Three years ago you worked out what you could spare each month and set up a standing instruction for that amount. Since then you have had two increments and changed jobs once. The rent went up, you upgraded the phone, the family started eating out more often. The standing instruction is still for the same amount.
This gap is almost never deliberate. Nobody decides to stop increasing what they set aside — a standing instruction is designed to be forgotten, and it does that job perfectly.
Most people spend their raise before they have decided to
Money you have never had in your hands is easy to redirect. Money you have been living on for a year is not. When income goes up, spending follows it quietly — a slightly better flat, a car loan that now looks affordable, a subscription here and there. Within months the higher income feels like the normal income, and the extra has vanished into a standard of living you would find uncomfortable to give up. The timing is what matters: a raise is easiest to redirect in the month it arrives, and harder every month after.
So the useful moment is the appraisal letter, not January. Divert part of an increase at the point it lands and the household budget never adjusts to it, so nothing has to be given up. Not discipline in the painful sense — just sequence.
Most fund houses have a mechanism for this
The facility usually goes by a name like step-up or top-up. It is an instruction attached to a Systematic Investment Plan — a fixed monthly contribution to a fund — that raises the amount automatically once a year, by a percentage or a fixed rupee figure. You can equally do it by hand, with a calendar reminder for the month your appraisal lands. The automatic version exists because the manual version is the sort of thing people intend to do and don't.
Whether it is offered, what it costs and what the minimums are differ from one fund to another, so check the scheme documents rather than assuming.
What raising the contribution actually changes
Take a contribution that goes up by 10% each year and compare it with the same contribution held flat. This is arithmetic on your own money going in — not a return, not a projection, and it says nothing about what any investment will be worth.
- After ten years, the monthly amount you are putting in is roughly two and a half times where it started.
- Over those ten years, the total amount contributed is around 60% more than if the instruction had never been touched.
That difference came from raising a number once a year at a moment when raising it cost you nothing. Hold it up against where most people spend their attention: choosing between one fund and another, comparing past performance tables, switching after a bad year. Whatever that effort is worth — and past performance is a poor guide to what comes next — it works on the return side, which nobody controls. The size of the contribution is the other side of the equation, and it is the side you decide.
The honest limits
This does not make an investment safe. A larger amount going into a volatile asset is a larger amount exposed to that volatility, and the value can fall.
Nor should it run ahead of the rest of your finances. Committing a larger share of your income to a long-term contribution is the wrong move if it costs you an emergency buffer, or while an expensive loan is outstanding, or if you may need the money within a few years. An escalation you have to cancel in a difficult year has cost more than it gained.
And there is no single right percentage. 10% is a round number that reads well in a headline, not a rule. What suits you depends on how your income moves, what your commitments are and how much slack you need — a decision to work through for yourself, or with someone qualified and registered to advise you.
