Why you feel broke on the 20th

You earn decently. The month still ends early.

01

The payday balance lies.

The SMS shows the whole salary. Most of it is already spoken for before you buy a single dinner.

Credited: Rs 75,000.00 → really yours: Rs 29,250

02

The surprises are on a calendar.

Weddings, the flight home, annual renewals. None of them are surprises; they just never make it into the plan.

Cousin's wedding · JanDiwali flight homeAnnual renewal

03

You want permission, not a ledger.

Spending is weekend-shaped. Daily limits break by Saturday; one weekly number holds.

How it works

Fixed. Future. Free.

Three buckets, one honest number. Thirty does the arithmetic on numbers you type in; it never touches your money.

Worked example · take-home Rs 75,000

Monday numberRs 29,250 ÷ 4.33 weeks Rs 6,760

Add a Future item, say a Rs 12,000 Diwali flight three paydays away, and Rs 4,000 a cycle is set aside from Free before your Monday number is worked out.

Fixed

This cycle's commitments: rent and bills, EMIs and card dues, money sent home.

Future

Irregular costs you name, like a cousin's wedding in January or the Diwali flight home, spread across the remaining paydays.

Free

What's left, shown as your weekly Monday number. Spend it however you like.

No bank linking. Never holds or moves money. No ads, no lending, no investment products.

A note from the founder

Why I'm building Thirty

Urvish, founder of Thirty

Building Thirty · the Monday number for your salary

Apparently, my salary lasts until the 18th.

Not because of one ridiculous purchase. I found out by typing six numbers into a 60-second demo for the app I'm building.

Take someone earning Rs 75,000 a month. Before they really start spending, Rs 45,750 may already be spoken for: rent, bills, EMIs, card dues and money sent home.

That's 61% of their salary gone before dinners, cabs, weekends or the wedding they're travelling for next month.

The useful question isn't "What's my monthly budget?" It's "Given everything I already have to pay for, how much can I actually spend this week?"

That's what we're building with Thirty.
