New comparison rate calculator for Police Bank to internally calculate their comparison rates

Police Bank came to GBST with one key objective: to make it more efficient to produce comparison rates for their loan products.

Police Bank were operating with manual processes to produce comparison rates, which was not sustainable long term, due to the changing nature of interest rates.

GBST and Police Bank partnered to build a comparison rate calculator. This project was completed in four phases: build of calculator prototype, actuary sign off, build of calculation engine and build of user interface.

The outcome? Police Bank and their internal staff can access a compliant and modern tool that can quickly generate the comparison rate for their loan products.

Home loan calculators using natural language inputs to engage

Kiwibank partnered with GBST to build five home loan calculators, using its Equate technology platform with user experience and design created by Wellington based digital design agency DNA.

The key difference with these calculators is the use of natural language inputs. Kiwibank recognised their calculators were one of the most popular pages on their website but research showed that people were getting overwhelmed on the home loan journey and not knowing where to start.

The calculators walk first home buyers through the home loan process and introduce concepts people may not be familiar with. They’re a great place to start and complement Kiwibank’s customer service.

Insurance Fees Calculator

We were approached by the Wealth Management division of ANZ Australia to develop a calculator illustrating how insurance fees would be changing for members from the 1st of July 2020. They required a calculator to be in production on their servers by April to meet regulatory requirements.

In just a week we had: developed a spreadsheet prototype for the calculator, built the UI and calculation engine for the tool, developed a UI design for the display of results, set up automated testing between the tool and spreadsheet to validate results, performed internal QA, transformed and imported the client-supplied data, and provided the client with their UAT environment. All whilst still adjusting to our new working from home arrangements due to COVID-19.

NAB EL Advisors increase customer engagement through client portfolio modelling

We partnered with NAB Equity Lending to build a ‘What If’ modelling tool which provides useful illustrations for NAB Equity Lending advisors and clients to model client portfolio options.

Designing a tool that can compare complex scenarios seamlessly through a user-friendly interface, that can be used with customers face to face and in remote co-browsing sessions, is how you increase client engagement and bring to life the effect certain decisions have on a future financial position.

Advisors can discuss future financial positions with their clients in-person or build the new portfolio and download and save it as a pdf. There is also a public version of the ‘What If’ tool so engagement can be two ways between client and advisor.

In addition, the tool can show prospective clients their future position if they were a NAB Equity Lending client to increase leads and convert new clients.
