JEPI vs SPYI: Dividend / Income Calculator Comparison

Which side tends to fit whom

Neither fund is strictly better; they solve different problems. SPYI tends to suit an investor whose priority is the largest current monthly cash flow from a taxable account — the ~12% headline is far higher, and its return-of-capital and §1256 treatment mean comparatively little of that distribution is taxed as ordinary income in the year it is paid. JEPI tends to suit an investor who wants a lower-volatility equity sleeve with a still-substantial payout, and who can hold it inside a Traditional IRA or Roth where its ordinary-income character stops mattering. The calculator does not crown a winner: it lets your own horizon, contribution, and account decide which trade-off reads better on the after-tax and NAV columns, not just on headline yield.

Yield vs growth: what the two distributions actually are

The gap between JEPI's ~8.5% and SPYI's ~12% headline is not a gap in “dividends.” Both funds hold the S&P 500 and sell call options on it, and neither pays a meaningful qualified dividend — that is why both carry the covered-call income label here rather than “dividend,” and why both use a 0% dividend-per-share growth anchor. Their payouts are premium-driven and swing with volatility; treating either as a steadily rising dividend would overstate future income, so the model does not. What separates them is the machinery behind the payout. JEPI writes S&P 500 calls largely through equity-linked notes (ELNs) and distributes the premium, at the lowest expense ratio of the pair (0.35%). SPYI sells S&P 500 index options directly, harvests a larger premium, and pays roughly half again as much — at more than double the fee (0.68%).

The tax split is the real story

Because ELN premium income does not receive qualified-dividend treatment, JEPI's distribution is largely ordinary income, taxed at your marginal rate every year it is paid. That is the heaviest tax character of any income type in this model, which is why so many holders keep JEPI inside a tax-advantaged account. SPYI's index options are instead treated as Section 1256 contracts, taxed 60% long-term / 40% short-term regardless of holding period, and a large share of each SPYI distribution is often classified as return of capital, which defers tax and lowers your cost basis until you sell. In a taxable account that makes SPYI's distribution comparatively light on annual tax despite being far larger — but return of capital is a deferral, not a gift: a reduced basis means a bigger capital gain when you eventually sell. Switch the Account toggle to watch the after-tax column separate; the ordinary-income drag on JEPI and the deferral on SPYI move in opposite directions, and a Traditional IRA or Roth erases both.

NAV erosion and the total-return difference

A higher headline yield is not a higher total return. A large covered-call distribution can exceed what the underlying can sustainably earn, so the model applies a NAV-erosion drag that grows with the yield — larger for SPYI's ~12% than for JEPI's ~8.5%. That is why the Portfolio value column can favor the lower-yield fund even when the income column favors the higher one, and why the crossover callout matters: over a long horizon a fuller-but-flatter payout and a smaller one that compounds against less NAV drag can trade places. Both funds also cap equity upside with the calls they write, so each structurally trails the plain index it holds during long bull runs — the preset uses a deliberately modest price-growth assumption (2% for JEPI, 3% for SPYI) to reflect that. Read all three columns together: income now, value later, and tax kept. The two funds rarely lead on all three at once, and which combination fits is a personal call, not a ranking. Figures are illustrative and dated as of 2026-06; forward growth inputs are editorial preset assumptions, not predictions, and none of this is investment or tax advice.
