Buy or Lease? A Practical Framework for Capital Decisions
Every few months an owner asks me the same question: buy the workshop or rent it? Purchase the machine or lease it? This article gives you a framework for deciding with numbers rather than instinct, and explains the tax effect of each option.
Why instalment versus rent is the wrong comparison
The most common mistake is comparing the monthly loan instalment with monthly rent, finding them similar, and concluding that buying wins because at least it becomes ours.
The two figures are not the same kind of number:
- A loan instalment mixes principal repayment, which converts cash into an asset you own, with finance cost, which is a genuine expense.
- Rent is entirely a period expense, but it locks no capital into an asset.
The correct comparison is total cost of ownership against total cost of leasing over the same horizon, adjusted for residual value and the cash each option ties up.
Costs that get forgotten on the buy side
When I review an owner's spreadsheet, these items are usually missing:
| Cost item | Note |
|---|---|
| Opportunity cost of the down payment | What would that cash earn inside operations? |
| Financing cost | Interest and fees over the full term, not the headline rate |
| Maintenance and repairs | Grows quickly on used machinery |
| Insurance and municipal charges | Fire cover, vehicle cover, local levies |
| Transfer taxes and registration | Transfer duties, VAT on purchase, legal fees |
| Downtime | Days the asset sits idle and earns nothing |
| Exit cost | Time and commission to sell the asset later |
The lease side has hidden items too: annual escalation, the deposit's opportunity cost, relocation at the end of the term, and the risk of non-renewal in a location your customers know. For a shop with local footfall, that last risk often outweighs every number in the spreadsheet.
A step-by-step framework
- Set the decision horizon — the shorter of the asset's useful life and the period you genuinely need it.
- Map the purchase cash flows year by year: down payment, instalments, maintenance, insurance, and residual value in the final year as an inflow.
- Map the lease cash flows year by year, with a realistic escalation rate and the deposit returned at the end.
- Calculate each option's tax saving: depreciation times the tax rate for purchase, rent times the tax rate for leasing.
- Discount both streams to today at a rate at least equal to your true cost of funds.
- Compare the totals as a percentage of overall cost, not in absolute terms.
- Run a sensitivity test. Does the answer flip if rent escalates faster, or the machine fails two years early?
If the gap is under roughly ten per cent, treat the options as equivalent and decide on flexibility and risk instead.
Before running any numbers, check the utilisation rate. An asset used less than half the available time is almost always cheaper to lease, whatever the spreadsheet says.
Depreciation versus rent expense
The tax difference between the two options is a difference in timing, not in total deduction.
Under purchase, the cost is not expensed at once. Article 149 of the Direct Taxes Act and the statutory schedule spread it over the useful life, so the tax shield is slow. Under an operating lease, rent reduces taxable profit in the year it is incurred, provided the usual conditions for deductible expenses are met: a registered lease or one with a tracking code, payment from the company bank account, a clear business purpose, and withholding of rental tax when paying an individual landlord. Cash rent under an unregistered agreement is the most reliable way to have an expense disallowed.
On the purchase side, keep an official invoice, an entry in the fixed asset register, and depreciation running from the date of first use.
Do not record a lease-to-own contract as an operating lease. Once the risks and rewards of ownership have transferred, the leasing standard requires finance lease treatment: asset and liability on the balance sheet, each instalment split between principal and finance cost. Getting this wrong distorts the statements and invites challenge during assessment.
The inflation argument, properly framed
"Buy property, it will appreciate" is usually true over the long run, but it carries two conditions. Appreciation is not cash until you sell: you become wealthier on the balance sheet while the bank account stays where it was. And capital locked in an asset has left the operating cycle — if your operating margin is strong, the return on that cash inside inventory and sales may well exceed property appreciation. That trade-off is the core of working capital management.
Three options at a glance
| Criterion | Cash purchase | Financed purchase | Lease |
|---|---|---|---|
| Pressure on initial liquidity | High | Medium | Low |
| Long-run total cost | Usually lowest | Medium to high | Medium to high |
| Flexibility to change course | Low | Low | High |
| Balance sheet effect | Asset increases | Asset and liability increase | Off balance sheet if operating |
| Tax shield | Gradual, via depreciation | Depreciation plus finance cost | Immediate, via rent |
| Obsolescence risk | Buyer | Buyer | Usually the lessor |
When the answer is nearly obvious
Lean towards buying when the need is permanent, the asset is core to operations, utilisation is high, liquidity stays comfortable afterwards, and comparable premises are hard to find. Lean towards leasing when the need is seasonal or project-based, the technology is changing, the business is still testing its market, or working capital is tight.
Two recurring errors: ignoring opportunity cost on the down payment, and optimism about residual value — specialised second-hand machinery sells for far less than owners expect. Before adding a fixed cost, run the break-even analysis.
If you would like to run this calculation on your own numbers, a short session is usually enough.
Key takeaways
- Loan instalments and rent are not comparable figures; compare total cost over a defined horizon.
- Include opportunity cost, maintenance and residual value, and test the result for sensitivity.
- The tax difference is mainly one of timing, not total deduction.
- Lease-to-own contracts are finance leases, not operating leases.
- Inflation supports the case for buying but never replaces a liquidity analysis.
