By the end of this guide, you will know how much interest and time an extra monthly payment can save on your Henrico County mortgage, using a mortgage payoff calculator with extra payments. Have your latest mortgage statement on hand (balance, rate, payment, escrow) and set aside about 15 minutes. Duane Buziak, NMLS #1110647, walks through each step with a worked example at a Short Pump price point: a $520,000 home with a $494,000 loan. The rate in that example is an illustration as of October 2026, not a quote.
Step 1: Gather Your Loan Details From Your Mortgage Statement
Written by Duane Buziak, NMLS #1110647 | Coast2Coast Mortgage LLC NMLS #376205
A payoff calculator is only as accurate as what you type into it. Pull four numbers from your statement or servicer portal:
- Current principal balance: the amount you still owe, not the original loan amount.
- Interest rate: the note rate, not the APR.
- Remaining term in months: a loan closed in 2022 on a 30-year term has roughly 330 months left today, so check the statement instead of guessing.
- Principal-and-interest (P&I) payment only: your total payment minus the escrow portion.
The fourth number is where most people go wrong. Your monthly bill is usually PITI: principal, interest, taxes, and insurance. Taxes and insurance sit in escrow, and they do not reduce your balance. If you enter the full PITI amount, the calculator treats the escrow money as if it were paying down the loan. It will overstate your payment and show a payoff date that is too early.
Two more checks before you move on. First, confirm whether the loan is fixed or adjustable. An adjustable-rate loan changes its payment when the rate resets, so any projection is only good until the next adjustment. Second, find your servicer’s policy on how extra funds are applied. Some apply them to principal automatically, and some hold them or apply them to the next scheduled payment. Look in the servicer’s payment FAQ or call, and verify the current policy rather than relying on an old statement.
Step 2: Choose a Calculator and Enter Your Baseline Numbers
Look for a calculator with separate fields for a monthly extra amount, a one-time lump sum, and a yearly or biweekly extra. Many basic tools offer only a monthly add-on, which is enough for one scenario but not for comparing strategies in Step 4. A spreadsheet with a standard amortization formula works just as well if you prefer to see every row.
Enter your baseline first, with zero extra. Compare the calculator’s payoff date and total remaining interest against the amortization schedule your servicer provides. They should match within a few dollars. If they are far apart, the likely culprits are an escrow-inflated payment, a rate typed incorrectly, or a remaining term entered in years instead of months. Fix that before running any scenario, because every later result builds on it.
The Consumer Financial Protection Bureau explains how escrow accounts work, which helps you see what to strip out of your payment. In Henrico County, real estate tax is an escrow item and stays outside the calculator’s P&I math. The county has levied $0.87 per $100 of assessed value in recent years, but confirm the current rate on the Henrico County Department of Finance site, since rates are set annually. On a $520,000 assessment, that rate works out to roughly $4,500 a year, or about $377 a month. That is real money leaving your account, but it will not shorten your loan by a day.
Step 3: Run the Extra Payment Scenarios and Read the Results
Here is the worked example. Suppose you buy a $520,000 Short Pump home with 5% down ($26,000), leaving a $494,000 loan. At an assumed 6.25% fixed rate over 30 years, the P&I payment is about $3,042. Left alone, the loan costs roughly $601,000 in interest over 360 months. In the first month alone, about $2,573 of your payment is interest and only about $469 reduces principal.
Now add a principal-only extra each month. These figures are approximate and assume the extra starts with the first payment:
- +$100 per month: payoff in about 329 months (27 years, 5 months), roughly 31 months sooner, with about $61,000 less interest.
- +$250 per month: payoff in about 293 months (24 years, 5 months), roughly 67 months sooner, with about $131,000 less interest.
- +$500 per month: payoff in about 250 months (20 years, 10 months), roughly 110 months sooner, with about $211,000 less interest.
The key terms behind those numbers:
- Amortization: the schedule that splits each payment between interest and principal, with interest heavy early on.
- Principal-only payment: money applied straight to your balance instead of to future scheduled payments.
- Interest saved: baseline total interest minus total interest with the extra.
- Payoff date: the month the balance reaches zero.
Read three outputs for each run: the new payoff date, total interest saved, and months removed. Then test a one-time lump sum against a recurring extra. In this example, a single $10,000 payment at the start (a bonus or tax refund) trims about 20 months and saves roughly $52,000 in interest. That is a strong result for one transfer, though a sustained $100 a month for the whole loan saves more in total.
Step 4: Compare Extra Payment Strategies Side by Side
Monthly extras are one option. Biweekly payments, an annual lump sum, and refinancing to a shorter term each work differently. The same $494,000 example frames the comparison:
| Strategy | How it works | Typical effort | Interest impact | Pitfalls |
|---|---|---|---|---|
| Monthly extra | Add a fixed amount to principal with each payment | Low once automated | +$250 a month saves about $131,000 in the example | Must be marked principal-only; easy to skip in a tight month |
| Biweekly payments | Pay half the payment every two weeks, making 26 half payments, or 13 full ones, per year | Low to moderate | Similar to adding about $253 a month in the example | Some servicers hold partial payments or charge enrollment fees |
| Annual lump sum | One principal payment from a bonus or refund | Low, but irregular | $10,000 once at the start saves about $52,000 | Depends on cash arriving each year; timing matters |
| Refinance to a shorter term | Replace the loan with a 20- or 15-year loan | Higher: application, appraisal, closing costs | Largest, since the rate and term both drop | Higher required payment; a commitment, not an option |
On biweekly plans, confirm the servicer’s handling before you enroll. Some hold each half payment until the second arrives, so the money sits idle. Others charge a setup or per-payment fee. You can often get the same result by adding one-twelfth of a payment to each monthly payment, with no third party involved.
Two principles explain the results. The earliest extra dollars save the most, because interest is calculated on the remaining balance and a dollar removed in year one stops accruing interest for decades. And the benefit depends on your rate. At 6.25%, every dollar of prepaid principal earns a guaranteed 6.25% return, which is attractive. On a loan at 3%, the same dollar earns far less, and other uses of cash may win.
Step 5: Confirm Your Loan Allows Extra Payments and Applies Them Correctly
A prepayment penalty is a fee for paying off a loan early or paying down a large amount. They are rare on conventional, FHA, VA, and USDA loans, but check the note and closing documents for your specific loan. The CFPB explains what a prepayment penalty is and where to find one in your paperwork.
Loan type matters here:
- FHA: these loans are generally prepayable. Check the servicer’s rules on payoff timing and how interest is calculated for the month in which you pay. The HUD.gov FHA loans page is the starting point for program rules.
- VA: there is no prepayment penalty on VA loans. The VA.gov home loans page covers program details.
Do not assume extras go to principal automatically, because not every servicer does that. Mark them clearly:
- Use the servicer’s online “additional principal” option if it has one.
- Otherwise, send a separate payment (or a separate check) with “principal only” and your loan number in the memo.
- Do not fold the extra into the regular payment unless the servicer confirms it will be applied correctly.
Then verify. Your next statement should show the principal balance lower than the amortization schedule predicted, by roughly the extra amount. If the extra was applied to next month’s payment instead, you will see a “paid ahead” notation and no drop in principal. Call the servicer, ask for the payment to be reapplied as principal-only, and request written confirmation. A paid-ahead extra saves nothing, because interest keeps accruing on the full balance.
Step 6: Decide Whether Extra Payments Beat Refinancing or Other Uses of Cash
Compare your mortgage rate with what the same dollar could do elsewhere. Credit card or auto debt above your mortgage rate should be paid first. An emergency fund usually comes before aggressive prepayment, because home equity is hard to get back out in a hurry. Employer retirement matches typically beat a 6% guaranteed return. After those, extra principal is a solid, low-risk use of cash.
A rate-and-term refinance to a 20- or 15-year term is the other route. The tradeoff is flexibility. Extra payments are optional, so you can pause during a lean month. A shorter term is a commitment to a higher payment every month. Many Short Pump owners get most of the benefit by taking a longer term and paying extra voluntarily. If rates have fallen below your current note rate, a refinance may also lower your cost per dollar of principal.
Duane Buziak shops 500+ wholesale lenders as a broker and can run a refinance quote using the NoTouch Credit Pull, a soft credit pull mortgage option. That means a no hard inquiry mortgage pre approval, a mortgage pre approval without hard pull, and a soft pull mortgage broker process, so you get a no credit hit mortgage application while you compare. Structurally, a broker with that many wholesale options can price your file against many programs. Retail lenders usually offer one shelf of their own products, so you see one answer instead of many.
Loan size matters too. The FHFA 2026 conforming loan limits are $806,500 baseline and $1,249,125 in high-cost areas. With Henrico median prices around $520,000 to $527,000, most Short Pump purchase loans sit well inside the baseline. That keeps conventional refinance options wide open.
Step 7: Set Up Your Plan and Review It Each Year
Automate the extra amount so it leaves your account right after the regular payment. Money you have to remember to send tends not to get sent. Pick a number you can sustain, even if it is only $100, and raise it when your income does.
Set a calendar reminder once a year, ideally around your statement anniversary, to rerun the calculator with the updated balance. Also rerun it after any rate change on an adjustable loan, after a refinance, or after a recast. A recast re-amortizes your remaining balance after a large lump sum, lowering your required payment without changing the rate or term. Ask your servicer whether it offers one, what the minimum lump sum is, and what the fee is. Recasts are commonly available on conventional loans, but FHA and VA loans often do not offer them.
Keep a simple tracker with three columns: month, statement balance, and the calculator’s projected balance. If the actual balance runs ahead of the projection, your extras are working. If it runs behind, an extra may have been misapplied, or an escrow change may have altered your payment. A Henrico tax reassessment changes your escrow and total payment but not your P&I, so the tracker helps you tell those apart.
Check Your Next Statement, Then Price a Refinance
Once your first extra payment posts, confirm that your next statement shows the principal drop. If it does, the plan is working. If it does not, call your servicer and have the payment reapplied. After that, it is worth asking whether a refinance would let your extra dollars work harder.
