How Our Home Equity Calculator Works: CLTV Limits & Amortization Math
A complete guide to home equity loans, CLTV eligibility, HEL vs HELOC vs Cash-Out Refi, IRS tax rules, and how every number in this calculator is calculated — step by step.
A Home Equity Loan (HEL) is a second mortgage that lets you borrow a lump sum against the equity you have built in your home. You receive all the funds at once and repay them at a fixed interest rate over a set term — typically 5 to 30 years. Your home is collateral, which is why rates are significantly lower than personal loans or credit cards.
Unlike a HELOC (which is revolving credit), a HEL gives you a single disbursement and a predictable, unchanging monthly payment for the life of the loan — making it ideal for defined, one-time expenses like a major renovation, medical bill, or tuition payment where you know the exact amount needed upfront.
Combined Loan-to-Value (CLTV) is the single most important number lenders use to determine how much you can borrow. It measures the total of all loans secured by your home (first mortgage + any HEL or HELOC) as a percentage of your home’s current market value.
| Formula | Example |
|---|---|
| CLTV = (Mortgage + HEL) ÷ Home Value | ($280K + $80K) ÷ $450K = 80.0% |
| Max HEL = (Home Value × CLTV%) − Mortgage | ($450K × 80%) − $280K = $80,000 |
Every fixed-rate loan — including a home equity loan — uses the same standard amortization formula to determine your monthly payment. This calculator applies this formula exactly as US mortgage lenders do:
| Variable | What It Is | Example (Your Input) |
|---|---|---|
| M | Monthly payment (what you pay each month) | Calculated result |
| P | Principal — your loan amount | $80,000 |
| r | Monthly interest rate = Annual rate ÷ 12 | 7.47% ÷ 12 = 0.6225% / mo |
| n | Total number of monthly payments = Term × 12 | 15 × 12 = 180 payments |
| M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1] | = $80,000 × [0.006225 × (1.006225)¹⁸⁰] ÷ [(1.006225)¹⁸⁰ − 1] = $737.04 / month | |
Each payment splits between interest (your balance × monthly rate) and principal (the rest). Early payments are mostly interest; later payments are mostly principal. This is called front-loaded amortization — and it is why paying just a small extra amount each month early in the loan has a disproportionately large impact on total interest paid and payoff date.

Under IRS TCJA 2017, home equity loan interest may be deductible on Schedule A if you use the funds to buy, build, or substantially improve the home that secures the loan. The $750,000 combined mortgage debt limit applies for joint filers ($375,000 for married filing separately).
| Qualifying Use | Deductible? |
|---|---|
| Kitchen / bathroom renovation | ✅ Yes |
| Room addition or structural work | ✅ Yes |
| Roof, HVAC, foundation repair | ✅ Yes |
| Solar panels or energy upgrades | ✅ Yes |
The TCJA 2017 eliminated the deduction for interest on home equity loans used for purposes unrelated to the home. If you use funds for any of the purposes below, the interest is treated the same as personal loan interest — not deductible, even if the loan is secured by your home.
| Non-Qualifying Use | Deductible? |
|---|---|
| Credit card or personal debt payoff | ❌ No |
| College tuition or education costs | ❌ No |
| Vehicle purchase | ❌ No |
| Vacation or living expenses | ❌ No |
The Consolidation tab answers one question: “Would I actually save money by rolling my high-rate debt into a home equity loan?” The answer is not always yes — even though HEL rates are much lower than credit cards.
| Step | What It Calculates | Why It Matters |
|---|---|---|
| 1. Current debt cost | Estimates total interest if each debt is paid with minimum payments only | Sets the baseline to beat |
| 2. HEL cost | Calculates fixed monthly payment and total interest for the consolidation loan | Your actual new obligation |
| 3. Interest savings | Old total interest − New total interest | The true financial gain (or loss) |
| 4. Monthly payment delta | Sum of old minimums − New fixed HEL payment | Cash flow impact each month |
Most US lenders require a minimum 620 credit score (many prefer 680+), at least 15–20% existing equity in the home, a debt-to-income ratio (DTI) below 43% (including the new payment), and a stable, documentable income history of at least two years. Some lenders go to 50% DTI for strong borrowers.
Home equity loans typically cost between $1,000 and $3,500 in closing fees — far less than a full refinance (which can run 2%–6% of the loan). Common charges include an appraisal fee ($300–$600), title search, origination fee (0–1%), recording fees, and attorney/settlement fee. Some lenders offer no-closing-cost HELs in exchange for a slightly higher rate.
A home equity loan typically closes in 2 to 6 weeks from application. You will need a home appraisal (which can now often be done as a desktop or drive-by), income verification (W-2s, tax returns, pay stubs), and a title search. After closing, federal law gives you a 3-business-day right of rescission — you can cancel for any reason within that window.

Expert Underwriting Tips: Maximizing CLTV & Comparing HELOCs
These tips come straight from how underwriters and loan officers actually look at your file. Use them with the calculator to stress-test your numbers before you ever talk to a lender.
- Try reducing your loan amount until CLTV falls into the green zone.
- If you are above 85%, consider paying your mortgage down a bit longer first.
- Screenshot the CLTV bar and numbers — they are exactly what a loan officer will key into their system.
- Lock monthly payment from the results card, then shorten the term and see the new payment.
- If the 10-year payment is too high, 15 years is often a sweet compromise.
- Remember: you can always pay a 20-year loan like a 10-year one — but not the other way around.
- Choose “Home improvement” in the calculator’s purpose buttons when you are upgrading the property.
- Debt consolidation can be smart if the term is reasonable and you commit not to re-run credit card balances.
- Avoid using HELs for depreciating assets that you could finance with shorter, unsecured loans instead.
- Use the closing cost box to compare true APRs, not just headline rates.
- Watch how total interest and breakeven time change lender by lender.
- Include a local credit union in your mix — they often price aggressively on HELs.
- If you plan to sell or refi soon, shorter terms or interest-only HELOCs might be better.
- If this is a long-term “forever home,” consider slightly higher payments in exchange for a faster payoff.
- Use the amortization schedule to see your balance at the exact year you expect to sell or refinance.
