Estimate the monthly payment and total interest if you finance a large plumbing repair such as a sewer line or repipe.
Big plumbing failures, such as a collapsed sewer lateral, a whole-house repipe or a slab leak, can run into the thousands of dollars. Contractors sometimes offer financing on the spot, and homeowners also use personal loans, credit cards or home equity products. This calculator shows what a standard fixed-rate instalment loan would cost.
Formula: monthly payment = P x r / (1 - (1 + r)^-n), where P is the amount financed, r is the monthly rate (APR divided by 12) and n is the number of monthly payments. Total interest is monthly payment times n, minus P. The upfront fee is added to total paid.
Worked example (illustrative numbers): $8,000 at 11 percent APR over 3 years gives a payment of about $262 a month and roughly $1,430 of interest, plus the $100 fee. Stretching the same loan to 5 years lowers the payment but raises total interest.
Compare the contractor's financing offer with at least one outside quote. Watch for deferred-interest promotions, where interest is charged back to day one if the balance is not cleared in time, and for dealer fees that raise the price of the work. The calculator does not model variable rates, home equity tax treatment or credit-card minimum payments. The Consumer Financial Protection Bureau publishes plain-language borrowing guides worth reading first.
