How the CAPEX to OPEX calculator works

Enter your vendor cost and margin

Enter the principal / vendor cost and your reseller gross margin (% of selling price). The CAPEX selling price is computed automatically as cost ÷ (1 − margin%). Leave margin at 0% if your figure is already the final price.

Set the tenure and interest rate

Choose the financing term (1–5 years, or switch to months) and the annual interest rate the financier or partner offers. A higher rate or longer term lowers each payment but raises the total paid.

Pick payment timing and any residual

Arrears charges at the end of each period (most common); advance charges at the start. Add a residual / balloon value if a lump sum is due at the end rather than amortizing to zero.

Read the monthly figure and break-even

The headline shows the monthly OPEX payment, the total over the tenure, and the financing cost. The buy-vs-finance block shows when financing overtakes the cash price, both nominally and in present-value terms.

How the CAPEX to OPEX calculator works

This calculator takes your vendor cost and reseller gross margin, derives the one-time CAPEX selling price (cost ÷ (1 − margin%)), and converts it into an equivalent monthly payment plan (OPEX) — so you can compare paying upfront against spreading the cost over a financing term. Leave margin at 0% if the amount you enter is already the final price. Everything is computed instantly in your browser — no figures are sent to a server or stored.

The monthly figure is a standard loan-style amortization of the purchase price, using the same fixed-payment (PMT) formula banks and leasing companies use. Each monthly payment is identical, the financed balance reduces a little each month, and the sum of all payments is greater than the upfront price. That difference is the financing cost.

The annual interest rate reflects the cost and risk of financing — broadly the prevailing benchmark rate plus a margin for credit risk and term. The calculator also shows the effective annual rate, which accounts for monthly compounding (it reflects compounding only and excludes any fees).

Beyond the monthly figure, the buy-vs-finance block answers the question buyers actually ask: does spreading the cost help or hurt? The nominal break-even is the point where cumulative payments overtake the cash price. The present-value comparison discounts the future payments at your cost of capital — because a dollar paid in three years is worth less than a dollar today, financing can be competitive even though the nominal total is higher.

For sellers and resellers, the optional (collapsed) economics panel separates the product gross margin from any financing income, and — only when you self-finance the deal (a captive lease) — estimates the internal rate of return and net present value on the cash you deploy. If a third-party financier funds the asset, you are paid the purchase price upfront and earn the product margin only; the financing income belongs to the financier.

A note on tax: this tool models cash flows only. In practice OPEX is typically expensed while CAPEX is depreciated, and that accounting difference can change the real after-tax cost in either direction. Treat the figures as pre-tax planning estimates.

10 Facts About CAPEX & OPEX Financing

01

CAPEX is a one-time capital outlay; OPEX spreads the same value into recurring operating payments.

02

The monthly payment uses the same PMT amortization formula banks and leasing companies use worldwide.

03

Margin-on-selling-price means a 30% margin is 30% of the final price — not 30% added to cost.

04

A longer tenure lowers each payment but always increases the total financing cost.

05

The effective annual rate is higher than the nominal rate because interest compounds monthly.

06

In an amortizing schedule, early payments are mostly interest; later payments are mostly principal.

07

Discounting future payments at your cost of capital can make financing competitive despite a higher nominal total.

08

A residual (balloon) value lowers the monthly payment but leaves a lump sum due at the end of the term.

09

In a captive lease the reseller earns both product margin and financing income; with a third-party financier, margin only.

Frequently Asked Questions

  • No. It is an indicative model that estimates a monthly figure from the inputs you provide. A formal lease or loan quotation depends on a credit assessment, the financier's actual rates, and any fees or taxes, and may differ.
  • A longer term lowers each monthly payment but increases the total amount paid, because interest accrues over more periods. Use the tenure field to compare.
  • Use the rate your financier or partner actually offers, or a realistic market estimate. As a rough guide, business IT financing rates commonly fall in a single-digit to low-double-digit annual range, depending on credit profile and term.
  • No. The figures exclude GST/VAT, stamp duties, arrangement or processing fees, insurance, and any other charges unless you build them into the purchase price. Add them separately for a complete picture.
  • CAPEX (capital expenditure) is a one-time purchase that is typically capitalised and depreciated. OPEX (operating expenditure) is a recurring cost that is typically expensed in the period incurred. This tool converts a CAPEX price into an equivalent OPEX payment stream so you can compare them.
  • It expresses margin as a percentage of the final selling price rather than of cost. Selling price = cost ÷ (1 − margin%). A cost of 49,000 at a 30% margin gives 49,000 ÷ 0.70 = 70,000. This differs from a 30% mark-up on cost, which would give only 63,700.
  • It is only shown for a captive lease, where the reseller funds the asset and collects the payments. The IRR is the annualised return on the cash actually deployed (your vendor cost), given the monthly receipts. If a third-party financier funds the deal instead, you are paid upfront and there is no financing IRR for you — only the product margin.
  • Because money has a time value. A payment due in three years, discounted at your cost of capital, is worth less than the same amount today. The present-value comparison applies that discount to the monthly stream, so financing can be competitive with cash even though its nominal total is higher. The nominal break-even ignores this; the present-value figure does not.
  • Yes. Enter a residual / balloon value and the schedule amortizes down to that figure instead of to zero, leaving a lump sum due at the end of the term. The residual must be less than the purchase price.
  • No. All calculations run locally in your browser. Your inputs are not transmitted or stored. Your figures can be shared only if you copy the page URL, which encodes the inputs for your own convenience.

Important — please read.

For information and planning purposes only. This calculator provides indicative estimates based solely on the figures you enter. It is not financial, investment, tax, accounting, or legal advice, and not an offer, recommendation, solicitation, or quotation for any financing, leasing, hire-purchase, credit, or product.

Estimates, not guaranteed figures. Results are mathematical illustrations using a fixed-rate amortization model. They assume a constant interest rate and equal payments, and they exclude GST/VAT, stamp duties, arrangement, processing or administrative fees, insurance, early-settlement charges, and any other costs unless you include them in your inputs. Actual figures will differ.

Actual terms vary. Real financing, hire-purchase, or leasing terms depend on the provider's prevailing rates, a credit assessment of the customer, the specific agreement, and prevailing market conditions. Reseller margin, financing income, IRR, and NPV figures are illustrative business estimates only and do not represent assured returns.

No reliance; seek professional advice. Do not make purchasing, financing, pricing, tax, or investment decisions in reliance on this tool alone. Obtain independent advice from a qualified financial, tax, legal, or accounting professional, and a formal written quotation from your financier, before committing.
