Database Design Table for forecasting
The "typical" method for accomplishing this type of design is something like this:



You could use pivot functionality to show the data in a table format, similar to your example.  In SQL Server this might look something like:

SELECT *
FROM (
    SELECT names.MilestoneName
        , FY = CONVERT(varchar(4), YEAR(dates.MilestoneStartDate)) 
                + '-' + CONVERT(varchar(4), YEAR(dates.MilestoneEndDate))
        , [Money Spent(Budgeted)] = CONVERT(varchar(20), details.MoneySpent) 
                + ' (' + CONVERT(varchar(20), details.MoneyBudgeted) + ')'
    FROM dbo.MilestoneDetails details
        INNER JOIN dbo.MilestoneDates dates 
            ON details.MilestoneDateID = dates.MilestoneDateID
        INNER JOIN dbo.MilestoneNames names 
            ON details.MilestoneID = names.MilestoneID
) src
PIVOT (
    MAX(src.[Money Spent(Budgeted)])
    FOR
        src.FY IN (
            [2015-2016]
            , [2016-2017]
            , [2017-2018]
        )
    ) pvt

This is the code to create the tables, etc, if anyone is interested:

IF OBJECT_ID(N'dbo.MilestoneDetails', N'U') IS NOT NULL
DROP TABLE dbo.MilestoneDetails;
IF OBJECT_ID(N'dbo.MilestoneDates', N'U') IS NOT NULL
DROP TABLE dbo.MilestoneDates;
IF OBJECT_ID(N'dbo.MilestoneNames', N'U') IS NOT NULL
DROP TABLE dbo.MilestoneNames;

CREATE TABLE dbo.MilestoneDates
(
    MilestoneDateID int NOT NULL IDENTITY(1,1) 
        CONSTRAINT PK_MilestoneDates
        PRIMARY KEY CLUSTERED
    , MilestoneStartDate datetime NOT NULL
    , MilestoneEndDate datetime NOT NULL
);

CREATE TABLE dbo.MilestoneNames
(
    MilestoneID int NOT NULL IDENTITY(1,1) 
        CONSTRAINT PK_MilestoneNames
        PRIMARY KEY CLUSTERED
    , MilestoneName varchar(48) NOT NULL
);

CREATE TABLE dbo.MilestoneDetails(
    MilestoneID int NOT NULL
    , MilestoneDateID int NOT NULL
    , MoneySpent decimal(18, 4) NOT NULL
    , MoneyBudgeted decimal(18, 4) NOT NULL
    , CONSTRAINT PK_MilestoneDetails 
        PRIMARY KEY CLUSTERED 
        (MilestoneID ASC, MilestoneDateID ASC)
);

ALTER TABLE dbo.MilestoneDetails  WITH CHECK 
ADD  CONSTRAINT FK_MilestoneDetails_MilestoneDates FOREIGN KEY(MilestoneDateID)

ALTER TABLE dbo.MilestoneDetails CHECK CONSTRAINT FK_MilestoneDetails_MilestoneDates

ALTER TABLE dbo.MilestoneDetails  WITH CHECK

    , (N'2016-01-01T00:00:00', N'2017-01-01T00:00:00')

INSERT INTO dbo.MilestoneDetails (MilestoneID, MilestoneDateID, MoneyBudgeted, MoneySpent)
