How much does deck financing add to the total project cost in interest in NB?

Deck financing costs in New Brunswick vary widely depending on the lender and loan type, but you can realistically expect to pay 20-50% more than the original project cost over the life of a typical loan.

Here's what that looks like in real numbers. A $15,000 composite deck financed over 5 years at 8-10% interest (a common range for home improvement loans through Canadian banks) adds roughly $3,200-$4,200 in interest — bringing your total paid to $18,200-$19,200. At higher rates (12-15%, common with contractor financing programs or unsecured personal loans), that same $15,000 deck costs you $22,000-$24,000 by the time it's paid off. The rate you qualify for depends heavily on your credit score, home equity, and lender.

Common Financing Options for NB Homeowners

Home equity line of credit (HELOC) is typically the lowest-cost option if you have equity built up. Rates currently run around 6-7% in Canada, and interest is only charged on what you draw. On a $15,000 deck paid back over 3 years, you'd pay roughly $1,400-$1,600 in interest — the cheapest borrowing route available to most homeowners.

Personal loans through your bank (RBC, TD, Scotiabank, etc.) typically run 8-12% for creditworthy borrowers. These are unsecured, so no home equity required, but rates are higher. Expect to add $2,000-$5,000 in interest on a mid-sized project depending on your term.

Contractor financing programs are convenient but often carry the highest rates — sometimes 15-29% through third-party lenders. Always read the fine print. Some offer "deferred interest" promotions that backload charges if you don't pay in full before the promotional period ends.

Credit cards should generally be avoided for large deck projects unless you're paying the balance within 1-2 months. At 19-22% interest, a $10,000 deck carried for 3 years costs you an extra $3,500-$5,000 in interest alone.

NB-Specific Consideration Worth Knowing

Because NB decks require proper frost footings (1.2-1.5m deep depending on your region), structural framing, and code-compliant railings, there's less room to cut corners to reduce the financed amount. A deck built cheaply to lower the loan amount often costs more in repairs within 5-7 years — potentially while you're still paying off the original loan.

Practical tips for minimizing financing costs: Get 3 quotes before financing anything — NB deck prices vary enough that the right contractor can save you $2,000-$4,000 upfront. Consider phasing the project (build the main deck now, add the pergola or stairs next season) to reduce the amount financed. And if you're a homeowner with equity, talk to your bank about a HELOC before accepting contractor financing.
