There is no right answer regarding how much you should spend on an engagement ring. It primarily depends on your financial situation and what you feel comfortable spending. However, if you are looking for a guideline, it is generally recommended that you spend two to three months' salary on the ring. This ensures that you are getting a quality ring without putting yourself into debt. Of course, ultimately, the decision is up to you and your partner.
If you have your heart set on a particular ring that is outside your budget. You can save up for the ring over time, finance it through a jewelry store, or look for a similar style that is more affordable. No matter what route you choose, remember that the most important thing is that you are committing to your partner and not just buying them a piece of jewelry.
