What most people miss

Inflation

₹1 crore in 20 years ≠ ₹1 crore today

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

Tenure trap

Lower EMI often means double the interest

A 5-year longer tenure on a ₹50L loan can cost ₹18–24L extra. We surface the exact crossover point before you sign anything.

Tax drag

FD at 7% is actually 4.9% after tax

Interest income is fully taxable. At the 30% bracket, your ‘safe’ FD returns collapse. 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, not abstract.

Choose your goal

Each tool shows what most calculators hide.

EMI

See your real monthly burden, when interest gives way to principal, and the exact year your loan stops costing more than it's worth.

SIP

See how starting today vs 3 years later changes your final corpus by lakhs. Compare lump sum vs disciplined monthly investing side by side.

PPF

Tax-free doesn't mean risk-free from inflation. See the real extension strategy, the 15-year lock-in tradeoff, and true post-inflation return.

FD

Reveals the headline rate illusion. Post-tax, post-inflation, your 7% FD often returns under 3% real yield. Know before you lock in.

RD

Track maturity vs inflation-adjusted goals. See if your monthly deposit is actually keeping pace with the cost of your target purchase.

SSY

Understand the contribution window vs growth window gap — how corpus grows for 6 years after contributions stop, before maturity.

How it works

Three steps, zero guesswork

Built for decisions, not just curiosity. You arrive at the bank knowing your number — not theirs.

See the hidden costs instantly

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

Tune and decide with confidence

Adjust prepayment, tenure, or rate and see exactly how much you save. Walk into any negotiation fully prepared.

People who used it

Real decisions, real clarity

What people said after using SmartFinance before a major financial move.

I was about to take a 25-year home loan. SmartFinance showed me that 20 years saves ₹14L with only ₹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 giving 2.8% real return after tax and inflation. Moved to a better instrument immediately.

Priya M. Mumbai · Fixed deposit

Showed my wife the SIP delay cost — starting 3 years late on ₹10K/month means ₹38L less at 60. We started the same week.
