Booster’s Investor Offerings
What is Booster Savvy?
Booster Savvy is a digital and physical debit card and app based smart account offering by the investment manager Booster that merges everyday transactional capabilities with an investment fund. Traditional banks often do not offer interest on transactional accounts. Savvy however offers an attractive rate of return.
Why would I use Booster Savvy over other credit or debit card providers?
Why would I use Booster Savvy over other credit or debit card providers?
- Our view is simple - the biggest benefit of using Booster Savvy over the providers is the deep analytics and insights platform that the app offers (which we detail below). This is by far one of the most advanced budgeting and analytics financial apps in the New Zealand market.
- Further, it's one of the only financial offerings fully integrated with a debit card (so your spending, savings and budgeting can be done all in one app/place).
Understanding the Features of the Booster Savvy App
Booster Savvy, available on the Booster NZ app has several features and functionality to help investors save, analyse their spending and make better decisions. We outline each feature below:
1. Booster NZ’s Net Worth Tracking (Assets/Liabilities)
Booster's wealth tracking is simple and easily laid out, allowing you to get a helicopter view of all your assets and liabilities. Whether it's your term deposit with a bank, the equity in your property or your mortgage associated with that, you can add and integrate all your financials to show your net worth.
The screenshots below illustrate what this app functionality looks like:

2. Booster Savvy’s Cash Flow and Forecast Analysis
- In contrast to other banking apps that just show the deposits and withdrawals, Booster Savvy analyses and learns to predict your expected expenses and bills, letting you know how much you have to spend and how long until your next payday.
- This functionality can be incredibly useful when planning interim cash flow before your next payday (and whether or not you can afford that discretionary purchase or extra morning coffee).
- Booster Savvy also shows the cash flow in and out of your accounts, providing snapshot views of your spending habits on a monthly, weekly, and daily basis.

3. Booster Savvy’s Stacks and Insights
- Booster Savvy’s Stacks functionality allows you to easily create accounts (known as Stacks) to separate various expenses and savings funds, and set specific individualised targets for each discretionary area.
- These stacks are customised to each user, so whether you're looking to save for a new set of skis, or are saving up for a house deposit, stacks ensure you've got a line of sight to your savings targets and are focused on your savings goals.
- Booster Savvy also has its own tab for Insights and analytics drawn from your spending patterns and assets/liabilities.

4. Boost, Sweep and Salary Split Features
Booster Savvy has additional functionality to help you continue saving toward your goals, all of which can be easily turned on and managed in the app:
Boost
Sweep
Salary Split
Booster Savvy’s Card and Transfer
Boost
- Boost helps to grow savings while you spend. The boost functionality works by rounding up expenses and allocating that small portion to your Stack of choice.
- For example, if you spend $4.50, Boost will round it up to $5.00. The extra 50 cents will go directly into your selected stack. You won't notice an extra 50 cents here or there, but these minor increments accumulate over time and help accelerate your savings journey. You can round up to the nearest 50 cents, $1 or $5.
- Additionally, Savvy displays your accumulated boosted savings daily, providing a sense of fulfilment from your savings regularly. The more seamlessly you can contribute to your savings goals, the easier it will be to reach them.
Sweep
- Sweep nudges you to transfer any leftover money into a specific savings stack before your next payday helping you to reach your savings target faster.
- Savvy will always get your approval before initiating a sweep (e.g. it won't move your money without your explicit permission). The more you sweep, the faster you'll reach your stack's saving target.
Salary Split
- Salary Split divides your funds before spending to reduce stress and anxiety around planning. If you're struggling with balancing your monthly expenses and savings, the Salary Split functionality can help you manage this. Salary Split automatically distributes and transfers money to your chosen Stack each payday, removing uncertainty and ensuring you don't overspend your paycheck as soon as it hits your account.
- Booster allows you to configure your Salary Split settings into the appropriate percentages. For example, 50% of your paycheck goes to your main spending stack, 30% to your stack for the travel fund to Europe, and 20% to your emergency fund stack.
- Rather than having to tediously track and manually transfer each amount into each savings account, Salary Split does this automatically, reducing the stress of managing your monthly paycheck. Knowing the amount you can spend on discretionary "enjoyment expenses" whilst leaving enough for your regular expenses is a huge benefit of the Salary Split function.
Booster Savvy’s Card and Transfer
- Booster Savvy supports Apple Pay (as outlined below) and Google Pay, enabling faster payments for anyone with tech-enabled devices (like smartphones or watches with payWave functionality). This can be especially useful if you don't have your wallet with you.

5. Returns Earned on Account Balances
Returns on Booster Savvy accrue daily and are paid aroundthe start of each month (which comes through as “Investment Returns” in the respective stack account - which can be seen below). Booster's 0.60% capped management fee is taken from the investment returns of the Savvy fund, not deducted from the return rate you receive. In addition there are no monthly account or card fees* and loads of free domestic transactions.
*Some transaction fees apply, including international transaction and FX fees. Merchants may apply surcharges which Savvy aren’t involved with.

A MoneyHub user gives candid comments on the functionality and features of Booster Savvy:
“The app seems to have lots of unique functions (like rounding up purchases, sweeping leftover money into savings buckets and splitting pay as soon as it hits your accounts) that apps like Revolut don’t have. These functions mean I can continue to save without really having to think about it or transfer any money - always a nice benefit.
Having said that, given the ability to link spending to one card and see all the analytics associated with budgeting and spending, I’ll definitely continue to spend on Booster Savvy (whilst earning a return on my money)” - I just won’t keep a whole lot of money in it.”

Booster Savvy vs Revolut
When comparing other debit cards integrated with budgeting capabilities, Revolut comes close to Booster Savvy, but we see it as less focused on saving and doesn’t pay returns on any balances. However, Revolut offers similar budgeting and spending analysis with the ability to set aside distinct accounts to save for discretionary expenses (like a trip to Europe). Further, like Booster Savvy, the app is seamless and easy to use.
A MoneyHub User comments about their experience with Savvy vs Revolut:
“Honestly, I was surprised that the app had so much functionality. Most New Zealand based apps either aren’t very functional (like ANZ or Westpac CashNAV) or aren’t New Zealand based (like Revolut).
The biggest thing I like about Savvy is the ability to set goals and see how you’re tracking towards them. Getting notifications when I’ve reached my savings goals is a really cool feature of the app (something that platforms like Revolut don’t really offer)".

Booster Savvy vs Bank Apps
Booster Savvy vs Westpac CashNAV
CashNAV is Westpac's budgeting app, linked exclusively to Westpac accounts. It aims to assist Westpac clients in better monitoring and controlling their expenditures. CashNav usually operates by connecting to the user's bank accounts, classifying transactions, and offering insights into expenditure patterns.
Key functionalities of CashNav typically include:
Key functionalities of CashNav typically include:
- Automated Transaction Classification: This feature sorts transactions into categories such as groceries, bills, and dining, simplifying expenditure tracking for users.

- Budget Management Tools: Enables the setting of budgets for various expenditure categories and monitors them in real time.

- However, as seen below, the app is arguably outdated and clunky - not offering high-resolution analytics and limited budget/forecast capabilities.

Booster Savvy vs ASB Spend Tracker
- The ASB mobile app now provides spend tracking, showing how your funds are allocated. There's no requirement for manual transaction categorisation - the spend tracker will automatically organise your expenditures into different categories (similar to Revolut above).
- By bucketing your spending into various categories (like general spending, dining out, account transfers, utilities, entertainment, etc.), you're able to monitor trends in your earnings and outgoings (and figure out whether you're saving enough or spending too much).
- You can reassign a single transaction or a group of similar transactions to a category that fits your preferences better.

​Booster Savvy vs BNZ App Spend Activity
Similar to other apps above, BNZ’s app also provides spend tracking, projections, forecasting and categorisations:
- Cash Flow Management: Gain a comprehensive understanding of your financial inflow and outflow and determine whether you're experiencing excess or deficit. Analyse your cash flow weekly or monthly, detailing the sources and uses of your funds. Set a weekly or monthly goal to improve your financial surplus.
- Monitor Your Expenditures: Keep track of your expenses across various accounts, identify your spending areas, and review your average expenditure on a daily, weekly, and monthly basis, including any fluctuations over time.
- Organise Your Expenditures: Your transactions will be automatically sorted into categories, but you can modify them, and the app will remember your preferences for future transactions. For example, you can reclassify your online streaming expenses under bills instead of entertainment simply by adjusting it in the app.
- Sort Your Expenses by Category: Use category filters to understand your spending habits and assist in budgeting. This feature lets you see how much you spend on things like utilities, groceries, dining out, or leisure activities.
- Assess Your Spending Categories: This feature allows you to compare up to five spending categories simultaneously. It helps you identify where you're spending the most or least or create comparisons to better understand your spending patterns and timing.
