Find coupon codes to save money
Before you purchase something online, spend some time to look for online coupon/promo codes. Often, companies would promote discounts/vouchers on their own social media channel (e.g. Facebook/Instagram), as well as on their website or other e-commerce websites or apps. So, make sure you do your research online before hitting that checkout button!
Prepare a weekly budget
Plan your entire week's spending ahead. Set aside just that amount, and a small sum as reward. Then, keep the rest in a high-interest savings account. Try your best to stick to your plan, and if you do, reward yourself on the weekend with the small reward amount you set aside.
50/30/20 Budgeting rule
A general rule of thumb on creating a budget is the 50/30/20 rule: 50% on needs, 30% on wants, and 20% for savings/long term investment. Of course, you are free to decide a different combination whether it's 60/20/20, or 40/40/20. Just make sure you have a decent proportion (i.e. 20% or more) on savings!
Hide your credit cards safe in the house to curb spending
Having trouble staying disciplined and not overspend on your credit card? One trick you can implement is to make your credit card difficult to access. For example, keeping your credit card in a safe, tucked inside your luggage bag on top of your wardrobe, or "freezing it" in the freezer so that you need to wait 30 minutes before you can use your card. The point is, to make it an inconvenience to spend, and perhaps that would stop you from that impulse purchase!
Prioritise high interest rate to low interest rate when liquidating assets
If you ever need to incur interest or penalty due to cash flow needs -- whether it's breaking a fixed deposit, or tapping into cash advance on your credit card or overdraft on your current account, make sure you prioritise your decision based on the interest rate.
