I’ve been working on a free calculator for people in New Zealand who want to quickly estimate their take-home pay from their salary.
It can be useful for checking things like:
Gross salary → estimated take-home pay
PAYE deductions
KiwiSaver contributions
Student loan deductions
Weekly, fortnightly and monthly pay
Hourly rate → annual salary
I’ve made it available here:
Would be interested in feedback from NZ users — particularly if there are any salary/PAYE calculations or features you think should be added

Looks remarkably similar to https://www.paye.net.nz/calculator/ , are there different features planned on the roadmap?
