This isn’t a mandatory yardstick but based on personal scale of reasoning.
Open a bank account: This may sound so awkward but it’s a great start in spending wisely. You’re prone to spending lavishly when going about with cash. (Go cashless)
Bulk-shop (mostly non-perishables) provided your capable. This helps save money as there’s no assurance of fixed prices of items in this dispensation.
Research good investment schemes. Invest based on your capability. Little drops of water makes an ocean.
Review your bank statement. This could be done monthly or quarterly. It’s helps to keep you in check.
Drink water. It’s beneficial for your health. (Stay hydrated)
Don’t go about making purchases based on impulse.
Don’t over-borrow. This would help to avoid overwhelming debts. (Limits)
Regulate your monthly eat out.
Endeavour to pay your bills on time to avoid penalties.
Walk, go on bicycles, ride a bike or use the public transportation instead of having a car or moving about in taxi.
Shop where students are given discounts.
Check out books from the library instead of buying books needed for a short period.
Go for lectures. Failure to attend lectures you’re paying for is like throwing money out the window.
Never sign up for a loan that’s unrelated to your education.
Shopping outfits during off-seasons is cost-effective (for instance, you may consider shopping summer wears prior to winter because many vendors are bound to do clearance sales).
Sell your used items rather than leave them to waste away provided they are still in good conditions.
Avoid buying name brand items. Go for the regular ones if need be. They’re exactly same at a highly pocket-friendly price.
