Increase your net worth.
Small, sharp tools to help you keep more of what you earn: plan your income tax and loan EMIs, compare what banks really charge to move money between India and abroad, understand the GST on it, and handle invoices and filings — without handing your data to anyone.
The toolbox
Nine tools run right here in your browser. Two more are open-source utilities you run yourself.
Income Tax Calculator
Compare Old and New regime with month-by-month salary entry. Match your payslip, see TDS and in-hand pay through the year, and test how an increment or bonus changes your tax.
EMI & Prepayment Calculator
EMI for any home, car, personal or credit-card loan, with fees and GST for the true total cost, and a month-by-month schedule by financial year. Add lump-sum or regular prepayments and see the interest saved and how much sooner you’re debt-free.
No-Cost & Card EMI Calculator
Buying on EMI at Amazon or Flipkart? See the real cost — GST on interest, processing fee and lost cashback — and a monthly bill that matches your bank’s EMI letter.
SIP, Lumpsum & Retirement
What a monthly SIP (with step-up) or a one-time investment grows to, in today’s money too, and the corpus and SIP you need to retire.
INR → USD Remittance Cost
Sending money abroad for investing or tuition? See the full breakup of markup, SWIFT and processing fees, GST and TCS, and compare banks.
USD → INR Transfer Calculator
See how much lands in your account after fees and exchange-rate margins — compare bank wires with platforms side by side.
Currency Conversion GST
GST on USD↔INR conversion, inward or outward. Enter an amount and see the slab rules applied step by step.
Invoice Generator
Export and domestic GST invoices with a live A4 preview. Separate client and GST copies from one form, then print to PDF.
EDF Generator
Fill the Export Declaration Form for software and services exports. Handles many invoices, validates IEC/PAN/GSTIN, and exports Word, PDF and a bank email.
USD/INR Rate Alerts
A small service that pings you on Telegram when USD/INR hits a new high or low during market hours — no alert spam.
ITR-3 JSON Generator
For professionals and proprietors: combine your prefill JSON with a simple spreadsheet to produce an upload-ready ITR-3 JSON.
Built on three promises
Your data stays yours
The web tools run entirely in your browser. No servers, no logins, and nothing you type is ever sent anywhere (we only count page visits). The EDF generator goes further: its security policy blocks every network call except that visit counter.
Made for India
GST, SAC codes, lakh & crore, FEMA and the ITR-3 schema — the details generic tools get wrong.
Open and honest
Every tool is open source on GitHub. Read the code, fork it, or self-host it.
