Child marriage corpus — when and how to build it

Building a corpus for a child's marriage is a goal many Indian parents take on, though the size and necessity vary enormously by family values. Unlike education (which has a relatively standard cost profile), marriage costs span a huge range — from ₹5 lakh for a simple court marriage to several crores for an elaborate destination wedding. The planning framework is the same; the target is personal.

The decision about whether to plan for it

Some families consider marriage corpus a parental obligation; others let the child pay their own way; many sit in between. There is no universally correct answer. Considerations:

• Family tradition: some families have an unspoken expectation around the parents funding the wedding.
• Child's preferences: as children grow into adults with their own income, they may prefer to plan their own wedding to their own taste.
• Relative priorities: the same corpus could fund a more comprehensive retirement, more education support, or a wedding. Choose explicitly.
• Cultural expectations: some regions have specific norms around gifts, gold, dowry-like (illegal) practices. Be deliberate about which to participate in.

The target size

Indian wedding cost ranges, broadly:

• Simple ceremony + court registration: ₹1-3 lakh.
• Modest family wedding: ₹5-15 lakh.
• Moderate wedding with reception: ₹15-50 lakh.
• Elaborate wedding: ₹50 lakh - 2 cr.
• Destination / high-budget: ₹2-10 cr.

Decide today's cost based on your values, then project forward.

Projection math

If you target ₹30 lakh in today's prices for a child currently age 5, the wedding might happen around age 28 (23 years away). At 7% wedding-related inflation: ₹30 lakh × (1.07)^23 ≈ ₹1.43 cr nominal.

SIP needed at 11% CAGR over 23 years to reach ₹1.43 cr: approximately ₹14,000 per month flat. With step-up SIP starting at ₹7,000 and rising 10% annually, similar outcome.

Why use SIPs for this goal

Long horizon, defined target, predictable monthly cash outflow — fits the SIP structure naturally. No real alternative gives you the equity exposure needed to outpace 7% inflation while letting you contribute incrementally.

Bank FDs at 6-7% don't even keep pace with wedding-cost inflation. Gold (often used for marriage in Indian tradition) is volatile and yields lower long-run real returns than equity. Real estate is too illiquid for a goal with a known target date.

Asset allocation glide path

• Years 0-18 of the SIP: 75% equity, 25% debt.
• Years 18-22: gradually shift to 50% equity, 50% debt.
• Years 22-23: almost entirely debt and liquid, ready to deploy.

Combining with other goals

For families building corpus for both education and marriage:

• Education target hits at child age 18 — 13 years for a 5-year-old.
• Marriage target hits at child age 28 — 23 years for a 5-year-old.

The two goals can share an SIP for the first 13 years, then split. As education needs are met, the marriage corpus continues to grow for another 10 years. Some families find this overlap helpful; others prefer separate explicit SIPs from the start for clarity.

Cultural artifacts to budget for

Wedding planning often involves specific items: gold for jewellery, real estate for setting up the new home, vehicle, etc. Some of these are gift-tradition items the parents fund; others are couple's own responsibility. Be explicit with your child as they approach adulthood about what you will and will not fund — managing expectations avoids friction.

The gold question

Many Indian families layer some gold accumulation into the marriage corpus through Sovereign Gold Bonds (tax-free at 8-year maturity), gold mutual funds, or gold ETFs. SGB 2.5% annual interest accumulates. The corpus thus has both equity and gold components — gold serves as an inflation hedge plus a culturally-symbolic asset.

If you plan to fund the actual wedding gifts through SGB redemptions, time the SGB purchases so they reach 8-year maturity around the wedding date.

What to communicate to the child

As your child becomes an adult and starts earning, share the marriage corpus plan. Some children may want to add their own contribution; others may want to redirect the parental fund elsewhere (down payment for a flat, business capital, etc.). Treating it as discretionary family money rather than a fixed expectation often produces better outcomes.

Modern marriage trends

The "moderate" tier of weddings (₹15-50 lakh range) has been growing in Indian cities as preferences shift toward smaller, more personal celebrations. Court marriage with a small reception is increasingly common among young professionals. Planning for the moderate scenario as base case gives you flexibility to upgrade if desired.

If the child marries later or doesn't

The corpus is not locked in. If the child marries later than projected, the corpus continues to grow. If they choose a smaller wedding, the residual becomes a starter fund for the couple's home, savings, or your retirement enhancement. Plan for the corpus to be flexible.
