Every CostNYC estimate is built the same way, so you can judge how much to rely on it.
1. Collect real prices
We collect prices from provider price lists and websites, government fee schedules (MTA, Port Authority, NYC Clerk, Department of Finance), market data, industry surveys and quotes gathered from New Yorkers. We prefer primary sources and link to them at the bottom of each guide.
2. Build a baseline and adjust for NYC
For each service we set a baseline price for a typical job, then apply adjustments that measurably change the price in New York:
- Location: borough or suburb multipliers (Manhattan is usually 10–40% above the outer boroughs).
- Provider tier: value, mid-market and premium providers.
- Scope and complexity: size, materials, number of items or sessions.
- NYC rules: taxes, tolls, building requirements, licensing and legal fees.
3. Show a range, not just a number
Each calculator shows a single estimate plus a likely range. The range reflects normal variation between providers for the same inputs. Quotes outside it aren't necessarily wrong, but they're worth asking about.
4. Review and update
Guides are reviewed at least twice a year, and immediately when a public fee changes (for example annual toll increases). The "Updated" date on each guide shows the last review.
Limits of an estimate
Estimates are for planning and comparison only. They aren't quotes, medical advice or financial advice. Prices for medical and dental procedures depend on an in-person evaluation; always get written quotes and confirm insurance coverage with your plan.
