Can anyone please tell me the algorithm for the pledge calculation -
up to $1M?

If possible could you please also include info on the multiplication
for different currency and std of living/purchasing power?

It used to be on the website but has been replaced with an auto-
calculator (which is very useful). I looked for a cached version but
could not find it.

I recommend the calculation info should be at the bottom of the
webpage in a section entitled "How is this calculation made".

I also suggest that it show the calculated final percentage that is
recommended (rec donation/salary x 100).

I am trying to understand the detail of the calculation

My partner and I currently give 5.5% of our pre-tax salary in
donations (Oxfam/Fred Hollows and PSI) and want I was wondering how
this compares with Mr Singer's recommendation.

Lucian,

As far as we can see, the information you are seeking is already there on the pledge page, as follows:

The Standard

Income Bracket	Donation
Less then 105 000 USD	At least 1% of your income, getting closer to 5% as your income approaches 105 000 USD
105 001 USD – 148 000 USD	5%
148 001 USD – 383 000 USD	5% of the first 148 000 USD and 10% of the remainder
383 001 USD – 600 000 USD	5% of the first 148 000 USD, 10% of the next 235 000 USD and 15% of the remainder
600 001 USD – 1 900 000 USD	5% of the first 148 000 USD, 10% of the next 235 000 USD, 15% of the next 217 000 USD and 20% of the remainder
1 900 001 USD – 10 700 000 USD	5% of the first 148 000 USD, 10% of the next 235 000 USD, 15% of the next 217 000 USD, 20% of the next 1 300 000 USD and 25% of the remainder
Over 10 700 000 USD	5% of the first 148 000 USD, 10% of the next 235 000 USD, 15% of the next 217 000 USD, 20% of the next 1 300 000 USD, 25% of the next 8 800 000 USD and 33.33% of the remainder

Change currency
(if your country uses a currency that is also used in other countries, please choose the country in which you live):

Note: This currency conversion takes into account not only exchange rates but also differences in purchasing power, as given by the International Monetary Fund with minor adjustments for some more recent changes in value. Please inform us of any errors.

If your currency is not listed, or if you prefer to make your own calculation, you can go to http://www.xe.com to convert your currency to US dollars. You can also take account of differences in purchasing power by using this map . You may, of course, use any other source you have available to convert the US dollar figures.

***

You ask

If possible could you please also include info on the multiplication
for different currency and std of living/purchasing power?

But that is on the websites listed, ie xe.com and the map. Since these change frequently, we can't list figures for all the different currencies.

best wishes,

Support Team,

Thanks very much, that is exactly what I needed.

I have been looking at the pledge calculation page, which does not
have the algorithm -http://www.thelifeyoucansave.com/pledge/
pledge_calc.php

I recommend that you put the standard or a link to it - at the bottom
the pledge calculation page as well. I spent some time looking for the
algorithm but did not think it would be on the pledge page. I thought
it would be under the 'how much should you give' link from the front
page.

Eg

... use any other source you have available to convert the US dollar
figures

How is this calculation made?

The standard

Income Bracket Donation

Less then 105 000 USD At least 1% of your income, getting
closer to 5% as your income approaches 105 000 USD

etc

Thanks again,

Lucian
