Indonesia's Muslims Give Rp343 Trillion a Year — Voluntary Sadaqah Dwarfs Zakat, First National Survey Since 2003

The first comprehensive national survey of Muslim charitable giving in Indonesia since 2003 has put a real number on what the world's largest Muslim-majority country actually gives: Rp343.08 trillion (about $21 billion) in zakat, infak, sadaqah, waqf and qurban in a single year — with infak and sadaqah alone accounting for Rp221.7 trillion, more than eight times the zakat maal total. Released June 5–7, 2026 by the Social Trust Fund of UIN Syarif Hidayatullah Jakarta with pollster Indikator, the survey covered 8,360 Muslim respondents across all 34 provinces with a margin of error of ±1.4%.

What did the 2026 Indonesia ZISWAF survey actually find?

The headline is that voluntary giving dwarfs the obligatory. The full breakdown of estimated annual Muslim giving in Indonesia:

Category	Annual value (Rp)	Share
Infak / sadaqah	221.73 trillion	64.6%
Qurban	52.32 trillion	15.2%
Waqf	33.58 trillion	9.8%
Zakat maal	27.04 trillion	7.9%
Zakat fitrah	8.42 trillion	2.5%
Total ZISWAF + qurban	343.08 trillion	100%

The finding reframes a long-standing assumption. Earlier estimates had pegged Indonesia's national ZISWAF potential as high as Rp500 trillion a year. This survey — the first to measure realised giving rather than modelled potential since 2003 — comes in lower, but it is grounded in what 8,360 households actually reported spending, not a macroeconomic projection. The researchers argue it is closer to the truth of what Muslims in Indonesia actually practise.

Why does voluntary giving exceed obligatory zakat in the data?

Because sadaqah has no ceiling. Zakat maal is a precise 2.5% on qualifying wealth above the nisab, calculated once a year — a bounded, rule-based obligation. Sadaqah and infak are open-ended: any amount, at any time, for any permissible cause, and the cultural habit of giving small sums frequently — at the mosque, to a neighbour, to a fundraiser, on a Friday — accumulates across a year into a figure no single zakat payment can match.

This is the lived shape of sadaqah jariyah — continuous, voluntary charity whose reward, in the Islamic tradition, keeps accruing after the giver has stopped. The survey is among the first to quantify just how much larger that voluntary stream is than the obligatory one in a single Muslim-majority economy.

How was the survey conducted?

The Social Trust Fund (STF) of UIN Syarif Hidayatullah Jakarta ran the study with pollster Indikator Politik Indonesia, under the Commission on Asian Philanthropy and with support from the Ministry of Religious Affairs' Directorate of Zakat and Waqf Empowerment, Dompet Dhuafa, and Voyage. Fieldwork ran 20 January to 5 February 2026, using stratified multistage random sampling across all 34 provinces, with 8,360 Muslim respondents aged 18 and above. The margin of error is ±1.4% at a 95% confidence level.

The researchers note it is the first survey to comprehensively map Indonesia's Islamic philanthropy landscape since 2003 — a period in which the number and diversity of actors, channels, forms and programmes all changed substantially.

What does this mean for how families plan their giving?

The survey quietly confirms something every household already senses: the giving that compounds is the giving that is organised. Rp343 trillion does not flow from a single annual decision; it flows from thousands of small, repeated choices made across a year — and from the infrastructure (mosques, waqf institutions, online platforms, zakat collection agencies) that makes each one frictionless.

The same logic applies at the family level. A household that records its giving alongside its assets, sets its zakat obligation against its real wealth each year, and leaves its sadaqah intentions documented gives its heirs something more useful than a memory of generosity: it gives them a practice to continue. Sadaqah jariyah — continuous charity — is, by definition, giving that outlives the giver, but only if the next generation knows it was happening and where it was directed.

Where WiseEnding fits

A national survey can total what a country gives in a year; it cannot tell a single family what they gave, what they owe in zakat, or what they intended their giving to support after them. That layer is still handmade, household by household.

WiseEnding's My World is built for it: a zero-knowledge vault where the full inventory — assets, debts, documents, and the giving record alongside them — is kept current while you are here, encrypted so only you can read it. The optional Islamic layer tracks Zakat against each asset and lets sadaqah intentions be recorded so they reach the people you chose when your silence becomes permanent. The survey measures the ocean. Your vault is the channel that keeps your own stream flowing to the people and causes you named.

Indonesia gives Rp343 trillion a year — most of it voluntarily, most of it unrecorded at the household level. The giving that survives a generation is the giving that was written down.
