₱5,000 a month in the S&P 500 for 10 years: ₱600,000 became ₱1.51 million
If you had put ₱5,000 into the S&P 500 every month from October 2016, you would have ₱1,508,625 in September 2026 — 2.51 times what you paid in. In US dollars it was only 2.15 times; the weaker peso made up the difference. Plus the Nasdaq-100 over 20 years, timing, lump sum and Philippine tax points.
“Just put money into the S&P 500 every month” is advice you will hear from almost every personal-finance page. So what did it actually produce for someone in the Philippines who started ten years ago, paying in pesos? We ran the numbers with the real exchange rate on each purchase date. The short answer: ₱600,000 became ₱1,508,625 — and a good part of that came from the peso, not from the index.
How much is ₱5,000 a month in the S&P 500 for 10 years worth now?
₱1,508,625 on 25 September 2026, or 2.51 times the ₱600,000 paid in, for someone who bought ₱5,000 of the S&P 500 on the first US trading day of every month from October 2016 to September 2026. The money-weighted annual return (XIRR) was 17.6% in pesos. This is the price index converted at the BIS daily peso–dollar rate, before dividends, fees and taxes (FRED SP500; BIS).
S&P 500, ₱5,000 on the first US trading day of each month, October 2016 to September 2026 (120 purchases), valued at the 25 September 2026 close and ₱62.4783 per US dollar (BIS daily). Price index; dividends, fees and taxes excluded.

Multiple
Shared linear scale from zero. Selected entries from the table below. Its dates, units, definitions and limitations still apply.
| Index (10 years, ₱600,000 paid in) | Value on 25 Sep 2026 | Multiple | Annual return (XIRR) | Multiple in US$ |
|---|---|---|---|---|
| S&P 500 | ₱1,508,625 | 2.51× | 17.6% | 2.15× |
| Nasdaq-100 | ₱2,095,435 | 3.49× | 23.7% | 2.98× |
How we calculated it. Each month, ₱5,000 is converted into US dollars at the BIS daily rate for the purchase date (or the previous available day) and used to buy the index at that day's close, in fractions where needed. Purchases run from 3 October 2016 to September 2026. Values are the index closes on 25 September 2026 converted back at ₱62.4783. The annual return is an XIRR, which accounts for the date of every payment, so it is not comparable with a simple "total return ÷ 10".
Your ₱5,000 bought about US$93.79 a month on average. That small number matters later, because the gap between what the dollar cost when you bought and what it was worth when you checked is a big part of this story.
What if you had started 20 years ago?
With the Nasdaq-100, ₱1.2 million paid in from October 2006 (240 purchases of ₱5,000) became ₱13,012,098 on 25 September 2026 — 10.84 times the money paid in, with an XIRR of 20.4% in pesos (FRED NASDAQ100).
| Plan | Paid in | Value on 25 Sep 2026 | Multiple | XIRR | Multiple in US$ | Average purchase rate → valuation rate |
|---|---|---|---|---|---|---|
| Nasdaq-100, 20 years | ₱1,200,000 | ₱13,012,098 | 10.84× | 20.4% | 8.45× | ₱48.66 → ₱62.48 |
The S&P 500 series we use starts in October 2016, so there is no 20-year S&P 500 figure on the same basis. The Nasdaq-100 result covers one of the strongest 20-year runs any major index has had; treat it as a record of what happened, not as a typical outcome.
Does the result depend on when you check?
Yes, a lot. The same plan, started in October 2016 and checked on three dates, gives quite different multiples, because both the index and the peso moved in between.
| Valuation date (₱ per US$) | Paid in by then | S&P 500 | Nasdaq-100 |
|---|---|---|---|
| 31 Dec 2024 (₱58.0431) | ₱495,000 | ₱971,177 (1.96×) | ₱1,245,359 (2.52×) |
| 31 Dec 2025 (₱58.9498) | ₱555,000 | ₱1,216,520 (2.19×) | ₱1,590,082 (2.87×) |
| 25 Sep 2026 (₱62.4783) | ₱600,000 | ₱1,508,625 (2.51×) | ₱2,095,435 (3.49×) |
Between the end of 2025 and 25 September 2026 the S&P 500 rose from 6,845.50 to 7,743.41 and the peso weakened from ₱58.95 to ₱62.48 per dollar. Both pushed the peso value up in the same nine months. A result measured right after a strong stretch for both looks better than one measured a year earlier, and the reverse can happen just as quickly.
How much did the weak peso add?
About ₱221,000 of the S&P 500 result, or roughly 17%. In US dollars, the plan turned US$11,255 into US$24,146, a multiple of 2.15. In pesos the multiple was 2.51, because the dollars were bought at an average of ₱53.3116 and valued at ₱62.4783 (BIS daily rates).
| Measure | S&P 500, 10 years | Nasdaq-100, 10 years | Nasdaq-100, 20 years |
|---|---|---|---|
| Dollars bought | US$11,255 | US$11,255 | US$24,661 |
| Dollar value on 25 Sep 2026 | US$24,146 | US$33,539 | US$208,266 |
| Multiple in US$ | 2.15× | 2.98× | 8.45× |
| Multiple in ₱ | 2.51× | 3.49× | 10.84× |
| Average purchase rate → valuation rate | ₱53.31 → ₱62.48 | ₱53.31 → ₱62.48 | ₱48.66 → ₱62.48 |
If the peso had stayed at its average purchase rate, the S&P 500 plan would be worth about ₱1,287,000 (US$24,146 × ₱53.3116) instead of ₱1,508,625. The rest, about ₱221,000, is the exchange-rate effect. For the 20-year Nasdaq-100 plan the effect is larger, because the gap runs from ₱48.66 to ₱62.48.
This works in both directions. A peso investor in US stocks holds two positions at once: the index, and the dollar. The weaker peso of 2024–2026 — the 2026 annual average so far is the weakest on record — flattered this result. If the peso strengthens from here, the same holdings will be worth fewer pesos even if the index does not move.
What if you had put it all in at once?
A lump sum did better in this period. ₱600,000 put into the S&P 500 on 3 October 2016, at ₱48.2191 per dollar, would have been worth ₱2,785,470 on 25 September 2026, or 4.64 times. For the Nasdaq-100 the lump sum gives ₱4,889,558 (8.15 times).
| ₱600,000, S&P 500 | Value on 25 Sep 2026 | Multiple |
|---|---|---|
| Monthly, ₱5,000 × 120 | ₱1,508,625 | 2.51× |
| All at once on 3 Oct 2016 | ₱2,785,470 | 4.64× |
This is not a fair contest. The lump sum had all the money invested for the full ten years and bought dollars at ₱48.22, while the monthly plan put in its last payments only weeks before the valuation date. In a market that mostly rose, money invested earlier simply had more time. Monthly investing exists for a different reason: it fits money that arrives monthly — a salary, a remittance — and it avoids putting everything in just before a fall.
Taxes and options for Philippine residents (as of October 2026)
The figures above ignore tax. In practice there are two layers — US tax at source and Philippine tax at home — and the rules below are the ones we could confirm in primary texts as of October 2026.
US withholding on dividends. The US generally taxes US-source income paid to foreign persons at 30% (IRS). The US–Philippines income tax treaty lowers the general rate on dividends to 25% (20% for qualifying corporate shareholders), according to the IRS treaty table (IRS Table 1). US brokers ask foreign individuals for Form W-8BEN; whether you get the treaty rate depends on what you claim and qualify for. The price-index results in this note include no dividends at all, so the withholding reduces income that is not counted here.
Philippine tax on gains. Under Section 23 of the Tax Code, a citizen residing in the Philippines is taxable on income from sources within and outside the Philippines, while an overseas contract worker is taxable only on Philippine-source income (RA 8424, Sec. 23). RA 12214, the Capital Markets Efficiency Promotion Act signed on 29 May 2025, rewrote Section 24(B)(3): a 15% final tax applies to net capital gains from shares “in a domestic or foreign corporation”, except shares sold through a local or foreign stock exchange that are subject to stock transaction tax. The foreign-exchange stock transaction tax in the amended Section 127(B) is written for shares of domestic corporations (RA 12214). On a plain reading, that places gains on US-listed shares in the 15% bracket, but we did not find BIR guidance that deals specifically with US shares or ETFs held at a foreign broker. Confirm the treatment with the BIR or a tax adviser before you file.
Funds sold in the Philippines. You do not need a US brokerage account to own US index exposure. BSP rules allow a unit investment trust fund (UITF) to operate as a feeder fund or a fund-of-funds, that is, a fund that invests through another collective investment scheme (BSP Circular No. 876), and several banks offer UITFs and mutual funds that invest in US equity funds. RA 12214 also excludes from gross income the gains an investor realises on redeeming mutual fund shares or UITF units, provided final taxes on realised gains were already withheld at the level of the underlying assets (RA 12214, Sec. 32(B)(7)(h)). Fees, currency of the fund and tracking differ by product, so compare the plan rules rather than the label.
What these numbers cannot tell you
This is a record of one ten-year and one twenty-year window, not a forecast. The S&P 500 and the Nasdaq-100 had an unusually strong decade, and the peso weakened over the same period; neither is guaranteed to repeat. The results use price indices without dividends, and exclude broker fees, fund expenses, foreign-exchange spreads and taxes, all of which lower a real investor's result. Real purchases cannot happen at the exact closing price and BIS rate used here; bank and remittance rates include a spread. The BIS daily average can differ by a few centavos from the BSP reference rate.

Questions & answers
How much would ₱5,000 a month in the S&P 500 for 10 years be worth now?
Investing ₱5,000 on the first US trading day of every month from October 2016 to September 2026 (120 purchases, ₱600,000 in total) gives ₱1,508,625 on 25 September 2026, 2.51 times the amount paid in. That is the price index converted at the BIS daily peso rate, before dividends, fees and taxes.
What was the annual return of peso cost averaging into the S&P 500?
The money-weighted annual return (XIRR, using the actual date of each purchase) was 17.6% in pesos for October 2016 to September 2026. In US dollars the plan grew 2.15 times rather than 2.51 times, so part of the peso return came from the exchange rate rather than from the index.
Did the weak peso help or hurt a US stock DCA plan?
It helped this plan. The peso averaged ₱53.31 per dollar across the 120 purchases and stood at ₱62.48 on the valuation date, so each dollar of value converted into about 17% more pesos. Without that move the S&P 500 plan would have been worth about ₱1.29 million instead of ₱1.51 million. A stronger peso would have worked the other way.
Is monthly investing better than putting the money in all at once?
Not in a market that mostly rose. ₱600,000 put into the S&P 500 on 3 October 2016 would have been worth ₱2,785,470 (4.64 times) on 25 September 2026, against ₱1,508,625 for the monthly plan. The comparison is not like for like: the lump sum assumes you had all the money at the start, while the monthly plan matches how most salaries and remittances arrive.
Do Philippine residents pay tax on US stock investments?
Yes, on both sides. The US withholds tax on dividends paid to foreign persons, 30% by default and 25% at the US–Philippines treaty rate listed by the IRS. On the Philippine side, resident citizens are taxed on income from all sources, and RA 12214 sets a 15% final tax on net gains from shares of domestic or foreign corporations, with an exception for exchange-traded shares covered by stock transaction tax. Confirm how this applies to your account with the BIR or a tax adviser.
