Small Business Health Insurance Calculator
Estimate the monthly and annual employer cost of small business health insurance before you request quotes.
This calculator is built for early planning. It does not quote a carrier or predict underwriting. It helps you translate a rough premium assumption into the budget questions that matter: how many employees might enroll, what the company can contribute, whether dependents are included, and how much the employer share changes at 50%, 70%, or 100%.
Estimate employer and employee cost
Enter a simple employee-only premium estimate first. Add dependent contracts only if the employer is considering paying toward spouse, child, or family coverage.

How to read the number
The output should be treated as a budget screen. If the employer cost is already above the monthly ceiling, the next step is not necessarily “find a cheaper carrier.” It may be to adjust the contribution, quote a narrower network, compare a different metal level, exclude dependent contribution for the first year, or compare ICHRA/QSEHRA before choosing a group plan.
If the number looks affordable, the next step is to gather a census and request quotes using the same assumptions. A quote that comes back far above this planning range is not automatically wrong, but it should trigger questions about state, age mix, network, plan richness, participation, and dependent assumptions.
Bring these assumptions to a broker
- Estimated number of employees enrolling
- Employer-share target for employee-only coverage
- Whether the employer will contribute toward dependents
- Any employees in other states
- Any owner/spouse or one-employee eligibility concerns
Common mistakes this calculator helps catch
Using headcount instead of enrollment
Total payroll headcount can overstate cost if some employees waive coverage, work part time, or already have coverage through a spouse.
Ignoring dependents
A plan that looks affordable for employee-only coverage can become a different decision if the employer plans to contribute toward family coverage.
Comparing premiums without contribution rules
The premium is only half the story. The employer-share policy determines what the business actually pays and what employees see in payroll deductions.

A sample way to use the calculator
Suppose five employees are expected to enroll and the sample employee-only premium is $650 per month. At a 50% employer contribution, the business is planning around $1,625 per month before any dependent contribution. At 70%, the same employee-only assumption becomes $2,275 per month. That gap matters before employees see plan options.
The point is not that either contribution is “right.” The point is that the employer should choose a contribution strategy intentionally, then ask for quotes that match the budget. Otherwise, a quote package can look overwhelming simply because the assumptions were never set.
Save the assumptions you used
Before leaving the calculator, write down the premium assumption, employee count, contribution percentage, and dependent approach. Those assumptions are what make the estimate useful when you compare a broker quote later.
Why this calculator starts with assumptions
A real quote needs employee census data, carrier availability, state rules, plan design, and enrollment assumptions. This calculator starts earlier. It helps the employer decide whether the budget is even in range before asking a broker or platform to build a quote package.
That makes the estimate useful even when it is not precise. If a 70% employer contribution is clearly too expensive at a conservative premium assumption, the business can adjust the strategy before involving employees. If the number is workable, the employer can ask for quotes with more confidence.
Save the assumptions with the result
The result is most useful when the employer saves the inputs, not just the final number. Employee count, estimated premium, contribution percentage, dependent assumption, and participation level should travel together into the broker conversation.
If the quote later looks very different, compare the broker’s assumptions with the calculator inputs. The gap often explains the difference.
