The figures show the United Kingdom finally recovering from the impact of the financial crisis, he said, declaring himself "Tigger-like" in a reference to the enthusiastic tiger in Winnie-the-Pooh.
Hammond said growth would stand at 1.3 percent in both 2019 and 2020, unchanged from previous forecasts.
But Hammond, delivering a half-yearly update on the government finances, said Britain's budget forecasters expected the economy to expand by 1.5 percent in 2018, up only a touch from a forecast of 1.4 percent in November even though the world economy is growing strongly.
The figures for 2018 represent an upgrading of the Office for Budget Responsibility's (OBR) forecast for growth, from 1.4% to 1.5%. The smaller than expected improvement means the Chancellor was not able to announce an important milestone in being on course to eliminate the current budget deficit this year (2017/18). "As a result, the government's headroom against its fiscal targets is virtually unchanged".
Borrowing for 2017-18 is expected to come in at £45.2bn, down from the £49.9bn forecast in November and by 2021-22 is expected to have more than halved to £21.4bn.
"Forecasts are there to be beaten", Hammond told MPs.
The economy was proving resilient "thanks in part to the willingness of consumers to maintain spending by reducing their saving", the OBR added.
Hammond stressed he had to keep on bringing down Britain's public debt levels but tried to focus on the positives, highlighting the OBR's prediction of a return to growth in spending power for households in early 2019.
"The fall in average hours over the second half of 2017 is the largest since mid-2011 and second largest since the financial crisis".
"So the Government's commitment to investing more in digital initiatives, such as 5G test beds, is welcome but yet more is needed if this region and the country's productivity growth is to be improved".
"A shorter valuation period undoubtedly has benefits in terms of the speed at which value changes are passed on to ratepayers and it should avoid the massive step change we saw in 2017", said Alex Probyn, president of United Kingdom business rates at real estate advisor Altus Group.
Summing up the OBR's report, Howard Archer, chief economic adviser to the EY Item Club, said: "There was continued caution in the deficit projections. the OBR's forecast implies that the strong gains in the fiscal position - seen so far this year - almost grind to a halt".
Debt was set to drop as a share of GDP from 2018/2019 and the OBR has revised down both debt and borrowing in every year. "The chancellor will no doubt be hoping that the economic and fiscal position looks sunnier as the year progresses, enabling him to dispense some giveaways in the Budget".
A "Tigger-like" Philip Hammond sounded an upbeat note as he claimed Britain was bouncing back and that improving public finances could open the door to public spending increases.
