Estimates use 2025 average rates and are not a loan offer. Your actual rate depends on credit score, lender, loan-to-value, and other factors. Always compare the cash price vs. financed price — contractor financing often hides a 5–10 percent markup in the project cost itself.

Why This Matters

Contractor-promoted '0% for 24 months' financing usually has a bigger margin baked into the project price than you'd see with a home-equity loan. Most homeowners only learn this after they sign. This calculator compares your real monthly payment and total cost across home equity loan, HELOC, personal loan, contractor in-house financing, and 0% intro APR card options — so you walk into the contractor conversation knowing what's actually cheapest.

Frequently Asked Questions

Sometimes — when it is a true 0% APR with no rolled-in markup. Often, the contractor pays a 5 to 10 percent fee to the lender and quietly raises the project price to cover it. Always ask: 'What is the cash price vs the financed price?' If they do not match, you are paying for the financing.

If you have at least 15 percent equity and a credit score above 700, a HELOC or home equity loan typically gives the lowest interest rate (often 6 to 9 percent in 2025). The interest may also be tax-deductible if used for substantial home improvements.

Works well for projects under $20,000 if you can pay it off before the intro period ends (usually 12 to 21 months). If you cannot, the deferred-interest charges retroactively can wipe out any savings. Use it carefully.

A common rule: total home-improvement debt should keep your debt-to-income ratio under 36 percent. For a $20,000 project on a 10-year home equity loan at 8 percent, payments are about $243/month. The calculator shows your specific numbers.
