8 realistic ways to make extra money (and which ones to avoid)

There's a limit to how much you can cut back; there's far less of a limit on how much you can earn. But the internet is full of easy-money promises that end up costing you. These are realistic options, from the quickest to the more involved.

Quick wins

• Sell what you don't use. Clothes, electronics, furniture, books or toys on second-hand marketplaces. It's money you already have, just tied up.
• One-off jobs. Furniture assembly, helping people move, pet sitting, dog walking or house sitting. Paid per job and easy to fit into weekends.
• Seasonal and event work. Holiday retail, summer hospitality, conference and event staff. Often well paid per hour for short periods.

Get paid for what you know

• Tutoring. Languages, maths, music, exam preparation or tech help for older people.
• Freelancing. Design, writing, translation, video editing, coding or social media for small businesses. Start with people you know and ask for reviews.
• Services for small businesses. Many shops and sole traders need help with their website, photos or basic bookkeeping and don't know who to ask.

Medium-term options

• Rent out what you own. A parking space, storage room or equipment such as tools or camera gear.
• Create a digital product. Templates, courses or guides about something you know well. It takes upfront work and sales aren't guaranteed, but it scales better than selling hours.

Red flags

• You have to pay to start working or buy a "starter kit".
• Your income depends on recruiting other people (pyramid schemes).
• High, guaranteed returns from trading or crypto.
• Requests for your bank details or to pass on money for someone else.

Don't forget tax

Extra income may need to be declared, and regular side income may mean registering as self-employed. Check the rules where you live before you start, so a good idea doesn't end in a fine.

Make the extra count

The risk with side income is that it quietly disappears into everyday spending. Decide where it goes before it arrives: your emergency fund, a debt or a specific goal. In MonVault you can log each extra income by source and see how much it really adds to your goals.
