Estimate the monthly payment on a home improvement loan, HELOC, or personal loan for your renovation.

How we calculated this

Standard amortization formula:

M = P × [r(1+r)^n] / [(1+r)^n − 1]

Where M = monthly payment, P = principal (loan amount), r = monthly interest rate (APR ÷ 12 ÷ 100), and n = total number of monthly payments (term in years × 12).

Important disclaimer This calculator provides estimates for educational purposes only. Actual loan terms, rates, and payments depend on your credit profile, lender, and loan type. Always consult with a licensed lender before making borrowing decisions. We are not a lender and do not provide financial advice.

The calculator above gives you a baseline. To see what you'd actually qualify for, check rates from multiple lenders , most show pre-qualified rates with a soft credit pull that won't affect your score.

Understanding renovation financing options

There are four mainstream ways to pay for a renovation when you can't (or shouldn't) cover it in cash. Each has a different cost structure, speed, risk profile, and ideal use case.

1. Personal Loans

Unsecured installment loans with a fixed rate and fixed term, typically 2 to 7 years. No collateral required , the lender approves you based on credit, income, and existing debt. Rates run higher than secured options (often 7 to 13 percent in 2026), but funding is fast: 1 to 7 days from application to deposit. No appraisal, no closing costs, no risk of losing your home if you default. The simplest option for projects under $50,000.

Best forSmaller projects ($5k–$50k), fast timelines, borrowers with strong credit who don't want to tap home equity.

2. HELOCs (Home Equity Line of Credit)

A revolving line of credit secured by your home's equity. Variable interest rates (often 7 to 10 percent in 2026), with a 5 to 10 year draw period where you borrow as needed and pay interest only, followed by a 10 to 20 year repayment period. Much cheaper than personal loans because your home is collateral. Setup takes 30 to 60 days and involves an appraisal. Best when project costs are uncertain or phased , you only borrow what you actually spend.

Best forLarger projects ($25k+), phased renovations, homeowners with significant equity and steady income.

3. Cash-Out Refinance

Replaces your existing primary mortgage with a new, larger one and gives you the difference in cash. Makes sense only when current rates are at or below your existing mortgage rate. Comes with full closing costs (typically 2 to 5 percent of the new loan amount), so the project usually needs to be large , $75,000 or more , for the math to work. The lowest interest rate of any option when the rate environment is favorable, but you're extending the debt over 15 to 30 years.

Best forMajor renovations ($75k+) when current mortgage rates are below your existing rate.

4. Credit Cards

A 0 percent introductory APR card (typically 12 to 21 months) can work for small projects you'll pay off fast , under $10,000. After the intro period, rates jump to 18 to 29 percent, which is the worst rate you'll find anywhere. Avoid credit cards for anything you can't pay off before the intro APR expires. Useful as a short bridge during a project, dangerous as long-term financing.

Best forSmall projects under $10k with a clear payoff plan inside the intro APR window.

Frequently asked questions

What’s a typical interest rate for a remodel loan?

Unsecured personal loans for home improvement typically range from 7 to 13 percent APR in 2026, depending on credit. HELOCs sit lower, often 7 to 10 percent variable, because they're secured by your home. Cash-out refinance rates track first-mortgage rates plus a small premium. The single biggest factor is your credit score: borrowers with a 760+ FICO often see rates 3 to 5 percentage points lower than those in the 640 to 680 band. Always pull quotes from at least three lenders , soft-pull pre-qualifications won't hurt your score.

Personal loan vs HELOC for renovations: which is better?

Personal loans are faster (often funded in 1 to 7 days), unsecured, and have fixed rates and terms, but they cost more in interest. HELOCs are cheaper because your home is collateral, but they take 30 to 60 days to set up, carry variable rates, and put your home at risk if you default. Rule of thumb: for projects under $25,000 and a fast timeline, personal loans win. For projects over $50,000 where you can wait 30 to 60 days, HELOCs usually save thousands in total interest. For something in between, run both numbers through this calculator and compare totals.

How does my credit score affect my rate?

Credit score is the single largest input to your APR. On a $30,000 personal loan over 5 years, the difference between an 8 percent rate (great credit) and a 13 percent rate (fair credit) is roughly $80 per month and about $4,800 in total interest over the life of the loan. Most lenders offer their best rates to borrowers with FICO scores of 740 or higher. If you're below 680, expect to pay 11 to 18 percent or get rejected; consider improving your score before borrowing for non-urgent projects. Even a 20-point score bump can save thousands.

Can I deduct renovation loan interest?

Sometimes. Under current IRS rules, interest on a HELOC or home equity loan is tax-deductible only if the funds are used to "buy, build, or substantially improve" the home that secures the loan, and only if you itemize. Personal loan interest for home improvement is generally not deductible. Cash-out refinance interest follows the same rule as HELOCs: deductible if the cash-out portion is spent on qualifying improvements. This is a tax-strategy question, not a calculator question , always confirm with a tax professional before borrowing on the assumption of a deduction.

Should I use cash or borrow for a remodel?

If you can pay cash without draining your emergency fund (3 to 6 months of expenses) and without selling investments at a loss, cash is almost always cheaper than borrowing. But if borrowing lets you keep liquidity, capture investment returns above your loan APR, or finance a project that will return more in home value than it costs in interest, financing can make sense. The break-even is usually around 6 to 8 percent APR , below that, the math often favors borrowing for the right projects. Above that, paying cash typically wins.
