The one number that decides everything: your marginal rate
An endowment is a five-year insurance investment wrapper, and its whole appeal rests on a single comparison. Inside an endowment, growth is taxed within the insurer's policyholder fund rather than in your own hands. The income rate this calculator applies inside that fund is a flat 30 percent, and capital gains are taxed at an effective 12 percent. Outside the wrapper, in a normal discretionary unit trust or share portfolio, the same growth is taxed at your personal marginal rate. So the question the tool answers is blunt: is your marginal rate above or below 30 percent? If it is above, the fund's flat 30 percent is a discount and the endowment tends to win. If it is below, you are volunteering to pay more than you need to, and a direct investment usually leaves you richer.
How the policyholder fund actually taxes you
South African insurers run a four-funds tax system, and a retail endowment sits in the individual policyholder fund. The insurer pools your money with other policyholders and pays tax inside that fund before crediting growth to your policy. The effective 12 percent on gains is not a special rate plucked from nowhere. It is the 40 percent capital gains inclusion rate for individuals multiplied by the 30 percent fund income rate, which lands at 12 percent. That is the same 40 percent inclusion this calculator uses on a direct investment, just taxed at the fund's flat 30 percent instead of your marginal rate. These fund rates are the calculator's working assumptions and are exactly the sort of figure to confirm with SARS, the South African Revenue Service, before you lean on them.
R500,000 over ten years at a 41 percent marginal rate
Take the tool's defaults. You invest R500,000, leave it for ten years, and assume 10 percent annual growth. The investment grows to about R1,296,871, a gain of R796,871. The calculator treats that gain as capital in both wrappers. Inside the endowment it taxes the gain at the effective 12 percent, costing roughly R95,624 and leaving about R1,201,247. In a direct investment, the same gain is reduced by the R40,000 annual capital gains exclusion, then 40 percent of the balance is included and taxed at your 41 percent marginal rate, costing about R124,127 and leaving R1,172,744. The endowment comes out ahead by roughly R28,500, which matches the result the tool reports because your 41 percent marginal rate sits above the 30 percent fund rate.
| Step | Endowment | Direct |
|---|---|---|
| Future value before tax | R1,296,871 | R1,296,871 |
| Gain | R796,871 | R796,871 |
| Tax basis | 12% effective | 40% incl. at 41% |
| Tax paid | R95,624 | R124,127 |
| Net value | R1,201,247 | R1,172,744 |
The five-year rule and the liquidity trap
The catch the brochures gloss over is the restriction period. For the first five years you can normally make only one loan or one withdrawal, and it is capped. If you might need the money sooner, the wrapper's tax efficiency is cold comfort against being unable to access your own savings. That is why an endowment suits a high earner with a genuinely long horizon and other liquid savings already in place, not someone who might need the capital next year. The calculator deliberately ignores the restriction period and only compares the tax outcome, so weigh access separately.
Where an endowment still disappoints a top earner
Even at the 45 percent marginal rate, an endowment is not automatically the best home for everything. It uses no annual capital gains exclusion the way a direct investment does, and it offers none of the tax-free growth of a tax-free savings account, which should usually be filled first. A sensible order for a high earner is to max the tax-free savings allowance, use retirement fund contributions for the deduction, and only then consider an endowment for surplus discretionary money. The honest read is that an endowment is a useful tool for the right person and an expensive mistake for the wrong one, so run your own marginal rate through the calculator and confirm the fund rates with SARS before deciding.
Can I name a beneficiary on an endowment to skip the estate process?
Yes, and that is one of the real non-tax advantages. Naming a beneficiary on an endowment can let the proceeds pay out directly to that person and bypass the delays of winding up the estate, although the value may still be brought into the estate for estate duty purposes. It can also offer some protection from creditors after a qualifying period. Treat the estate and creditor benefits as planning points to confirm with an adviser, not guarantees.
Does the 30 percent fund rate change if my income drops in retirement?
No, and that is a downside people miss. The fund rate is fixed inside the insurer regardless of your personal circumstances, so if your marginal rate falls below 30 percent in retirement, the endowment keeps taxing your growth at the higher fund rate while a direct investment would now be cheaper. Endowments reward a stable high earner, not someone whose income is about to fall.
