The basics

So… what actually is a sinking fund?

A sinking fund is money you set aside a little at a time for a specific expense you already know is coming — a holiday, car rego, insurance, Christmas, a new laptop. Instead of getting blindsided when a big bill lands and reaching for a credit card, you've quietly been filling that pot for weeks or months. So when the bill arrives, the money's already there.

Without one

A $1,200 car rego bill lands out of nowhere. You scramble — dip into savings, or put it on a card and pay it off with interest.

With a sinking fund

You quietly set aside $100 a month across the year. When the $1,200 bill lands, it's already covered — no stress, no debt.

How it works

Three steps to saving with purpose

01

Create a fund

Name it, set a goal amount, and pick a target date. Travel, tech, emergencies — one dedicated fund per goal keeps your money intentional and your mind clear.

02

Log deposits

Every time you save, record it. SinkWise shows your real-time progress and tells you exactly how much you need per day, week, or month to stay on track.

03

Hit your goal

Watch the progress ring fill. Premium users get AI Insights that flag if you're falling behind — with health scores, risk analysis, and forecasts — before it's ever too late.

Why Premium

Premium pays for itself the first time it catches one of these.

✦ Premium

Spots a cash crunch before it happens

You're saving for a $3,200 trip in March — but your $940 car rego lands the same fortnight. AI Insights sees the clash coming and tells you to top up the rego fund now, before it bites.

✦ Premium

No more debits that ambush you

Phone plan, car insurance, gym, streaming — the Bill Tracker lays out exactly what's leaving your account this week, so the $214 insurance debit never catches you with $190 in the bank.

✦ Premium

Shows where the money actually goes

The Expenses Tracker reveals your subscriptions quietly add up to $96 a month. See your true cost of living by category — and know exactly what's left over to save.

✦ Premium

Turns "what if" into a real date

The What-If Calculator shows that an extra $40 a week gets your house-deposit fund done seven months sooner. See the trade-off, then decide if it's worth it.

✦ Premium

Warns you before you dip into the red

The Cashflow Forecast projects your combined balance across every fund — so you know it'll dip to $380 in late March before a payment bounces, not after.

✦ Premium

Puts your next dollar where it counts

Got $200 spare? Instead of splitting it evenly, SinkWise says put $150 on the rego due in three weeks and $50 on the holiday — so your money always works hardest where it matters most.

Premium

This isn't just more features.
It's a completely different level.

Premium gives you the tools serious savers use — AI analysis, expense tracking, forecasts, and enough fund slots to organise every corner of your financial life.

FAQ

Questions, answered

What is a sinking fund?
A sinking fund is money you set aside over time for a specific planned expense — a holiday, a car repair, a new laptop. Instead of scrambling when the bill arrives, you've already saved for it.
What's the difference between 10 and 80 funds?
Free users can create up to 10 sinking funds — plenty to get started. Premium unlocks up to 80, giving you the room to track every goal, whether that's a holiday, car service, Christmas, dentist, annual subscriptions, and everything in between.
How does the AI Insights feature work?
AI Insights uses your fund balances, goals, target dates, and deposit history to generate a Savings Health Score (0–100), Smart Alerts, risk analysis, cashflow forecasts, and a plain-language summary. The AI is powered by Anthropic. Your data is used only to generate your personal analysis — we never use it to train any AI model.
What does the Expenses Tracker do?
The Expenses Tracker (Premium) lets you log recurring expenses — Netflix, water bills, gym memberships, phone plans — with a frequency (monthly, fortnightly, etc.) and category. It shows your total cost of living per period so you can see exactly what's left to save.
Can I cancel my Premium subscription?
Yes — cancel any time from inside the app with one click. You keep Premium access until the end of your current billing period. No lock-in, no questions asked.
Is my data safe?
Your data is stored securely in Google Firebase with per-user isolation enforced by Firestore security rules. We don't sell your data and we don't use it for advertising. Full details in our Privacy Policy.
