About Unowe

Unowe is a free, private debt-payoff and investment planner built for borrowers in India. The name is simply un-owe — to stop owing. That is the whole aim of the tool: to get you to the month where you owe nothing, sooner than your EMIs alone would manage.

What it does

You enter your loans, income and expenses. Unowe sequences every loan and card by interest rate, works out how much to send at principal each month, sizes an emergency fund, and allocates whatever surplus remains across equity, debt, gold and liquid buckets.

  • A debt-avalanche prepayment plan, with prepayment penalties and lock-ins handled honestly
  • Prepay versus invest break-even, including the §24b deduction cap most calculators ignore
  • Old versus new tax regime for FY 2026-27, with the §87A and surcharge marginal relief applied
  • A monthly progress log, and a PDF report that doubles as a backup of your plan

Why it keeps your figures on your device

Financial detail is about as sensitive as personal data gets, and the safest place to put it is somewhere nobody can be breached out of. Your balances, income and loans are encrypted with AES-256-GCM in your own browser, using a key derived from your password. The server holds your email and a password hash so you can sign in — nothing else. There are no third-party trackers and no analytics.

The honest trade-off: because nothing is stored on a server, nobody can recover your plan for you if you lose both your password and your recovery key. That is why the tool pushes you to export a PDF or JSON backup, and why it refuses to sign you out when an edit has not been saved.

What it is not

Unowe is an educational planning and calculation tool. It is not a registered investment adviser, is not SEBI- or IRDAI-registered, and does not provide personalised financial advice. It does not hold your money, move your money, or connect to your bank. Every figure it shows is arithmetic on the numbers you typed in, and you should check anything material against your own lender's terms before acting on it.

Where it is deliberately different

Most Indian financial calculators are lead-generation. They are free because the answer is the beginning of a sales conversation, and the arithmetic is often simplified in whichever direction suits that. Unowe sells nothing, is not paid a referral fee by any lender, insurer or fund, and names no product. That removes the reason to round in anyone’s favour, and it shows up in three places where the common shortcuts are simply wrong:

  • The prepay-versus-invest break-even. The usual formula is loan rate × (1 − tax rate), which assumes every rupee of home-loan interest earns you a deduction. Section 24(b) caps that at ₹2 lakh a year on a self-occupied house, so above the cap the shortcut overstates the case for investing. Unowe computes the honest bar and says when the shortcut would have misled you.
  • Marginal relief. Just above the ₹12 lakh rebate threshold a naive slab table shows a few hundred rupees of extra income triggering tens of thousands in tax. Section 87A marginal relief exists precisely to remove that cliff, as does its counterpart for surcharge at ₹50 lakh and above. Both are applied here; many calculators apply neither.
  • Interest saved against a loan that never ends. Where EMIs alone would not clear the debt within the projection horizon, the tool shows a dash rather than a figure. A saving measured against a loan with no end date is not a saving.

How to check any of this

Nothing here has to be taken on trust. Every engine — amortisation, avalanche sequencing, the tax regimes, the break-even, credit-card payoff — is a pure function covered by unit tests, and the numbers on every page come from those same functions rather than from copy written separately. The site ships under a strict Content Security Policy with no third-party scripts, which you can confirm in your browser’s network tab: nothing loads from anywhere but this domain, and no request carries your figures anywhere at all.

If you would rather see it working than read about it, the demo loads a sample household with no signup, and Unowe Academy walks through the whole tool in four short parts with a full transcript on the page.

What it costs

The planner is free and stays free, and so is the JSON backup that holds every figure — your own data is never behind the paywall, because nothing is stored on a server and charging for the way out would be holding it hostage. A one-time ₹199 unlocks the formatted PDF report. There is no subscription, no upsell and no advertising — which is also why there is no incentive here to steer you toward any particular product.
