Price Discovery Range Calculator

No single comp gives the 'right' price. Median ± stdev defines a supportable band. This calculator builds the range from up to five comps.

How the math works

Price band = mean ± stdev. Covers ~68% of distribution. Within band = supportable; outside = needs explanation.

Use median for central tendency (robust to outliers); use mean/stdev for spread. Both together tell the full story.

How this calculator works

What this page estimates

This Price Discovery Range Calculator is built to give a quick, browser-based estimate for price discovery range. No single comp gives the 'right' price. Median ± stdev defines a supportable band. This calculator builds the range from up to five comps. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the price discovery range result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this price discovery range estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

How to Use

Enter 5 comp sale prices per SF (or per door).

Frequently Asked Questions

How many comps?

3-5 minimum for statistical validity. More (8-15) for institutional acquisitions. Each comp should be <6 months old, similar class, within 1-mile radius for multifamily, 2-mile for retail/office.

What's 'reasonable' range?

Within 1 stdev of median is typical. Properties outside this range need explanation — superior location, recent renovation, distress, etc. Institutional buyers stay in tight bands.

How to adjust comps?

Use Comps Adjustment Calculator for structural adjustments (unit mix, amenities, age). This calculator handles the statistical distribution after adjustments.

What does competitive benchmarking look like?

Pull 3-5 comparable properties or units in your submarket from CoStar, Yardi, CIM, or your local broker. Normalize by unit type, class, and age. Your outputs should fall within one standard deviation of the comp-set mean. Outliers are either opportunities or warning signs — dig into why. Monthly benchmarking keeps your portfolio on-market and pricing sharp.
