A mortgage amortization schedule is the month-by-month table showing how each payment splits between interest and principal. It explains why your balance barely moves in the early years: on a 30-year loan, most of the first payments go to interest. Understanding a mortgage amortization schedule is the quickest way to see what a loan really costs, and which choices (term, extra payments, refinancing) change the result.
This article uses a worked Glen Allen purchase example, shows where the crossover point falls, tests what extra payments do, and ends with ten short answers to common questions.

How a Glen Allen Home Loan Gets Paid Down, Payment by Payment
Suppose a buyer in Twin Hickory takes a $400,000 loan on a 30-year fixed rate. Her principal and interest payment is the same number every month for 360 months. What changes is the inside of that payment: the interest portion shrinks and the principal portion grows. That gradual shift is amortization.
By Duane Buziak, NMLS #1110647. When a Wyndham or Innsbrook client brings me a Loan Estimate, this is the page I walk through first, because the schedule answers “where is my money going?” better than the rate does.
A schedule has five basic columns:
- Payment number: 1 through 360 on a 30-year loan.
- Payment: the fixed principal and interest amount.
- Interest: the cost of borrowing for that month.
- Principal: the part that reduces what you owe.
- Remaining balance: the loan amount after that payment.
Escrow is not one of them. Property taxes and homeowners insurance collected with your payment are tracked separately. They never reduce your balance, so a total monthly payment of, say, $3,100 includes money that does not appear in the amortization table at all.
Why interest comes first
Each month, interest is the annual rate divided by 12, multiplied by the balance you still owe. At 6.5%, the monthly rate is 0.065 / 12 = 0.0054167. On a $400,000 balance, that is $2,166.67 of interest in month one. Because the balance is largest at the start, the interest charge is largest at the start. The payment is fixed, so whatever interest does not use up goes to principal, and the lower balance next month produces slightly less interest. The compounding runs in your favor, but slowly.
Worked Dollar Example: A $400,000 Loan at 30 Years vs. 15 Years
The standard payment formula is M = P[r(1+r)^n] / [(1+r)^n – 1], where P is the loan amount, r is the monthly rate, and n is the number of payments. The rates below are illustrations, not quotes. Check current averages at Freddie Mac’s Primary Mortgage Market Survey before relying on them, and note that your own rate depends on credit, down payment, property, and market conditions on the day you lock.
30-year fixed at an illustrative 6.5%
Here r = 0.0054167 and n = 360, so (1+r)^360 is about 6.9918. The payment is 400,000 x (0.0054167 x 6.9918) / 5.9918, which comes to about $2,528 per month.
- Month 1: $2,166.67 interest, about $361.60 principal, balance about $399,638.
- Month 180: about $1,577 interest, about $951 principal. Balance after that payment: about $290,200.
- Month 300: about $710 interest, about $1,819 principal. Balance after that payment: about $129,200.
- Total paid: $2,528.27 x 360, about $910,200, so roughly $510,200 in interest.
Notice that after 15 years of on-time payments, this borrower still owes about 73% of the original loan.
15-year fixed at an illustrative 5.75%
Shorter terms usually price lower, so I use 5.75% here. With r = 0.0047917 and n = 180, the payment is about $3,322. Month one is $1,916.67 interest and about $1,405 principal. Total paid is about $597,900, so interest is roughly $197,900.
The delta
The 15-year payment is about $794 higher per month. In exchange, lifetime interest drops by roughly $312,000 and the loan is gone 15 years sooner. Whether that trade works depends on your budget and reserves, not on the math alone.
One local check on loan size: the 2026 baseline conforming limit is $832,750, which I confirm each year against FHFA’s published limits. A $400,000 loan sits well inside it, and Henrico County falls under the baseline figure, but verify the current number before you plan around it.
Reading Your Schedule: Where the Crossover Point Falls
The crossover point is the first month when the principal portion of your payment exceeds the interest portion. On our 30-year example at 6.5%, that is month 233, a little past year 19. Before that, you are paying more to rent the money than to own the house.
The crossover moves with rate and term. Higher rates push it later, since more of each payment is consumed by interest. Shorter terms pull it earlier: in the 15-year illustration above, principal already exceeds interest by month 37.
Here is the 30-year example at selected months (payment numbers, approximate):
- Month 1: interest $2,167, principal $362, balance $399,638
- Month 60: interest $2,031, principal $497, balance $374,400
- Month 120: interest $1,841, principal $688, balance $339,100
- Month 180: interest $1,577, principal $951, balance $290,200
- Month 240: interest $1,213, principal $1,315, balance $222,700
- Month 360: interest $14, principal $2,515, balance $0
Common misreadings
Two mistakes come up often. First, people treat their full monthly payment as equity-building, when escrow for taxes and insurance does not lower the loan. For the current Henrico County real estate tax rate, check the county’s Finance Department page, since rates are set annually. Second, people assume equity builds in a straight line. It does not; it accelerates.
To get your actual schedule, ask your servicer for an amortization schedule or find it in your online portal. Before closing, compare the figures on your Loan Estimate and Closing Disclosure against what you were quoted. The CFPB explains both documents: the Loan Estimate and the Closing Disclosure.
Extra Payments, Recasts, and Biweekly Plans: What Actually Shortens the Schedule
Add $200 a month to the example loan and the payment becomes $2,728.27. Run the balance down at the same 6.5% and it reaches zero in about 293 months instead of 360. That is roughly 67 months, or 5.6 years, saved. Total interest falls from about $510,200 to about $398,300, a saving of roughly $112,000 on the illustrative numbers.
Three tools get lumped together, and they behave differently:
- Extra principal payments: money applied directly to the balance. It shortens the schedule, but your required payment stays the same.
- Biweekly plans: half-payments every two weeks produce 26 half-payments, equal to 13 full payments a year. The savings come from that extra payment, so you can get the same effect by adding one-twelfth of a payment each month. Some third-party programs charge fees, so read the terms.
- Recast: you make a large lump sum and the servicer re-amortizes the remaining balance, lowering the required payment while keeping your rate and term. Not every servicer offers it, and fees and minimum lump sums vary. FHA and VA loans are often not eligible.
Two safeguards matter. Confirm with your servicer that there is no prepayment penalty, which is uncommon on conventional, FHA, and VA loans but should be verified in your note. And designate extra funds as principal in writing or in the portal; otherwise some servicers may treat them as an early payment of next month’s installment.
Whether extra payments beat investing or holding cash is a personal call. Prepaying earns a guaranteed return equal to your rate, but that money is hard to get back out of the house. Many borrowers prefer to fund emergency reserves first.
If you are weighing scenarios before committing, a soft credit pull mortgage review lets you compare terms without a mark on your report. Duane Buziak uses the NoTouch Credit Pull for this, so you can see how different loan structures amortize before any hard inquiry happens.
How Loan Type Changes the Schedule: Fixed, ARM, FHA, VA, and Refinance Resets
Fixed vs. adjustable
A fixed-rate schedule is calculated once. An adjustable-rate mortgage (ARM) is re-amortized at each adjustment: the servicer takes the remaining balance, the new rate, and the remaining months, and computes a new payment. Take a generic 5/6 ARM, which holds its rate for five years and then adjusts every six months. At an illustrative 6.0% start on $400,000, the payment is about $2,398 and the balance after 60 months is about $372,200. If the rate then resets higher, the payment is recalculated on that $372,200 over 300 remaining months. Rate caps, indexes, and margins vary by product, so confirm current terms before choosing one.
FHA and VA add-ons
FHA mortgage insurance premiums and the VA funding fee affect what you pay and sometimes what you owe, but they are not part of the base principal-and-interest amortization. FHA charges an upfront premium (often financed into the balance) plus an annual premium collected monthly. The VA funding fee varies with down payment and whether it is your first use, and can be financed or paid at closing; exemptions exist for some veterans. Rules change, so verify them as of today at HUD.gov and the VA funding fee page.
Refinancing restarts the clock
Go back to the 6.5% loan. After seven years (84 payments), the balance is about $361,700, so you have repaid only about $38,300 of principal. Refinance that balance into a new 30-year loan, and you begin a fresh schedule where early payments are again mostly interest. At an illustrative 6.0%, month one carries about $1,809 of interest against a $2,169 payment, and your total timeline becomes 37 years unless you choose a shorter term. A cash-out refinance, which Glen Allen Mortgage by Duane Buziak can structure up to 90% of value on eligible programs, adds the cash taken out to that new balance.
Commercial financing
Commercial loans often use interest-only periods or balloon payments, with amortization set longer than the loan term. The schedule can look very different from a home loan, so review it with a broker who handles commercial loans.
Comparison: Loan Term Options and Who Helps You Model Them
Here are four structures on the same $400,000 loan, using the illustrative rates from earlier. Treat each as an example, not a quote.
- 30-year fixed (6.5%): payment about $2,528; total interest about $510,200; crossover at month 233. Best fit: buyers prioritizing the lowest required payment and flexibility.
- 20-year fixed (6.25%): payment about $2,924; total interest about $301,700; crossover at month 108. Best fit: buyers who can handle a higher payment and want a middle path.
- 15-year fixed (5.75%): payment about $3,322; total interest about $197,900; crossover at month 37. Best fit: buyers with strong income and reserves who want the home paid off sooner.
- 5/6 ARM (6.0% start): payment about $2,398 during the fixed period; the lifetime total depends on future adjustments (about $463,400 if the rate never moved, which is unlikely). Crossover about month 222 if unchanged. Best fit: buyers who expect to sell or refinance within the fixed window and can tolerate payment risk.
Modeling these side by side is where the service approach matters. Duane Buziak is a broker who shops hundreds of loan sources at once, and he can offer no hard inquiry mortgage pre approval through the NoTouch Credit Pull, so you can compare real schedules without affecting your score.
Other options exist, and the right comparison is the one you verify yourself:
- Duane Buziak, Glen Allen Mortgage by Duane Buziak: multi-source brokerage; schedules built per scenario; local to Glen Allen, Innsbrook, and Short Pump.
- Courtney Ficken, First Home Mortgage: a local competitor; ask how many programs she can compare and how her scenarios are presented.
- Rocket and Movement: national providers; ask each how they show amortization, whether credit is pulled for a quote, and who your point of contact will be.
Whoever you ask, request the same loan amount, term, and rate assumptions in writing so the schedules are comparable.
Frequently Asked Questions About Amortization Schedules
What is mortgage amortization?
Mortgage amortization is the process of paying off a loan through fixed scheduled payments, each covering interest first and then principal. Early payments are mostly interest, and later payments are mostly principal. On a $400,000, 30-year loan at 6.5%, the payment is about $2,528 throughout.
Why are early mortgage payments mostly interest?
Interest is charged on your remaining balance each month, and the balance is highest at the start. At 6.5% on $400,000, month one has $2,167 of interest and only about $362 of principal. As the balance falls, the interest charge falls with it.
What is the crossover point?
The crossover point is the first month when your principal portion exceeds the interest portion. On a $400,000, 30-year loan at an illustrative 6.5%, it falls at month 233. Higher rates delay it, and shorter terms bring it much earlier, around month 37 on a 15-year loan.
Do extra payments lower my monthly payment?
Extra principal payments usually shorten the loan rather than lower the payment. Adding $200 monthly to the $400,000 example saves roughly 67 months and about $112,000 in interest, but the required payment stays the same. Only a recast or refinance changes the required amount.
What is the difference between a recast and a refinance?
A recast re-amortizes your existing loan after a lump-sum payment, lowering the payment while keeping your rate and term. A refinance replaces the loan with a new one, new rate, new term, and new closing costs. Recasts are cheaper but not offered on every loan.
Is escrow part of the amortization schedule?
No. Escrow collects property taxes and homeowners insurance and is tracked separately from your loan balance. Paying escrow does not reduce principal. Your total monthly housing payment is the amortizing principal and interest plus escrow, so it will be higher than the figure in the schedule.
Is a 15-year or 30-year mortgage better?
Neither is better for everyone. On $400,000 with illustrative rates, the 15-year costs about $794 more monthly but saves roughly $312,000 in interest. The 30-year keeps the required payment lower and cash flow flexible. The right pick depends on your income, reserves, and goals.
How does an ARM change the amortization schedule?
An ARM is re-amortized at each rate adjustment. The servicer applies the new rate to the remaining balance over the remaining months, producing a new payment. If rates rise, more of the payment goes to interest again, slowing principal paydown until the next adjustment.
Can Duane Buziak run an amortization schedule before I apply?
Yes. Duane Buziak, NMLS #1110647, Glen Allen’s Mortgage Broker of the Year for 2025, can build side-by-side schedules for 30-, 20-, and 15-year terms before you apply, including a $400,000 scenario like the one above, using a soft pull so your credit is untouched.
Does GlenAllenMortgage.com offer pre-approval without a hard pull?
Yes. GlenAllenMortgage.com offers mortgage pre approval without hard pull through the NoTouch Credit Pull, so you can see term and payment options without a hard inquiry on your report. Duane Buziak serves Glen Allen, Innsbrook, Short Pump, and nearby Henrico neighborhoods from 4860 Cox Rd.
What the Schedule Tells You About Interest, Equity, and Your Next Move
An amortization schedule shows how interest and equity trade places over time: you start by paying mostly interest and finish by paying mostly principal. The term you choose and the extra principal you add decide how soon that trade happens, and a refinance resets the clock. Seeing your own numbers makes those decisions far less abstract.
