How do I calculate the monthly payment on a personal loan?
Personal loan monthly payment is not “principal ÷ months.” It is an EMI formula—and the first number your salary should meet before you sign.

The brochure shows “easy EMIs.” Your salary shows the truth
A fintech app said ₹3 lakh personal loan is “just ₹10,500 a month.” They forgot you still eat.
At 14% for 3 years, ₹3 lakh lands near ₹10,276 EMI. That is ₹69,936 of interest on top—more than a year of the EMI itself.
If you skip this step, the rest is theatre.
Indore kitchens already know this. Relatives on the group chat are slower.
It is arithmetic plus behaviour. The arithmetic is easier.
Banks quote reducing balance. Some apps quote flat rate and dress it up. Always ask which one you are signing.
Discomfort here is a signal. A 15% slider is not.
Interest does not care that you meant to pay more next month.
Type loan, rate, tenure—then read total interest
Grab principal, annual rate, tenure in months. Plug into EMI = P × r × (1+r)^n / ((1+r)^n − 1) with r = rate/12/100.
Or skip the algebra: use the personal loan EMI widget below with ₹3,00,000, 14%, 36 months.
Open a calculator and type the ugly version first—₹10,276 EMI on ₹55,000 take-home with ₹8,000 rent is not “affordable” because an algorithm green-lit it.
Type the version that would still stand after a bad bonus year.
Then scroll total payment. If interest is more than 35% of principal, ask whether this purchase can wait.
Processing fee of 2% on ₹3 lakh is ₹6,000 gone before month one. Add it to “true cost,” not to Instagram.
If you cannot explain the result to a slightly impatient parent, you do not understand it yet.
Where people mess up the monthly payment math
Dividing ₹3 lakh by 36 and calling it ₹8,333. Interest exists. Flat-rate marketing exploits this.
Comparing only EMI across lenders and ignoring processing fee, insurance add-on, and prepayment lock-in.
Taking max tenure to “reduce EMI” on a depreciating wedding or phone. You bought time, not relief.
A rule of thumb is a starting fence, not a closing argument.
Your cousin’s 2017 small-cap luck is not a policy.
Change the input when life changes. Loyalty to old Excel is how people drift.
People in Indore skip that and then call the failed plan “the market.” It was the skipping.
Clean the loan before you hunt for “low EMI”
Need ₹3 lakh for medical: shorter tenure if cash flow allows; compare two NBFC quotes on total outflow.
Consolidating cards: monthly payment must beat combined minimums *and* leave room for no new swipes.
If EMI crosses 15% of take-home for discretionary spend, shrink the ticket or delay.
Buffer first, ugly debt second, this goal third. Reverse it and the goal becomes a loan.
Investing while revolving a 36% card is theatre.
A thinner SIP or a slower prepay still exists. A six-month disappear does not.
A smaller SIP or a shorter loan goal beats a heroic screenshot you cancel in six weeks.
₹3 lakh at 14% for 36 months
₹3L / 14% / 3y → ~₹10,276/mo, ~₹3.7L total. That ₹70k interest is real groceries.
Same loan at 16%: EMI ~₹10,547, total ~₹3.8L. Two points moved ₹9,000.
₹5L at 15% for 5y: ~₹11,895/mo, interest ~₹2.1L. “Small EMI” is a long marriage.
If someone sells the same figure as a guarantee, walk.
If the plan only works at 18% returns or a 6% home loan forever, it is not a plan.
Good years are a bonus. Plans that need good years are costumes.
Keep a 10% haircut for tax, fees, or the extra month the builder delays.
Run it once, then run it at +1% rate stress
Monthly payment is a kitchen number. Total interest is the number you tell your future self.

Boring consistency beats a dramatic restart every January.
Calendar reminder beats a quote about discipline.
If a friend in Indore asks the same thing next month, send them the calculator link, not a lecture.
And please date your spreadsheet. Future you will not remember which fantasy version this was.

Quick answers
What is the formula for personal loan monthly payment?
EMI = P × r × (1+r)^n / ((1+r)^n − 1), where P is principal, r is monthly rate (annual/12/100), n is months.
Does processing fee change the EMI?
Usually fee is deducted upfront or added to principal. Either way it raises true cost—factor it separately.
Is a longer tenure always better for monthly payment?
It lowers EMI but raises total interest. Personal loans are rarely “good debt”—don’t stretch for comfort.
