Prepayment, Part-Payment and Foreclosure: What Each Does

Most advice about paying off a home loan early is motivational. This post is mechanical. There are only three things to understand — how interest accrues, what a prepayment actually does to the schedule, and which of the two elections you are entitled to make — and once they are clear the decision stops being a matter of temperament.

Why the early years of an instalment are mostly interest

An equated monthly instalment is level. What it is made of is not.

Interest in any month is charged on the principal outstanding at the start of that month. Early in the loan the outstanding principal is at its largest, so the interest component of the instalment is at its largest, and only what is left over goes to repaying principal. The next month the outstanding is very slightly smaller, so slightly less of the instalment is interest and slightly more is principal. That shift compounds across the term: by the end, almost the whole instalment is principal.

Nothing about this is a fee or a penalty. It falls out of charging interest on a declining balance while holding the payment level. But it has one consequence people find genuinely surprising: for the first years of a long loan, the outstanding principal falls slowly, and a borrower checking the statement after three or four years often finds they owe nearly what they borrowed.

You do not have to take that on trust, and you should not take it from a table of invented figures either. Put your own principal, rate and term into the EMI calculator and read the amortisation schedule it produces. Look at the interest and principal columns in year one, then in the final year. The shape is the argument.

Part-payment and foreclosure are two different events

A part-payment is a lump sum paid against principal while the loan continues. It reduces the outstanding immediately, and from the next accrual the interest is charged on the smaller balance. The loan survives; something about it changes.

A foreclosure is paying off the entire outstanding and closing the account. It ends the loan, and it triggers a separate administrative process — release of the security, return of the original title documents, satisfaction of the charge in the registry the lender filed it with, and a no-dues certificate.

The two are governed by different clauses in your sanction letter and can attract different treatment, so use the right word when you ask. "I want to prepay" is ambiguous at a service desk; "I want to make a part-payment of a stated amount against principal, with tenure reduction" is not.

The election nobody tells you about

When a part-payment lands, the loan has to be re-cut, and there are exactly two ways to do it.

• Reduce the tenure. The instalment stays where it is; the loan ends earlier. Every month removed from the end of the schedule was a month of interest accrual, and that is where the saving comes from.
• Reduce the instalment. The term stays where it is; the monthly outgo falls. You save the interest on the principal you repaid, but you keep paying for the full original term.

Tenure reduction is the stronger financial outcome of the two, on the same prepayment, for the same borrower. Instalment reduction is the right answer when the monthly figure is the actual problem — a single income in a two-income household, a business going through a thin year, school fees landing at the same time. That is a cash-flow decision, and it is a legitimate one; it is simply not the interest-minimising one.

What matters most is that the election is yours, made explicitly. Many lenders apply a default when a part-payment is received without instructions, and the default is frequently instalment reduction because it is the gentler option to administer. Send the instruction in writing with the payment, and ask for the revised schedule as confirmation that it was applied the way you asked.

Where in the schedule a prepayment does the most work

The saving from prepaying a rupee of principal is the interest that rupee would have attracted for the rest of the time it would have stayed outstanding. So the value of a prepayment is a function of how much term is left, not of how large the outstanding is.

Three practical readings follow.

• Early prepayments dominate. A modest sum in year two can outperform a much larger sum in year twelve.
• Small, regular part-payments compound. An annual bonus routed to principal every year, from the first year, changes the term materially — and each one shortens the base the next one works against.
• Late in the schedule the case weakens. When most of what remains is principal, prepaying mostly moves cash forward in time rather than saving interest, and that money may have better uses.

Charges: the regulatory position, named not quoted

Whether a prepayment costs anything turns on the rate basis of your loan and on the nature of the borrower.

For floating-rate term loans sanctioned to individual borrowers, the Reserve Bank of India has issued directions restricting the levy of prepayment and foreclosure charges. This is the single most important thing for a retail borrower to know, and it is also the thing most likely to have been updated since any given article was written — the directions have been revised more than once, and the scope has moved. The current text is published on the Reserve Bank's own website, and a lender should be able to show you the clause in your sanction letter that reflects it.

For fixed-rate loans the position is different in kind. A lender that fixed a rate has funded itself against an expected term, and prepayment breaks that. Charges are conventional here, and they are contractual — the number, if there is one, is in your sanction letter.

Two things to do before you send the money. Read the prepayment clause in your own sanction letter, and get the lender's confirmation of the applicable charge in writing rather than over a phone line.

Prepay, or invest the same money?

We are not going to answer this for you, because the honest answer depends on figures we do not have and on a risk tolerance that is yours. What we can do is frame it so you can answer it yourself.

A prepayment gives you a certain, known saving: the interest you no longer pay, at the rate on your loan, for the term you removed. An investment gives you an uncertain return. The comparison is therefore not "which number is bigger" but "is the extra expected return worth the uncertainty attached to it, after tax, after charges, and after the effect on your ability to sleep".

Three inputs belong in that comparison and are routinely left out. The tax treatment of both sides — interest on borrowed capital for a house property is dealt with under section 24(b) of the Income Tax Act, 1961, and the treatment of your investment return is its own question, so this is a conversation for a chartered accountant rather than an article. Liquidity, because a prepayment is not reversible: money put into a home loan comes back only through a fresh loan. And your emergency fund, which should be built before any prepayment is made at all.

Where the money for a prepayment should come from

Three sources are commonly used and they are not equivalent.

• Genuine surplus — a bonus, a maturing deposit, the proceeds of an asset you decided to sell. This is what prepayment is for, and routing it to principal in the year it arrives is the whole mechanism working as intended.
• Your emergency fund. Do not. A prepayment cannot be reversed; money put into a home loan comes back only through fresh borrowing, arranged at a moment when you may not be in a position to borrow.
• Another loan. Repaying a secured, long-tenure housing loan with an unsecured, short-tenure, more expensive one is almost always the wrong direction, whatever the monthly figure looks like.

There is a fourth structure worth knowing about, because it achieves much of the effect of a prepayment without the irreversibility: an overdraft-linked home loan, where surplus balances parked in a linked account reduce the interest computed for that period while remaining available to withdraw. It is not offered by every lender and it is not free, so compare it on total cost rather than on the idea. If your lender offers one, ask how the interest saving is computed and what the account costs to run.

The paperwork, at every stage

• Send the part-payment instruction in writing, stating the amount, that it is against principal, and whether you elect tenure reduction or instalment reduction.
• Ask for the revised amortisation schedule after every part-payment, and check that the election was applied as instructed.
• On foreclosure, take a no-dues or loan closure certificate, and keep it permanently.
• Collect every original title document the lender holds, against the list acknowledged when they were deposited.
• Confirm in writing that the charge on the property has been satisfied in the registry the lender filed it with — the loan being closed on the lender's system is not the same event.
• Check your credit information report a couple of cycles later and confirm the account shows as closed.

The last three are the ones people skip, and they are the ones that surface years later when a buyer's lawyer runs a search and finds a charge nobody released. The terms used above are defined in the property glossary, and the shorter answers are on the FAQ page.
