Applying to positions to get an idea of salary offers

Hello. I've been with my current company for a year now, and I want to explore other opportunities to see if I can find one that has a better offer to what I am getting now. I'm okay naman with the culture of my current company and I love the people I work with, kaso harmonious relationships with co-workers can't pay the bills, and with the current rate ng inflation, wala na akong savings kasi ang liit talaga ng pasahod. Huhu

What would be a good reason to tell the recruiter the reason why I am looking for qnother opportunity?
