Installment Calculator for PrestaShop — Show Financing Options on the Product Page

Written on . Posted in Modules.

The Installment Calculator module for PrestaShop automatically displays installment options on every product page, with dynamic calculation based on the current product price and available financing plans. Customers see immediately how much they will pay per month — without having to navigate away or contact the merchant.

Why Does the Installment Calculator Increase Sales?

High-ticket products often face high cart abandonment rates because customers hesitate to commit to a large one-time payment. Showing "only €29/month" dramatically changes the perception of cost and reduces hesitation. The Installment Calculator does exactly that: it converts a high price into manageable monthly payments, boosting conversion rates especially in categories such as electronics, home appliances and furniture.

Key Features

  • Dynamic installment calculation: Automatically displays the monthly installment based on the current product price, including any active discounts.
  • Multiple financing methods: Support for different plans (3, 6, 12, 24 installments) with configurable interest rate per plan.
  • Customizable installment range: Set minimum and maximum product price thresholds to activate the calculator.
  • Display on product page: Embedded directly below the price with a clean UI that fits any store theme.
  • Calculation with or without down payment: Option to define a down payment percentage with automatic calculation of the remaining amount.
  • Compatible with Greek banks: Pre-configured plans for major Greek banks and card issuers.
  • Responsive display: Full mobile and tablet support — installment options render correctly on every device.

Benefits for Merchants

Offering installment options is not just a feature — it is a sales tool. Merchants who display installment options alongside the price consistently record significant increases in Average Order Value (AOV) and reductions in cart abandonment. For high average-price categories, the Installment Calculator acts as a silent salesperson, convincing the customer that the purchase is affordable.
