How much will I have if I pay £200 a month into a pension?

Started at 30, it could build a pot of about £114,095 by 67 in today's money. Taking 4% a year from that would give roughly £380 a month before tax, on top of the State Pension. Whether that's enough depends on the income you want in retirement.

It makes a big difference. If your employer added £150 a month, the same £200 from age 30 could grow to about £182,552 by 67.

In this example, £200 is what you pay, and basic-rate tax relief tops it up to £250 (relief at source). If your workplace scheme takes contributions before tax (net pay), turn tax relief off and enter the full amount. Without the top-up, £200 a month from 30 grows to about £91,276.

Contributions from now until 67, 5% investment growth a year, 0.5% annual fees and 2.5% inflation, with the result shown in today's money. Returns aren't guaranteed. Change any of them in the calculator.

Starting at 30 with basic-rate tax relief, £100 a month could grow to about £57,047 by 67 in today's money, and £500 a month to about £285,237.

A pension gets tax relief going in (so £200 becomes £250 for a basic-rate taxpayer) and often employer contributions, but you usually can't touch it until 55 (57 from April 2028), and most withdrawals are taxed. An ISA has no tax relief going in, but you can take the money out tax-free at any time. Many people use both.
