The £61bn contributed to the economy by over-65s "redefines what it is to be an 'older person'" according to Age UK.
Caroline Abrahams, charity director of Age UK said the usefulness of those over the age of retirement should not be overlooked, particularly as Britain had an ageing population:
These figures demonstrate the huge contribution that older people are making to our economy.
To put them in perspective, local authorities in England currently spend considerably less - just under £10 billion - on social care for older people.
Many will be surprised by just how much older people contribute but it's time we appreciated that they are playing a more and more important part in creating our prosperity.
Older people bring a great deal of knowledge, skill and energy, as volunteers and as paid employees, and in doing so they are redefining what it means to be 'an older person'.
Workers over the age of retirement helped to generate £61bn for the UK economy last year, according to new figures from charity Age UK.
Over 65s contributed via employment, informal caring and volunteering, Age UK said.
The Age UK Chief Economist's report found that £37 billion of the total amount came from employment and £11.4 billion from informal caring.
Childcare contributed £6.6 billion and nearly £6 billion came from volunteering.
A key credit rating agency has upgraded its opinion of the future prospects for the UK economy in light of its "robust and broadening" recovery.
Standard & Poor's (S&P) affirmed its top AAA rating on British sovereign debt and said it was switching its outlook from "negative" to "stable".
S&P has forecast growth of nearly 3% this year and 2.5% in 2015, saying it did not think fast-rising London house prices posed a risk to stability and that future rises would be "more contained".
But it warned that the rating would be at risk should Britain vote to leave the EU in the in/out referendum promised by David Cameron if the Conservative Party wins the next General Election.
The head of the International Monetary Fund has welcomed the UK's economic progress over the last year but warned of major risks that remain.
Delivering the IMF's annual report on the state of the British economy, Christine Lagarde said that "the news coming out of the UK has been pretty much all good".
She pointed to the UK's growth rate being the highest of the advanced economies, along with signs that the economy is "rebalancing" towards a more investment-driven economy.
However, she also identified two major risks to Britain's prosperity - weak productivity and the the rapid rise of house prices.
"There is no room for complacency as there are risks looming on the horizon," Ms Lagarde said.

A graduate who is not making a living wage told Daybreak how her "life is on hold" until she is able to get better paid work.
Penny Cook, 24, graduated with a first but has been unable to find full time work and earns £7 per hour in a retail job.
The three constituencies with the most workers earning less than the living wage are all in the south of England, according to figures from the TUC.
- Kingswood, near Bristol has 48% of constituents working for less than the living wage.
- London's Chingford and Woodford Green have 43.4% of constituents working for less than a liveable wage.
- Harrow West had 42.4%.
- However, other London constituencies had the lowest number of underpaid workers. In Poplar and Limehouse on 5.6% of the population earned less than £8.80 per hour.
- Runneymede and Weybridge had only 5.8%.
Almost 50% of the jobs on offer in some parts of the UK are paying less than the living wage, according to data from a leading trade union.
The TUC said a breakdown of official figures showed around 20% of workers were taking home less than the living wage for the area they lived in.
However, in some constituencies this rose to 50%.
The TUC said this amounted to five million people working for less than the living wage, with some of the worst offending areas in parts of outer London.
The living wage comes in at £8.80 per hour in London and £7.65 for the rest of the country.
Chancellor George Osborne has declared his commitment to fight for "full employment" in Britain.
Speaking to workers at Tilbury Port in Essex, he said his "ambition" was for Britain to achieve the highest employment rate of any of the developed nations of the G7.
Former Conservative chancellor Norman Lamont has told ITV News he is "not in any way uncomfortable" with George Osborne's comments that mass unemployment would never be a price worth paying.
Lord Lamont famously said in 1991, "Rising unemployment and the recession have been the price that we've had to pay in order to get inflation down, but that is a price worth paying".
