapter 6 of the VA Lender's Handbook 26-7.
Do I need an appraisal or income documents for an IRRRL?
Usually not. The IRRRL is a streamline refinance, so VA does not require a new appraisal or full credit underwriting in most cases. A lender may still order a credit report or appraisal for its own requirements and charge that cost, which can be financed into the loan. Because the process is light, IRRRLs tend to close faster than a purchase or cash-out refinance.
How soon can I do a VA IRRRL?
VA seasoning rules apply. The loan you are refinancing must be seasoned: the first payment due date must be at least 210 days before the new loan's note date, and you must have made six consecutive monthly payments on the existing VA loan. You also must already have a VA-backed loan and certify that you live in or previously lived in the home.
Wondering if an IRRRL is worth it?
Send me your current loan and I will run the real recoupment and net tangible benefit on your file, then tell you honestly whether the refinance pays off.
