Financial Planning in Your 30s | Cornerstone Series

Welcome to Cornerstone — Temple Alliance’s 10-week financial education series. Each edition is written for a specific life stage or financial situation, designed to be read once and returned to often. We start where the stakes are highest and the window is widest: your 30s.

Your 30s are the decade where financial decisions start to compound — in both directions. The habits you build now, and the mistakes you avoid, have more impact on your ultimate financial position than almost anything you’ll do in your 40s or 50s. The good news is that time is still powerfully on your side. The bad news is that it won’t be for much longer.

Work through this checklist honestly. If you’re ticking most of these off, you’re ahead of the majority of South Africans your age. If several of them sting a little — that’s the point.

Protection

01
You have life cover in place, and the amount is correct. If anyone depends on your income — a partner, a child, a parent — you need life cover. The amount should be enough to replace your income for a meaningful period, settle your debts, and cover your dependants’ future needs. Your employer’s group life cover is almost certainly not enough on its own. Have this reviewed by an adviser, not estimated on a calculator.
02
You have income protection cover. This is the cover most people in their 30s don’t have and most urgently need. Your ability to earn an income is your most valuable asset — worth several million rand over a working lifetime. If illness or injury takes you out of work for six months or two years, what happens? Medical aid covers your hospital bills. Income protection covers your life. Get it while you’re young and healthy, because it becomes harder and more expensive to obtain as you age.
03
Your life and disability cover beneficiaries are correctly nominated. Marriage, divorce, the birth of a child — each of these should trigger a review of your nominations. An outdated nomination can route your life cover to the wrong person entirely, and there is very little your family can do about it after the fact.
04
You have a valid Will. If you’re in your 30s without a Will, you are not unusual — but you are exposed. If you have a partner, children, a property, or any meaningful assets, a Will is not optional. Without a valid Will, the law decides how your estate is distributed — according to a formula that does not know your wishes, does not protect an unmarried partner, and cannot name a guardian for your children. That process can be contested, protracted, and deeply distressing for a grieving family. The consequences of dying without a properly drafted Will are far more costly than the time it takes to have one drawn up. It is one of the most valuable things you can do for the people who depend on you.

Debt

05
You have no short-term consumer debt — or a clear, dated plan to eliminate it. Credit card balances, store accounts, and personal loans are the single greatest destroyers of wealth in this decade. Paying 22% interest on a credit card while earning 10% on an investment is a guaranteed loss. If you are carrying consumer debt, eliminating it is your highest-return financial action — better than any investment.
06
You understand your home loan and are making extra payments where possible. If you own property, even small additional payments against your bond significantly reduce your total interest paid and shorten your loan term. An extra R1,000 per month on a R2 million bond at 10.5% can save you hundreds of thousands in interest over the life of the loan. Ask your bank for the numbers specific to your bond.
07
You are not using debt to fund a lifestyle your income doesn’t support. New car on finance every three years. Overseas holidays on credit. Renovations on a personal loan. These feel manageable monthly — and they quietly destroy the wealth you should be building. If your monthly debt repayments exceed 30% of your take-home pay, that is a red flag that needs immediate attention.

Saving & Investing

08
You are contributing to a retirement fund and have never cashed it out when changing jobs. Cashing out a retirement fund when you change employers is one of the most expensive decisions a person in their 30s can make. The tax hit is severe, the lost compounding is permanent, and the short-term relief rarely justifies it. If you have done this in the past, the priority now is to rebuild — consistently and without interruption.
09
You are contributing at least 15% of your gross income toward retirement. This is the widely accepted benchmark for retiring comfortably at 65 on a similar income. If you’re contributing less, you are either planning to retire later, retire on less, or make up the shortfall later — which gets exponentially harder. Use a retirement calculator with realistic assumptions: 5–6% real returns, 6% inflation, 25 years of retirement income needed.
10
You have a Tax-Free Savings Account (TFSA) and are contributing to it. The TFSA allows South Africans to invest up to R46,000 per year, with a lifetime limit of R500,000, completely free of income tax, dividends tax, and capital gains tax. Over 20 to 30 years, the tax saving is substantial. Every year you don’t contribute, that year’s allowance is permanently gone — you cannot carry it forward or catch it up. If you are not yet using this account, opening one and starting a debit order is the most straightforward financial improvement you can make today.
11
You have an emergency fund covering three to six months of expenses. This is not an investment — it is insurance against life. A sudden retrenchment, a medical emergency, a major car repair. Without an emergency fund, these events become debt events. Keep it in a money market or high-interest savings account — accessible, but not so accessible that you spend it.
12
You understand what your investments are actually invested in. If you have a retirement annuity, a unit trust, or a TFSA, do you know what the underlying assets are? Do you know the fees you’re paying? A 1% difference in annual fees compounded over 30 years can reduce your final retirement value by 20% or more. Fees matter enormously over long periods.

Career & Income

13
You are actively investing in your earning potential. Your income is the engine of your wealth in your 30s. A professional qualification, a relevant postgraduate degree, a skill that makes you harder to replace — the return on this investment often exceeds any financial market. Don’t neglect it in favour of purely financial planning.
14
You have reviewed your salary against market rates in the past 12 months. Loyalty is admirable. Being underpaid by 20% relative to market for five years costs you far more than any investment error. Know your market value.

The one question to sit with

If your income stopped tomorrow, how long could your household sustain its current lifestyle without borrowing? If the answer is less than three months, that is where your financial attention belongs right now — before investment strategy, before offshore exposure, before anything else.

The Psychology of Money

Morgan Housel

The most widely recommended personal finance book of the past decade. It doesn’t tell you which stocks to buy. It makes the case, quietly and convincingly, that financial success has less to do with what you know and more to do with how you behave when things get uncomfortable.
