PayDay vs savings apps FAQs
The questions Kiwis ask most when deciding between the two.
Do round-up apps or PayDay save you more?
On the worked example on this page, PayDay saves about nine times more. A round-up app collecting an average 50 cents across roughly 100 transactions a month puts away about $50 a month, or around $600 a year. A 10 percent PayDay split on an average New Zealand salary of $4,500 a month after tax puts away $450 a month, or $5,400 a year.
What is the difference between round-up saving and pay splitting?
A round-up app saves the spare change on each purchase after you spend, so what you save depends on how often you tap your card. PayDay splits your pay the moment it lands, before you spend anything, by a percentage or fixed amount you set once.
Are round-up savings apps worth using in New Zealand?
They are good at what they are built for. Round-up apps work best for building a savings habit if you are starting small, for accumulating fun money for treats or small purchases, and as supplemental savings alongside something larger. They are not designed to fund a house deposit or an emergency fund on their own.
Which is better for a house deposit or emergency fund?
PayDay. It works best for serious savings goals such as a house deposit, an emergency fund or investment capital, for automating bills and savings together, for variable income where a percentage means you always save proportionally, and for splitting across accounts at any New Zealand bank.
Can I use PayDay and a round-up app together?
Yes, and plenty of people do. PayDay handles the heavy lifting by moving 10 to 20 percent of your income to savings, bills and investments the moment your pay lands, and a round-up app quietly collects the spare change on top of that.
Ready to save seriously?
Stop collecting spare change. Start splitting your pay automatically. PayDay is free to join the waitlist.
