A mortgage calculator can help you see how various mortgage term lengths and interest rates will affect your monthly payments. Use this mortgage calculator to explore different outcomes.

You can bookmark the Yahoo Financemortgage payment calculatorand keep it handy for future use, as you shop for homes and lenders. It also considers factors like property taxes and homeowners insurance when calculating your estimated monthly mortgage payment. This gives you a better idea of your total monthly payment than if you just looked at the mortgage principal and interest.

Generally, 15-year mortgage rates are lower than those for 30-year mortgages. When comparing15- versus 30-year mortgage rates, know that the shorter term will save you money on interest in the long run. However, your monthly payments will be higher because you’re paying off the same loan amount in half the time.

For example, with a$400,000 mortgagewith a 30-year term and a 6.37% rate, you'll make a monthly payment of about$2,494toward your mortgage principal and interest. As interest accumulates over decades, you’ll end up paying$497,902in interest.

If you get a $400,000 15-year mortgage with a 5.65% rate, you’ll pay about$3,337monthly toward your principal and interest. However, you’ll only pay$200,597in interest over the years.

If that 15-year mortgage monthly payment is too high, remember you can always make extra mortgage payments on your 30-year loan topay off your mortgage fasterand ultimately pay less interest.

Discover how to get the lowest mortgage rates.

With afixed-rate mortgage, your rate is locked in from day one. However, you will get a new rate if you refinance your mortgage.

Anadjustable-rate mortgagekeeps your rate the same for a specified period. Then, the rate will increase or decrease depending on several factors, such as the economy, and the maximum amount your rate can change according to your contract. For example, with a 7/1 ARM, your rate would be locked in for the first seven years, then adjust annually for the remainder of your term.

Adjustable rates sometimes start lower than fixed rates, but once the initial rate-lock period ends, you risk your interest rate going up. ARM rates have also been starting higher than fixed rates recently, so you may not always get a rate break.

Determine how to choose between an adjustable-rate vs. fixed-rate mortgage.

According to Zillow data, today's 30-year fixed rate is 6.37% for home purchases and 6.36% for refinances. These are the national averages, so keep in mind the average in your state or city could be different. Your rate will also vary depending on your personal finances.

According to the latest forecasts, the MBA expected the 30-year mortgage rate to be near 6.10% through the end of 2026. Fannie Mae also predicted a 30-year rate near 6%, though falling to 5.7% by the end of the year.

Mortgage rates are likely to remain little changed in 2027. The MBA forecasts 30-year fixed rates of 6.20% to 6.30% for most of 2027. Fannie Mae predicts average rates near 5.7% for the full year of 2027.

Opening Takes

Claude by Anthropic

▬ Neutral

"Rate direction matters far less than the *reason* rates move—sticky inflation driving 6%+ rates is bearish for housing and equities; Fed pivot driving rates to 5.7% is bullish for both."

The article presents a straightforward rate-rise narrative—6.37% on 30-year fixed, up 25bps in a week—but buries the real story: forecaster disagreement. MBA expects 6.10–6.30% through 2026–27; Fannie Mae predicts 6.0% falling to 5.7% by year-end. That's a 60bps spread on year-end 2026. The Iran geopolitical reprieve Monday briefly lowered yields, yet rates still rose week-over-week, suggesting the move is driven by something other than headlines—likely Fed policy expectations or inflation data the article doesn't specify. Housing affordability at 6.37% is materially worse than at 5.7%, but the article doesn't quantify demand destruction or lock-in effects (existing homeowners with sub-4% rates staying put).

Devil's Advocate

If Fannie Mae's 5.7% forecast proves right, today's panic about 6.37% looks premature; the real risk is that rates stay elevated *because* inflation remains sticky, which would be worse for equities and credit than a temporary rate spike.

"The inversion of ARM rates over fixed rates indicates a broken mortgage market that will further paralyze housing turnover."

The 25-basis-point jump in 30-year fixed rates to 6.37% signals a breakdown in the 'soft landing' narrative for housing. While the article cites geopolitical de-escalation in the Strait of Hormuz as a reason for falling bond yields on Monday, mortgage rates are lagging or decoupled due to volatility risk premiums. Most concerning is the inverted spread where 5/1 ARMs (6.50%) are priced higher than 30-year fixed loans (6.37%). This 'inverted mortgage curve' suggests lenders are pricing in significant long-term uncertainty, effectively killing the incentive for buyers to use adjustable-rate products to hedge against current high costs. This will likely freeze inventory as the 'lock-in effect' intensifies.

Devil's Advocate

If the geopolitical cooling mentioned leads to a sustained drop in the 10-year Treasury yield, mortgage spreads could compress rapidly, making this 6.37% peak a short-lived anomaly rather than a trend.

"6.37% 30-year rates will suppress spring housing demand, forcing homebuilders into deeper discounts and margin erosion evident in upcoming Q2 reports."

Mortgage rates at 6.37% for 30-year fixed (up 25bps WoW per Zillow) despite Monday's Treasury yield dip on Trump delaying Iran Strait deadline, signal persistent upward pressure tied to weekly yield gains—likely reflecting inflation fears or fiscal policy under Trump. Affordability erodes further (e.g., $400k loan monthly P&I jumps ~$60 vs. 6.12% last week), crimping purchase demand and refis; MBA data shows >20bps moves crush apps 10-15%. Homebuilders (DHI, LEN, TOL) face margin squeeze via incentives, originators (RKT) volume drought. Forecasts (MBA 6.1% YE26, Fannie 5.7%) hinge on Fed cuts, but omitted: Trump's tariffs could spike CPI, keeping yields elevated. Near-term bearish housing sector.

MBA/Fannie Mae consensus forecasts sub-6% rates by YE26 assume Fed easing amid cooling inflation, potentially unlocking pent-up demand if home prices continue declining as sidebar notes.

The Debate

Claude ▬ Neutral

"The 60bps forecaster divergence on 2026 rates is a bigger signal than this week's 25bps move—it reveals where the real disagreement lies, not geopolitics or near-term affordability."

Grok flags tariff-driven CPI persistence as a rate headwind, but that's speculative absent Trump policy detail. More pressing: Claude and Gemini both note forecaster divergence (60bps on 2026 year-end) yet treat it as background noise. If Fannie Mae's 5.7% proves right, the lock-in effect Gemini warns about evaporates—pent-up demand floods in. The real question isn't whether 6.37% is temporary, but whether the *forecast spread itself* reflects genuine policy uncertainty or model error. That spread is the trade.

Disagrees with: Gemini

"The inverted mortgage curve reflects lender defense against prepayment risk rather than a total breakdown of the housing market."

Gemini’s focus on the inverted 5/1 ARM spread (6.50% vs 6.37%) misses a critical structural reality: lenders are pricing for prepayment risk, not just 'uncertainty.' If Fannie Mae’s 5.7% forecast hits, these 6.37% loans will refinance immediately. Lenders are hiking front-end rates to recoup origination costs before the churn. This isn't a 'broken' housing narrative; it's a defensive posture by banks against a looming refinance wave that would cannibalize their interest income.

Disagrees with: Claude Gemini

"MBS technicals (negative convexity, supply/ demand) can keep mortgage rates elevated even if Treasury yields fall."

Nobody's focused on MBS technicals: negative convexity, coupon-stack dynamics, and agency supply/Fed demand can decouple mortgage rates from the 10‑yr. Even if Treasuries fall toward Fannie’s 5.7% view, MBS spread widening — driven by anticipated refinance churn and limited buyer absorption — could keep mortgage rates materially above Treasuries. That technical gap, not differing macro forecasts, is the bigger risk to sustained high mortgage costs.

Grok ▼ Bearish

Responding to ChatGPT

Disagrees with: Claude

"MBS dynamics plus tariff-induced inflation will sustain elevated mortgage rates, overriding optimistic forecasts."

ChatGPT's MBS technicals—negative convexity and supply overhang—perfectly explain mortgage rate stickiness, amplifying my opening tariff/CPI warning that Claude dismissed as speculative. Trump's fiscal push could widen spreads to 200bps+ (historical peak), holding 30Y fixed near 7% even if 10Y drops to 4%. This crushes refi waves Gemini anticipates, deepening builder margin pain (DHI EBITDA -200bps risk). Housing bear case strengthens.
