Decision gaps

What most people miss

Four common blind spots that turn perfectly safe-looking decisions into long-term wealth leaks.

Inflation

₹1 crore in 20 years ≠ ₹1 crore today

At 6% inflation, your PPF maturity of ₹1Cr has the purchasing power of just ₹31L today. We show real value, not nominal fiction.

Tenure trap

Lower EMI often means double the interest

Five extra years on a ₹50L home loan can cost ₹18–24L extra. We surface the exact crossover point before you sign.

Tax drag

An FD at 7% is actually 4.9% after tax

Interest income is fully taxable. At a 30% slab, your "safe" FD return collapses. We compute post-tax, post-inflation yield automatically.

Delay cost

Starting SIP 3 years late costs ₹40L

Compounding is brutal when you delay. We calculate the exact rupee cost of every year you wait — making urgency concrete.

How it works

Three steps, zero guesswork

Built for decisions, not just curiosity. Walk into the bank knowing your number — not theirs.

1

Enter your real numbers

Actual loan amount, rate, tenure, income. No inflated defaults that make outputs look rosier than reality.

2

See the hidden costs instantly

Break-even year, inflation-adjusted return, post-tax yield, total interest — updated live as you type.

3

Tune and decide with confidence

Adjust prepayment, tenure, or rate and see exactly how much you save. Negotiate from a position of strength.

Why trust us

We have no reason to mislead you

Most financial tools are built by banks, NBFCs, or commission-earning advisors. We are none of those things.

Transparent math

Every formula is standard, every assumption is visible. Hover any result on the calculator to see exactly how it was derived.

No product push

We never suggest a specific fund, loan, or insurance. The tool surfaces math — the decision stays entirely yours.

Free, permanently

No premium tier, no freemium limit, no trial expiry. Every tool, every scenario, every insight — free, forever.

People who used it

Real decisions, real clarity

What people said after running their numbers through SmartFinance before a major financial move.

I was about to take a 25-year home loan. SmartFinance showed me that 20 years saves ₹14L for ₹3,200 more per month. I renegotiated the same day.

Rahul S. Bengaluru · Home loan

The FD calculator was a wake-up call. My "safe" 7.2% FD was returning 2.8% real after tax and inflation. I moved my money the same week.

Priya M. Mumbai · Fixed deposit

Showed my wife the SIP delay cost — three years late on ₹10K/month means ₹38L less at 60. We started the same week.

Ankit K. Pune · SIP planning

FAQ

Frequently asked

If your question is missing here, it's probably answered inside the calculator you're using.

Is SmartFinance free?

Yes — every calculator is free, with no premium tier, no trial expiry, and no freemium limits. There is no upsell anywhere on the site.

Why post-tax and post-inflation?

Headline returns are nominal. Real outcomes are what you can spend after tax and after 5–7% annual inflation. We model both so the number you see is the number you actually keep.

Do I need to sign up or share data?

No sign-up, no email, no phone. Every calculation runs entirely in your browser and nothing is stored on our servers.

How accurate are the calculations?

We use standard, audited financial math — compound interest, Fisher real return, IT slab rules, amortization formulas. Every assumption is visible right on the calculator page.

Do you sell or recommend products?

Never. We are not a bank, NBFC, or commission-earning advisor. We do not suggest a specific fund, loan, or insurance — we only show the math.

Before you decide

Most people fail at financial planning not because they earn too little, but because they decide with incomplete numbers. Make the next big money choice aware, calm, and evidence-based.
