Savings Calculator

Updated 5 April 2026​
When you transfer money into a savings account, the interest you earn builds up over time. Our savings calculator helps you see and understand how your money can grow, and how much you can save up over time.

Savings calculator tips

  1. First, run the numbers without a monthly deposit. Then, re-calculate again with $20, $50 or $100 monthly contribution. You will see that regularly adding even the smallest amount can speed up your savings plan. 
  2. If you're unsure of the interest rate to use, 4% to 6% p.a. can be found right now from most banks and credit union investment accounts. 
What Happens When You Actually Track Where Your Money Goes?
  • We hear it constantly - MoneyHub readers who start using spending analytics find $100–$500+ in monthly waste they had no idea existed - forgotten subscriptions, bank fees, recurring charges that can easily be cancelled, the $10+ purchases that happen three times a week.
  • It's not that people spend recklessly – it's that they've never actually seen where the money goes.

This Is Why We're Big Fans of the Award-Winning Booster Savvy
  • Savvy solves two problems at once - your money earns 2.25% p.a. (reviewed monthly) while the built-in spending analytics show you exactly where it's going.
  • Traditional banks have no incentive to help you spend better – they profit from overdraft fees, credit card chaos, minimal interest, and your general disorganisation.
  • Savvy flips this. It's a transactional account with the returns of a savings account and the insights of a budgeting app – all in one place.

What makes Savvy worth considering:
  • Competitive Returns: Earn 2.25% p.a. on your entire balance - every cent earns a return from day one, calculated daily, paid monthly with no minimum balance required.
  • Instant Access, No Penalties: Withdraw anytime without sacrificing your return. This flexibility is rare for accounts paying meaningful returns.
  • No monthly account or card fees: Savvy is focused on making sure you earn returns.
  • Stacks: Divide your money into multiple purpose-built accounts – bills, savings goals, emergency fund – each earning the same rate. Automate your financial organisation.
  • Spending Insights: Real-time analytics show exactly where your money goes. We believe this is essential for anyone wanting to build better habits.
  • Automation Tools: Boost rounds up purchases and saves the difference. Sweep captures excess funds. Salary Split divides your pay before you can spend it. These are small actions that compound.
  • Full Transactional Functionality: Mastercard debit card (physical and digital), Apple Pay, Google Pay, automatic payments, and the ability to receive your salary directly.
  • Tax Efficiency: Structured as a PIE, taxed at your PIR (capped at 28%) – often more favourable than standard savings account tax treatment.

Know This: Booster is not a bank. Savvy is an investment in the Booster Savvy Fund, a cash-based managed fund. This means different protections apply compared to bank deposits – understand the distinction before opening an account.

Our View: Savvy works best for people who want their money to earn meaningful interest while maintaining full flexibility, and who value the behavioural tools that help build better financial habits. The spending insights alone help many users identify and eliminate wasteful expenses.
