The “rate” on an equipment loan is not the full cost. Total cost of ownership (TCO) includes the principal, total interest paid, all fees, insurance, maintenance, and the tax-savings offset. Here is how to calculate it properly.
What the rate misses
A 10% APR equipment loan costs more than 10% of the principal each year. Over the term, you pay back the principal PLUS the interest, PLUS fees, PLUS insurance and maintenance. The APR alone tells you the borrowing cost; TCO tells you the all-in cost.
Five components of TCO
1. Principal + interest
From the amortization schedule. For a $100,000 loan at 10% APR over 60 months, total payments are $127,482 (principal + $27,482 interest).
2. Fees
- Origination fee: typically 1-3% of principal. Sometimes financed into the loan (so you pay interest on it).
- Doc fee: $150-500 flat.
- UCC filing fees: $20-100 depending on state. Usually included in doc fee.
- Title fees: on titled equipment. State-specific.
- Late fees: usually 5% of payment or $25, whichever is greater.
- End-of-lease return / inspection: on FMV leases. $250-1,500.
3. Insurance
The lender requires you to maintain insurance on the equipment with the lender named as loss payee. For a $100,000 piece of equipment, expect $800-2,000/year depending on type and use. Over 5 years, that is $4,000-10,000.
4. Maintenance and operating costs
Variable by equipment type. For example, a $100,000 dump truck has fuel, oil, tires, brakes, regulatory compliance (DOT, IFTA), and roughly 5-10% of value per year in maintenance. For a CNC machine, maintenance might be 3-5% of value annually. Compute this separately if you are comparing keep-and-fix-old-equipment vs buy-new options.
5. Tax-savings offset
The tax deductions reduce your effective TCO:
- Section 179 + bonus depreciation in year of placed-in-service: at a 25% blended tax rate, a $100,000 equipment purchase saves $25,000 in taxes in year one (subject to caps and income limits).
- Interest expense deduction over the term: total interest deducted at your tax rate. On $27,482 of interest at 25%, that is $6,871 over the term.
Sample TCO calculation
$100,000 equipment, 60-month loan, 10% APR, 2% origination, $500 doc, $1,500/year insurance, 25% tax rate:
- Principal + interest: $127,482
- Origination (financed): adds ~$2,500 + interest on it
- Doc fee: $500
- Insurance over 5 years: $7,500
- Tax savings (§179 first-year + interest deductions): -$31,871
TCO ~= $106,111
So a “10% APR loan” on $100,000 of equipment actually costs ~$106K all-in over 5 years after tax savings. The effective cost is closer to 1.2% per year on capital deployed (much less than the headline 10%).
Why this matters
- Comparing loan vs lease: the TCO comparison can reverse the “obvious” answer. A higher monthly payment on a loan may have lower TCO due to tax treatment.
- Comparing keep vs replace: if you compute TCO of new equipment vs the maintenance burden of old, the math may favor replacement sooner than intuition suggests.
- Negotiating with the lender: a 0.5-point rate reduction on a $100K loan saves ~$1,400 over 5 years. That is real money but smaller than negotiating away a 2% origination fee.
