Raising a deductible makes sense when the premium you save each year is more than the extra small losses you expect to pay yourself. It also has to leave room for a bad year without straining debt service or breaking a loan covenant. The smart way to decide is to model it line by line from the loss runs, not to pick a round number because it sounds disciplined. This guide is for new owners deciding how much risk to keep on their own balance sheet after closing.
The short answer
- A deductible is the part of a covered loss you pay. A self-insured retention is similar, but you usually pay or handle the claim yourself before the policy responds.
- Compare the premium credit with the losses you would have kept over the last three to five years, then stress test a bad year.
- Know whether the deductible applies per claim, per vehicle or as an annual aggregate. With a per-claim deductible, how often you have claims matters more than how big they are.
- Check the loan agreement, the lease and key customer contracts before you change anything. Some set maximum deductibles.
- Start where claims are rare and the credit is meaningful. Be careful with percentage deductibles for wind, hail or earthquake.
When does a higher deductible make sense?
A deductible trade is simple: you give the carrier less risk and it charges you less premium. Whether that is a good trade depends on four things.
- Claim frequency. If the business rarely has small claims on a line, a higher deductible costs you little in practice. If it has several small claims a year, you will pay most of the deductible every year.
- The size of the credit. Carriers price deductible credits from their own rating plans. The credit for moving from a very low deductible to a moderate one is often worth more than the credit for moving from moderate to high. Ask for quotes at several levels.
- Liquidity. Right after closing, cash is often tight: working capital was just pegged, the revolver may be partly drawn and debt service has started. Keeping more risk makes sense once you know what a bad year looks like.
- Contract limits. Lenders, landlords and customers sometimes cap deductibles. A saving that breaches a covenant is not a saving.
A higher deductible is a tool for paying less for losses you can predict and afford. It is not a way to save on losses you cannot afford, which is what insurance is for. For the wider order of operations on cost, see how to reduce insurance costs after buying a business.
How do you model the savings against expected small losses?
Use the seller's loss runs (the carrier's claim history reports) for the last three to five years, one line of coverage at a time. See how to read loss runs if they are new to you.
- List every claim on the line with its date and paid or incurred amount. If the loss runs show the carrier's payment after the current deductible, add the current deductible back to get the full size of each loss. Losses below today's deductible may not appear at all, and they do not change the comparison.
- For each deductible option, work out what the business would have paid on each claim: the full claim if it was below the deductible, otherwise the deductible.
- Subtract what you pay at today's deductible to get the extra retained cost per year.
- Compare it with the premium credit the carrier quotes for that option.
- Stress test. Take the worst year in the data, add one more claim at the full deductible, and ask whether the business could pay that without touching the revolver or a covenant.
A quick sense check is the break-even interval: divide the extra amount you would pay on each claim by the annual premium saving. The answer is the break-even gap between claims at or above the new deductible: if such claims come more often than once every that many years, the higher deductible costs more than it saves. For illustration only, if raising a deductible by $9,000 saves $1,800 a year, the answer is five: one claim at or above the new deductible every five years wipes out the saving.
A hypothetical example. A buyer runs 12 service vans. The collision deductible is $1,000, and the carrier quotes a $3,600 annual saving to move to $5,000. Over five years the loss runs show seven collision claims: five above $5,000 and two averaging $3,000.
| Item | Calculation | Amount |
|---|---|---|
| Extra cost on the five larger claims | 5 x ($5,000 minus $1,000) | $20,000 |
| Extra cost on the two smaller claims | 2 x ($3,000 minus $1,000) | $4,000 |
| Extra retained cost per year | $24,000 over 5 years | $4,800 |
| Premium saved per year | Carrier quote | $3,600 |
| Net result per year | $3,600 minus $4,800 | $1,200 worse |
On these illustrative numbers the higher deductible loses money unless the buyer also cuts collision frequency, for example with driver standards and telematics. The same math on a property policy with one small claim in five years could come out the other way.
Per claim, per vehicle or aggregate: which deductible are you buying?
The number on the declarations page means little until you know how it applies. Check the wording on each line.
| Line | How deductibles often work | What to watch |
|---|---|---|
| Commercial property | A dollar deductible per occurrence; business income often has a waiting period that acts as a time deductible | Separate wind, hail, named storm or earthquake deductibles, often a percentage of each building's limit of insurance (or, on some forms, its value) |
| Auto physical damage | Per vehicle, per accident, separately for collision and comprehensive | Several vehicles damaged in one event can mean several deductibles |
| General liability | Many small policies have none; where offered, often per claim, with the carrier paying first and billing you back | Whether defense costs count toward the deductible |
| Workers' compensation | Deductible plans exist in many states, with rules that vary by state | Larger programs usually require collateral, such as a letter of credit. In many states, losses inside the deductible are still reported at full value, so the deductible does not lower your experience mod; ask how your state handles it, and see checking your experience mod |
| Cyber, employment practices and management liability | A retention per claim, sometimes set by the carrier rather than chosen | Whether defense costs count toward the retention, and who controls the defense |
Two other distinctions matter:
- Aggregate deductibles. Some programs cap the total deductibles you pay in a policy year. An aggregate can make a higher per-claim deductible much safer for a business with frequent small claims.
- Self-insured retentions. Under a retention you usually pay the claim, including defense, until the retention is used up, and contracts may treat it differently from a deductible. See deductible vs self-insured retention and defense costs inside vs outside limits.
Deductibles also stack with other policy terms. Under the standard property form, if limits fall short of the coinsurance requirement the claim is cut proportionally and then the deductible comes off. In that form's own example, property worth $250,000 with an 80% coinsurance requirement is insured for only $100,000, half of what it should carry. A $40,000 loss then pays half ($20,000) minus a $250 deductible: $19,750. A high deductible on an underinsured building compounds the hit. See coinsurance.
How much cash should you hold back for deductibles?
Treat retained losses as a budget line and a reserve, not a hope. A practical way to size the reserve:
- Expected year: your modeled retained losses across all lines, built into the operating budget.
- Bad year: the worst year in the loss history at the new deductibles, plus one large claim at the full deductible on your highest-deductible line, plus any percentage deductible on a storm-exposed building.
- Collateral: if a program requires a letter of credit, count it against revolver capacity.
Then check the bad year against the loan. Retained losses usually reduce earnings before interest, taxes, depreciation and amortization (EBITDA). Covenants such as a fixed charge coverage ratio are often calculated from earnings, so check how your loan agreement defines them. If the board or investors approve the risk appetite, record the decision and the reserve in your next update; see insurance reporting to investors. How to account for retained losses and reserves is a question for your accountant.
What will your lender, landlord and customers allow?
Read the insurance sections of your key agreements before you request quotes.
- Lenders. For Small Business Administration (SBA) 7(a) loans, Standard Operating Procedure (SOP) 50 10 8.1 focuses on insuring collateral for full replacement cost with lender protection clauses and cancellation notice. Your loan agreement or the lender's own policy may add a maximum deductible. See SBA lender insurance requirements.
- Landlords. Leases often say who insures the building and may cap the tenant's property deductible. See lease insurance requirements.
- Customers. Contracts sometimes limit deductibles or retentions on general liability, or require that a retention not reduce the customer's protection as an additional insured. See check customer contracts against your policies.
If an agreement is silent, a large change is still worth mentioning to the lender. Surprises in a borrower's insurance tend to cost more goodwill than they save.
Which deductibles should you change first?
A short decision guide:
- Good first candidates: property deductibles on well-protected locations with few claims, and comprehensive deductibles on older vehicles with modest values.
- Model carefully: collision on a fleet with frequent minor accidents, and liability deductibles where the carrier bills you back and defense costs may count.
- Leave for later: workers' comp deductible programs until you understand the payroll, claims and collateral, and any line where small claims are frequent and prevention is the better fix.
Whatever you choose, keep reporting every liability and workers' comp claim, and any property or vehicle loss that could exceed the deductible. A higher deductible does not change the policy's notice conditions, and late notice can put coverage at risk. It also does not erase small claims from the loss runs, so prevention still pays: see safety programs and premium credits and fleet telematics and driver standards. A Morrow review can request quotes at several deductible levels so you can run this model with real numbers; any terms depend on carrier underwriting.

Frequently asked questions
Does a higher deductible keep small claims off my loss runs?
Usually not, for claims you report. Report every liability and workers' comp claim, and any property or vehicle loss that could exceed the deductible, under the policy's notice conditions. Carriers generally record reported claims within the deductible on the loss history. The deductible changes who pays the first dollars, not whether the claim exists.
Can I raise a deductible in the middle of the policy term?
Often, by endorsement, but carriers differ on whether they allow it and how they calculate the credit. Workers' comp deductibles are usually chosen at the start of a policy term, so plan those changes for renewal. Renewal is usually the cleaner time, because you can compare quotes at several deductible levels and align the change with your budget.
Is a self-insured retention the same as a deductible?
Not quite. With a deductible the carrier often handles the claim and bills you for your share. With a self-insured retention you usually pay the claim, including defense, until the retention is used up, and the policy responds after that. Contracts may also treat them differently.
Will my SBA lender let me raise the property deductible?
Check your loan agreement first. SBA's procedures focus on replacement cost limits and lender protection clauses on collateral, and individual lenders may add their own deductible limits. If the agreement is silent, tell the lender before you make a large change.
How big a deductible can a small business afford?
There is no rule. Size it to your liquidity: the business should be able to pay a bad year of retained losses from cash without drawing on the revolver or tripping a covenant. Model it from your own loss history rather than a rule of thumb.
