Quick Interest Slider

75 Quality Score

Active Installs

14/30

With about 1,000 active installs the plugin has a modest but real user base, and the score is capped because it is not a widely adopted tool in the WordPress lending niche.

Update Freshness

25/25

The plugin was updated on May 21, 2026, which is excellent and shows the author is actively maintaining the codebase against current WordPress releases.

User Rating

14/15

A 92 out of 100 across 13 ratings is very strong, though the small sample size means the average is more directional than statistically conclusive.

Support Health

8/15

There are zero support threads on the WordPress.org forum, which is a yellow flag since it leaves no public track record of how the author handles bug reports or user questions.

WP Compatibility

15/15

The plugin is tested up to WordPress 7.0 and requires WordPress 6.0, so it is fully aligned with current core versions and will install cleanly on modern sites.

What It Does

Quick Interest Slider is a lightweight WordPress plugin that adds a repayment calculator to your site, letting visitors drag two sliders to pick a loan amount and term while viewing calculated results in real time. It is designed to be dropped into a page or post via a shortcode and requires no configuration beyond styling preferences. The interface is jQuery based and intentionally minimal.

Who It's For

This plugin is well suited to small lenders, mortgage brokers, credit unions, and real estate or auto loan sites that want a quick, interactive quote tool without building one from scratch. It also works for financial advisor blogs or comparison pages that need a simple monthly payment estimator embedded directly in content. If your business is built around letting prospects play with numbers before contacting you, this fits.

Who Should Skip It

Skip it if you run a high volume lending platform that needs APR, amortization tables, currency switching, or compliance disclosures baked in, because this tool only outputs a range of figures. You should also pass if you need a calculator that saves leads to a CRM or integrates with a loan origination system, since the plugin does not appear to handle either.

The Bottom Line

Quick Interest Slider is a tidy, well maintained, and well rated little calculator that does one job and does it without bloat, making it a smart pick for small financial sites that just need a slider based payment estimator. The lack of public support threads and the absence of any comparable alternatives in our index mean you should test it on a staging site first and confirm the calculation logic matches your lending rules. For most personal finance and small brokerage sites it is a solid, low risk choice.
