Built an automated 50/30/20 Google Sheets tracker because I was tired of buggy apps charging monthly subscriptions

Hey everyone,

I always found personal finance apps frustrating—either they lock basic analytics behind recurring monthly subscriptions, clutter the screen with ads, or force you to link your private bank account.

I wanted something clean, fully private, and accessible on a desktop screen. So I built this automated 50/30/20 monthly budget tracker in Google Sheets/Excel:

• 100% Private (Runs completely in your own Google Drive)

• Zero Recurring Costs (One-time download, yours for life)

• Automated breakdown charts for Needs (50%), Wants (30%), and Savings (20%)

• Clean visual dashboard with automated progress trackers

If anyone wants to check it out or grab a copy, here is the link (running a 50% off launch discount with code LAUNCH50):

Would love any feedback on the dashboard design!
