Those of you in your 30s know it's the decade when a lot of significant things happen.

At work, you're probably building on the momentum you started in your 20s with your eye on snagging promotions and working towards the career highs and rewards that come later. Away from work, you're likely doing a bunch of other things, too — like home purchase, starting a family, travel, etc.

Along the way, there are some smart money moves you can make now that "Future You" will seriously thank you for.

Build a foundation

If you have high-interest debt, or if you don't have an emergency fund saved up yet, get these basics set up first.

We recommend using the 50/30/20 rule as an easy-to-use budgeting approach to help you get there.

First things first: It's not actually a rule that must never be broken. Instead, it's a guideline — or, if you're dealing with debt, a general direction. With this approach, you're trying to allocate your take-home pay into three buckets:

Fifty per cent goes to needs. This includes bills, groceries, transportation, housing, minimum debt payments, work clothes, and other essential items.

Thirty per cent goes to wants. Eating out, happy hour, shopping, Netflix accounts, or trips to Bali … fun's important.

Twenty per cent goes to Future You. Three things in this bucket: debt payments above the minimums, saving, and investing.

Step one is pay down debt. For any debt with a repayment interest rate above 5 per cent, eg, credit card debt, personal loans, it's going to cost a lot in interest to hang on to that balance.

Pay the minimums across all your accounts and put any extra cash you can find in your budget toward the balance with the highest interest rate. This technique will help you pay the least amount of interest possible.

Next up is Emergency Fund. Sometimes it rains, and sometimes it pours. And sometimes it totally floods.

We recommend saving three to six months' worth of take-home pay, depending on how stable your income is. For example, if you're a single freelancer, you might want to do six months' worth.

That will give you more of a cushion to fall back on since your income might be irregular. On the other end of the spectrum, if you've been working fulltime for years and have another member of your household who helps pay the bills, then three months' worth might be enough.

Either way, keep your emergency fund in cash (ie. a savings or checking account, not dollars under the mattress) so that you can get to it when you need it.

Get on track for retirement or first home

If you're still establishing a solid financial base, keep doing what you're doing. But no matter what, try to take full advantage of KiwiSaver.

The Government will contribute 50 cents for each dollar you contribute in a financial year, up to a maximum of $521.43, and, if employed, your employer should contribute at least 3 per cent of your gross wages. That's effectively free money.

Once you've got debt and your emergency fund checked off the list, you can turn your attention more fully to your retirement or get ready for home ownership (if that's your goal). The sooner you can, the better — a dollar invested "today" can be worth more than a dollar down the line (The power of Compound Interest).

If possible, consider increasing your KiwiSaver contributions to 4 per cent or 8 per cent of your gross salary (further options of 6 per cent and 10 oer cent likely to be introduced in 2019) to stay on track to achieve your goals.

Let your priorities guide the way.

Debt, savings, retirement, home ownership, kids … you might be juggling a lot of priorities. But those aren't the only goals that investing could potentially help you check off.

Perhaps you always dreamed of starting your own business or taking a big 40th birthday trip to Rome. Or maybe you just want to build wealth. Slot those goals in with your other priorities and start carefully investing as much as you can to make them happen.
