0% Finance Costs Explained: Unlock Maximum Sales Without Breaking the Bank

Ever wondered how those irresistible 0% finance deals actually work?

They're a staple in UK retail – from furniture and fitness equipment to dental treatments and vocational courses – and they've been driving sales for decades.

Let's break it down, so you can maximise the commercial upside while keeping costs in check.

The Basics: It's Not Magic Money

Your customer pays 0% interest over the term.

But lenders don't work for free – the cost is covered by you via a merchant subsidy.

This is a percentage of the loan amount, deducted before you receive settlement.

Subsidy scales with the interest-free period. Here's an example: 

  • 12 months 0% = ~7.9% subsidy
  • 24 months 0% = ~11.7% subsidy

Example: Bicycle Retailer

On a £2,000 bike sale with 24 months 0%: 

Customer pays £83.33/month (interest-free). 

You, the merchant, receive £1,766 after the 11.7% subsidy (£234 deducted).

Why Bother? Proven Sales Rocket Fuel

Retailers love 0% because it delivers measurable ROI:

  1. Boosts marketing response – Prominent 0% messaging drive more enquiries, website traffic, and footfall.
  2. Lifts conversion rates – Turns browsers into buyers by making purchases affordable.

Result? Higher average order values and more deals closed – especially for medium-to-high value goods like jewellery, motorbikes, bathrooms, or solar and heatpumps.

Other Alternatives: Part-Subsidised Options

Not ready for full subsidy? Go hybrid!

Products like 9.9% APR split the interest:

  • Customer pays a low rate (beats most credit cards).
  • You pay a smaller subsidy (e.g., 3-5%).

This helps keep offers attractive while reducing your costs.

Key Factors to Nail Your Strategy

FCA authorisation unlocks the best rates and full product range.

Benchmark competitors: Match or beat their terms to stay ahead.

Control costs with proven tactics: Tiered offers, minimum order thresholds, seasonal promotions, or blending 0% with interest-bearing.
