How It Works

From a number in your head to a decision you can defend.

We don't just calculate your monthly payment. We run the math your bank won't — stress tests, opportunity costs, and your real affordability score. Here's exactly how.

01

We need to know your real monthly picture.

Before we can tell you anything meaningful, we need a snapshot of your finances. This isn't a credit check. It's the same math you'd do on paper — we just do it faster and more rigorously.

  1. 1

    Monthly Take-Home PayAfter tax, after PF. The number that hits your account.

  2. 2

    Fixed Monthly ExpensesRent, groceries, subscriptions, utilities — the non-negotiables.

  3. 3

    Liquid SavingsMoney you can access within 7 days. Not FD, not mutual funds.

  4. 4

    Existing EMI ObligationsAny loans you're already paying. Car, personal loan, credit card.

Why no bank login?

We never ask for your bank account, UPI PIN, or any credentials. You type the numbers you already know — your salary, your rent, your savings balance. That's it. Nothing leaves your browser session unless you choose to save it.

Tell us what you want to buy.

You're not asking us whether to buy — you're asking whether you can safely afford to. Enter the item, the cost, your down payment, the offered interest rate, and the repayment tenure. We'll show you the real cost the moment you hit enter.

  1. 1

    Purchase CostTotal cost of the item before down payment.

  2. 2

    Down PaymentWhat you're paying upfront. The rest is financed.

  3. 3

    Interest Rate (p.a.)The rate your bank or dealer quoted. We'll use it honestly.

  4. 4

    TenureHow many months or years you'll be paying.

View EMI formula →
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1)

Where:
  P = Principal (Cost − Down Payment)
  r = Monthly rate (Annual rate ÷ 12 ÷ 100)
  n = Tenure in months

A ₹5 lakh loan at 10% for 5 years costs you ₹1.37 lakh in interest alone. The bank shows you the monthly EMI of ₹10,624. We show you the full picture.

03

We give you the verdict — SAFE, CAUTION, or RISK.

The most important number in personal finance isn't your EMI amount. It's your Debt-to-Income ratio — the percentage of your monthly income going toward loan repayments. Banks calculate this before approving your loan. They just never share it with you.

The Formula

DTI Ratio = (Total Monthly EMIs ÷ Monthly Take-Home Pay) × 100
Example:₹22,500 EMIs ÷ ₹75,000 income =30% DTISAFE

What banks don't tell you

Your bank may approve a loan that puts you at 55% DTI. That's their business. Ours is making sure you know what 55% DTI actually means for your life — and what happens when your salary is 3 weeks late.

04

What if the worst month happens?

After you commit to an EMI, life keeps happening. We run four scenarios against your real cash flow to show you how resilient — or fragile — your financial position actually is.

View survival formula →
Months Surviving =
  Liquid Savings ÷ Monthly EMI Obligations

If all income stopped tomorrow, how many
months could you keep paying EMIs before
defaulting?

If two or more of these scenarios put you in the red — reconsider the EMI, or significantly increase your emergency fund first.

If you didn't take the loan — what would you have instead?

This is the question nobody asks. Every EMI you pay is money that could have been invested. We show you the exact wealth you'd accumulate if you put that same monthly amount into a SIP at 12% annual returns — the long-run average of diversified equity mutual funds in India.

View SIP formula →
Future Value (SIP) =
  P × ((1+r)^n − 1) ÷ r × (1+r)

Where:
  P = Monthly SIP (= your EMI amount)
  r = Monthly return (12% ÷ 12 = 1%)
  n = Tenure in months

This does NOT mean "never buy anything." It means: know the real cost of debt. Sometimes the EMI is absolutely worth it. Our job is to make sure you're choosing — not just defaulting into debt.
