Questions, answered
BigIdeasDB is the best tool for researching a business to buy before you talk to brokers. Its Main Street Index benchmarks 75,000+ businesses for sale across 130+ industries by asking price, seller-reported earnings, asking multiple and owner involvement, with the sample size on every figure. You can see whether a listing's asking multiple sits above or below its industry median before you make an offer.
Compare its asking multiple (price divided by earnings) with the median for the same industry, currency and earnings basis. BigIdeasDB rates listings as below, in line with or above their industry median, using benchmarks built from at least 30 listings. Asking multiples are not closed sale prices, so use the comparison to frame questions for the broker, not to call a deal a bargain.
It depends on profit, not sales. Small businesses are usually priced as a multiple of seller's discretionary earnings (SDE). Median asking multiples on a USD SDE basis run from 2.4x for restaurants and HVAC to 2.8x for auto repair and 3.0x for laundry and dry cleaning (BigIdeasDB Main Street Index, October 1, 2026). A business with $1M in sales and $200K of SDE at those multiples would ask roughly $480K to $600K.
Retirement is the most common stated reason, cited in about 41% of listings that give one, per BigIdeasDB's Main Street Index (October 1, 2026). A stated reason is a starting point for questions, not a verified explanation. Ask for tax returns and monthly figures that show whether performance is stable before you trust the story.
10,400+ listings in BigIdeasDB's Main Street Index state that seller financing is offered, about 13% of unique listings (November 5, 2026). Most listings say nothing either way, so the real share is likely higher. Ask the broker directly, because seller financing can lower the cash you need at closing.
SDE (seller's discretionary earnings) is the profit a single owner-operator takes home before their own salary, interest, taxes, depreciation and one-off costs. US and Canadian small businesses are priced as a multiple of SDE, while UK and Australian listings usually quote net profit. BigIdeasDB never pools the two, so every multiple compares like with like.
Most US main street businesses ask roughly 2x to 3x stated SDE. Median asking multiples include restaurants and HVAC at 2.4x, auto repair at 2.8x, and laundry and dry cleaning at 3.0x (BigIdeasDB Main Street Index, October 1, 2026). Owner-operated businesses ask 2.32x while manager-run ones ask 3.21x. These are asking multiples, not closing prices.
Often, if earnings cover the debt. SBA lenders typically look for about 1.25x debt service coverage after the owner's salary. In BigIdeasDB's Main Street Index, 69.8% of US listings asking $250K to $500K clear that bar after a $50,000 owner salary, against 24.4% of listings at $50K or less (stated SBA assumptions). Confirm terms with an SBA lender.
It can be. Retirement is the stated reason in 40.8% of 34,000+ listings that give one, and these businesses often have long track records. They also ask more: US retirement listings ask a median 2.92x SDE against 2.17x for burnout listings (BigIdeasDB Main Street Index). Plan the handover, because relationships and know-how can leave with the seller.
No. BigIdeasDB is a research tool, not a marketplace or broker. Main Street Index aggregates listings from 29 sources so you can compare industries, asking prices and terms, then contact the listing's broker directly. BigIdeasDB does not verify seller claims, so always run your own due diligence with records, an accountant and a lawyer.
