The zero-based budgeting app that actually works in India

Zero-based budgeting comes down to one piece of arithmetic: income minus what you've assigned equals ₹0. That doesn't mean you spent it all by the end of the month. It means you decided where every rupee was going before the month even started.

Take a ₹45,000 salary as an example. ₹15,000 goes to rent, ₹6,000 to the EMI, another ₹5,000 for groceries. SIPs and savings take ₹8,000, transport and subscriptions ₹4,000. Whatever's left, ₹7,000, is what you've actually decided to spend on food delivery, going out, whatever you want that month. Add it up and it comes to ₹0. There's nowhere left for a rupee to hide.

By month-end you're not trying to reconstruct where the money went. You already know, because you decided it weeks earlier.

It holds up when the month isn't normal, too. A wedding invite, a festival, a sudden repair bill: give each one its own category, funded by a buffer you set aside on purpose. Otherwise you're quietly eating into your grocery money without noticing. And if a category does run dry early, you're the one choosing what happens next. Move rupees over from somewhere with room, or let that category be over for the month. Either way it's a decision, not something you find out by accident.

None of this is a new idea. YNAB built an entire company around zero-based budgeting, and it's a genuinely good method. The issue for Indian users was never the method. It's everything wrapped around it.

YNAB charges $109 a year, billed in US dollars, and its bank-sync runs on Plaid, which simply doesn't connect to Indian banks. So you'd be paying a dollar subscription for a feature that doesn't work with your account, and typing every transaction in by hand regardless.

Goodbudget takes a different approach: the envelope method, a relative of zero-based budgeting but not quite the same thing. It's free, which helps, except the free plan tops out at 20 envelopes. Rent, EMI, SIPs, groceries, food delivery, transport, subscriptions, money you send home: that alone can eat most of your twenty before you've made room for anything else.

The India-focused apps come with a different catch. Several of the popular ones work by reading your SMS or notifications to log spending automatically, then make money by layering lending products on top of that data. Fine if what you want is a record of what already happened. Not much help for deciding, in advance, where a rupee is supposed to go.

It matters because the problem behind all this is real: a 2024 IIIT Delhi study found that 74% of UPI users say they've spent more since they started using it.
