In year 1, 87% of your payment goes to interest and only 13% reduces your balance.
At this rate, it takes until year 21 before more than half your payment builds equity.
On your $440,000 loan, you'll pay $592,649 in interest - 1.3x what you originally borrowed.
Switching to a 15-year term would cut your interest in half - but raise your monthly payment.

If the payment feels high - a lower home price or larger down payment will move the needle more than a slightly better rate.
If you're close to 20% down - getting there eliminates PMI and meaningfully reduces your monthly cost.
If you're comparing loan terms - a 15-year mortgage costs more monthly but saves significantly on total interest.

At 6.0% your P&I is $2,638/mo. At 6.8% it's $2,868/mo. At 7.5% it rises to $3,077/mo. A small percentage swing causes a large swing in affordability at this price point.
A 30-year payment sits at $2,868/mo, while a 15-year payment climbs to $3,906/mo. The 15-year forces a tighter monthly budget but can save over $100,000 in interest.
A $440,000 loan at 6.8% generates roughly $592,649 in interest. Your $550k home will cost over $1,142,649 by the final payoff date.
