Total cost of risk is the full price your companies pay for risk, not just the premium. It adds insurance premiums and fees, losses you pay inside deductibles, uninsured losses, safety and other risk control spending, and the time your team and advisors spend on insurance and claims. Measured the same way at every portfolio company, it shows where risk dollars go and whether a decision like raising deductibles or combining programs actually saved money. This guide is for holding company owners with two or more businesses who want one number they can manage.
The short answer
- Premium is only one part. Retained losses, uninsured losses, fees, risk control and admin time can move the total as much as price does.
- Measure each company the same way, over the same period, and divide by a common base such as revenue or payroll so companies of different sizes compare fairly.
- Use it to judge decisions: deductible levels, safety spending, one program vs separate policies, and whether alternatives like group captives are worth a look.
- Watch the links between companies. Shared limits and combined workers' compensation experience mean one company's claims can raise the others' costs.
What is total cost of risk?
The International Risk Management Institute (IRMI), a widely used insurance reference, defines cost of risk as the total cost of managing risks and losses. That includes uninsured (retained) losses and the expense of adjusting them, risk control costs, insurance and other risk transfer costs, and administrative costs. In plain terms, it is the full price of being exposed to accidents, lawsuits, theft and damage, whether you pay it to a carrier or out of your own cash.
| Component | What it includes | Where to find it |
|---|---|---|
| Premiums | All insurance premiums after audits and endorsements | Invoices, audit statements, broker summary |
| Fees, taxes and financing | Policy fees, surplus lines taxes where they apply, premium finance interest, broker fees if any | Invoices and finance agreements |
| Retained losses | Losses paid inside deductibles or self-insured retentions | Loss runs (carriers' claim reports), deductible billings |
| Uninsured losses | Losses with no coverage, or above the limits | General ledger, repair invoices, settlements |
| Claim handling costs | Outside adjusters, legal fees you pay directly | Vendor invoices |
| Risk control | Safety training, telematics, cyber tools, inspections | Vendor invoices and budgets |
| Collateral and cash tied up | Letters of credit or deposits for high deductible programs or captives, at your cost of capital | Loan and program agreements |
| Internal admin time | Hours spent on renewals, certificates, audits and claims | A simple time estimate by role |
Not every item has to be precise. A consistent estimate of admin time is far more useful than leaving it out.
Why does premium alone give you the wrong answer?
Premium is the visible part, so it gets managed. The other parts move quietly, and a decision that lowers premium can raise the total.
- Higher deductibles lower premium and raise retained losses. Whether the trade pays depends on claim frequency. See raising deductibles the smart way. Your acquisition model's insurance budget should carry the same split.
- Dropping a line of coverage saves premium until the first uninsured loss, which may be larger than years of savings.
- A lower-priced policy with narrower terms can push more claims onto your own cash through exclusions or sublimits.
- Skipping risk control saves a vendor bill and can cost more in claims, a higher experience modification factor (mod) for workers' compensation and worse renewal terms.
- Admin load grows with every separate policy, renewal date and certificate request across the portfolio.
Total cost of risk keeps all of these on one page, so you can see whether a saving in one place simply moved the cost somewhere else.
How do you measure it across portfolio companies?
Consistency matters more than precision. Set the method once and use it every year.
- Pick one period. Use the fiscal year or one common policy year, and stick with it.
- Tag the costs. Give each component its own account or tag in every company's books so the data rolls up without detective work.
- Value claims consistently. For retained losses, decide whether you count paid amounts only or paid plus reserves (what the carrier expects to pay on open claims), and use the same rule everywhere.
- Estimate admin time. Hours per month by role, times a loaded hourly cost.
- Divide by a common base. Cost of risk per $100 of revenue or per $100 of payroll lets you compare a 20-person company with a 120-person one. Use it to track your own trend, not to compare against published averages, which rarely match your mix of businesses.
A hypothetical example. A holding company owns three businesses. The numbers are illustrative.
| Item | Company A | Company B | Company C |
|---|---|---|---|
| Revenue | $10,000,000 | $6,000,000 | $4,000,000 |
| Premiums, fees and taxes | $180,000 | $90,000 | $70,000 |
| Premiums, fees and taxes per $100 of revenue | $1.80 | $1.50 | $1.75 |
| Retained losses | $20,000 | $45,000 | $5,000 |
| Uninsured losses | $0 | $25,000 | $0 |
| Risk control | $15,000 | $0 | $5,000 |
| Admin time | $10,000 | $10,000 | $5,000 |
| Total cost of risk | $225,000 | $170,000 | $85,000 |
| Per $100 of revenue | $2.25 | $2.83 | $2.13 |
Company B pays the least premium per dollar of revenue ($1.50 per $100), yet it has the highest total cost of risk because of retained and uninsured losses and no risk control. Premium alone would have pointed the board at the wrong company.
What decisions can total cost of risk help you make?
| Decision | What the measure shows | Watch out for |
|---|---|---|
| Deductible levels | Whether premium credits beat the extra retained losses over several years | One quiet year can make a high deductible look better than it is |
| Safety and risk control spending | Whether claim costs and mods fall after the spend | Workers' compensation mods react with a lag of a year or more |
| One program vs separate policies | Combined premium, admin time and shared limits against separate ones | Exit plans; see one program vs separate policies |
| Remarketing | Whether a new program lowers the total, not only the premium | Narrower terms that shift losses back to you |
| Contract risk transfer | Whether making subcontractors carry their own coverage lowers your claims | Certificates are not coverage; check the endorsements |
| Group captives or association programs | Whether the portfolio's retained losses and premium are large and steady enough to consider alternatives | Collateral, shared risk and tax questions for your accountant; see group captives and association programs |
Look at three to five years where you have them. Risk costs are lumpy, and one large claim can swamp a single year.
How can one company's bad year raise costs at the others?
Portfolio companies are not as separate as their legal entities suggest. Two links matter most.
Combined workers' compensation experience. Under the National Council on Compensation Insurance (NCCI) experience rating rules, businesses with more than 50 percent common ownership are combined into a single mod. That means a bad claims year at one company can raise workers' compensation costs at the others. Some states use their own rating bureaus with similar majority ownership concepts, and North Dakota, Ohio, Washington and Wyoming run monopolistic state funds, so confirm how each state treats your group.
Shared limits. If your companies sit on one program, they may share the same aggregate limit (the most a policy pays in a policy period). A large claim at one company can use up limits the others were counting on. Per-location or per-project aggregate endorsements, separate aggregates by named insured, or higher umbrella limits can reduce that risk, depending on what carriers offer. Allocate premium (usually by each company's share of the rating base, such as payroll for workers' compensation and revenue for liability) and track claims by company so the total cost of risk shows who is driving the cost.
For how a holding company should set up its entities and policies in the first place, see insurance for holding companies and roll-ups.
What mistakes distort total cost of risk?
- Counting premium before audit. Use final premium after audits, or the number is understated for growing companies.
- Ignoring open claims. A company with large reserves on open claims has costs coming, even if little has been paid.
- Mixing periods. Policy years and fiscal years that do not line up double count or miss costs.
- Leaving out uninsured losses because they were booked as repairs or legal fees.
- Judging on one year. Use a rolling three-year view.
- Comparing to someone else's averages instead of your own trend.
How should you report total cost of risk to your board?
Keep it to one table and a few sentences. Show each company and the portfolio total, the trend over three years, the split between premium and everything else, and the cost per $100 of revenue. Call out large one-off losses separately so they do not hide the underlying trend, and pair every number with the action you took or propose. See how to report on insurance to your investors and board for the wider report.

Frequently asked questions
What is a good total cost of risk for a small business?
There is no reliable benchmark that fits every mix of businesses. The useful comparison is your own trend over several years and between your own companies, measured the same way. A falling cost per $100 of revenue with stable coverage is the goal.
Should I include my own time managing insurance?
Yes, as an estimate. Hours spent on renewals, certificates, audits and claims are a real cost, and they often fall when programs are consolidated. A consistent rough estimate is better than leaving it out.
Can one portfolio company's claims raise costs for the others?
Yes. Under NCCI experience rating rules, businesses with more than 50 percent common ownership are combined into one workers' compensation mod, and companies on one program may share aggregate limits. Track claims by company so you can see who is driving the cost.
How often should I calculate total cost of risk?
Once a year is enough for most small holding companies, ideally a few months before the main renewal so the results can shape deductible and program decisions. Update it when you add a company.
Is total cost of risk the same as my insurance budget?
Not quite. The insurance budget in your acquisition model forecasts premium, audits, fees and the losses you expect to pay inside deductibles. Total cost of risk looks back at what risk actually cost: it adds claim handling, risk control, collateral and admin time, and counts uninsured losses as they really happened, including large ones a budget rarely plans for. Use the budget to plan and total cost of risk to judge the results.
