Mortgage Calculator Oregon 2026: Payment, Tax & PMI
This mortgage calculator for Oregon estimates your full monthly payment — principal & interest, property tax, homeowners insurance and PMI — plus Washington County’s transfer tax if it applies. Enter your own rate; everything is calculated privately in your browser.
A mortgage calculator for Oregon estimates the full monthly cost of an Oregon home loan: principal and interest from standard amortization, plus property tax, homeowners insurance and private mortgage insurance (PMI) when you put down less than 20%. Oregon bans new real estate transfer taxes, so only Washington County’s $1 per $1,000 tax applies.
How the Mortgage Calculator Oregon Formula Works (Worked Example)
Principal and interest use the standard amortization formula M = P × r(1+r)n ÷ ((1+r)n − 1), where P is the loan amount, r the monthly rate (annual rate ÷ 12) and n the number of payments. Property tax is the home price × your local rate ÷ 12, insurance is your annual premium ÷ 12, and PMI is the loan amount × your PMI rate ÷ 12. Example: a $300,000 Oregon home, 10% down, 30-year fixed at a user-entered 6.5% (click Load Example above to reproduce it).
| Item | Inputs | Monthly |
|---|---|---|
| Principal & interest | $270,000 loan, 6.5%, 360 payments | $1,706.58 |
| Property tax | 0.81% of $300,000 ($2,430/yr) | $202.50 |
| Homeowners insurance | $1,450/yr (example — use your quote) | $120.83 |
| PMI | 0.6% of $270,000 ($1,620/yr) | $135.00 |
| Total monthly payment | $2,164.92 | |
| Transfer tax (one-time, Washington County only, $1 per $1,000) | $0 outside Washington County ($300 inside it) | $0.00 |
Over 30 years this loan pays about $344,370 in interest. Your rate is an input, not an assumption — check the current weekly national average in Freddie Mac’s Primary Mortgage Market Survey and compare lender Loan Estimates.
Oregon Property Tax Rate and Your Monthly Payment
Oregon homeowners paid an effective property tax rate of about 0.81% of home value in 2024 Census ACS data, according to the Tax Foundation’s Property Taxes by State and County, 2026. Under Measure 50, Oregon taxes the lower of real market value and a maximum assessed value that generally grows no more than 3% a year, so two similar homes can have very different bills. Ask for the current tax statement and enter annual tax ÷ price for the best estimate.
| Local rate | Annual tax on $300,000 | Added to monthly payment |
|---|---|---|
| 0.60% | $1,800 | $150.00 |
| 0.81% (statewide effective average) | $2,430 | $202.50 |
| 1.20% | $3,600 | $300.00 |
Oregon Closing Costs: Transfer Tax Only in Washington County
Oregon has no statewide real estate transfer tax, and ORS 306.815 bars local governments from imposing one unless it was in effect by March 31, 1997. Washington County’s tax, adopted before that date, is the only one: $1 per $1,000 of consideration (0.1%). Who pays it is set in the sale agreement. Choose “Yes” above if the home is in Washington County.
| Oregon item | Amount | Usually paid by |
|---|---|---|
| Real estate transfer tax | $0 statewide; Washington County $1 per $1,000 — $300 on $300,000 | Per sale agreement |
| Escrow deposits for tax and insurance | Set by your lender — see your Loan Estimate | Buyer |
| Lender, appraisal, title and recording charges | Vary by lender, title company and county — compare Loan Estimates | Negotiable |
Some costs are negotiable, and sellers sometimes cover part of a buyer’s closing costs as a concession.
How Oregon Mortgage Rates Affect Your Payment
Rates in Oregon follow national mortgage markets and vary by lender, credit score, down payment and loan type. On a $510,000 home with 20% down, an example 6.8% rate produces a monthly principal and interest payment of approximately $2,660. A 0.25% rate increase adds roughly $68 to that payment, so shopping multiple lenders can save thousands over the life of the loan.
Adjustable-rate mortgages (ARMs) often start lower but carry rate-reset risk. Most Oregon homebuyers choose 30-year fixed loans for payment predictability. FHA loans (3.5% down) and VA loans (0% down for veterans) are also popular in Oregon.
First-Time Buyer Programs in Oregon
Oregon Housing and Community Services offers the Oregon Bond Residential Loan and down payment assistance for eligible buyers. Check current eligibility and limits with the agency or a participating lender.
FHA loans are available nationwide and require only 3.5% down with a 580+ credit score — ideal for first-time buyers in Oregon who have limited savings. USDA loans offer 0% down for eligible rural properties in Oregon. VA loans are available to qualified veterans and active-duty service members with no down payment required and no PMI.
If your down payment is below 20%, Private Mortgage Insurance (PMI) on a $408,000 loan adds approximately $204/month at a 0.6% annual rate. The Urban Institute puts typical PMI at roughly 0.46%–1.5% of the loan per year depending on credit score. PMI can be removed once your loan-to-value ratio reaches 80%, so extra payments accelerate the timeline to dropping PMI.
